XPARTCO 8318314 Dryer Thermal Cutoff Fuse (352°F)
The XPARTCO 8318314 is an aftermarket replacement 352°F thermal cutoff fuse compatible with a wide range of Whirlpool, Maytag, KitchenAid, Kenmore, Amana, Crosley, Roper, Inglis, and Estate dryers. The thermal cutoff fuse is a critical safety device mounted near the heating element housing — it acts as a backup safety in case the high-limit thermostat fails to open. When the air temperature inside the heating element area reaches 352°F, the fuse permanently opens and cuts power to the heater circuit, preventing the dryer from continuing to overheat and creating a fire risk.
This is a one-time fuse — once it has tripped, it cannot be reset and must be replaced. White and gray metal/ceramic construction. Dimensions: 1-1/4"L x 1-1/4"W x 2-3/16"H, with approximately 1-5/8" between mounting holes (center to center). It directly replaces 8318314. Important: when the thermal cutoff blows, the high-limit thermostat (8557403 — sold separately) is often also stressed and should be tested or replaced at the same time. Installs in 15–20 minutes with basic hand tools.
Quick Answer
The XPARTCO 8318314 Dryer Thermal Cutoff Fuse (352°F) fixes Whirlpool, Maytag, KitchenAid, Kenmore, Amana, Crosley, Roper, Inglis, and Estate dryers that suddenly stopped heating after an overheat event. One-time fuse — 352°F open, must be replaced once blown. 1-1/4"L x 1-1/4"W x 2-3/16"H, ~1-5/8" between mounting holes. Metal/ceramic. Often replaced alongside the high-limit thermostat (8557403, sold separately).

Installation Notes
⚠️ Unplug Dryer Before Starting — Clean Vent System First Disconnect power before beginning. Wear work gloves to protect your hands. Before installing the new thermal cutoff, thoroughly clean the dryer's vent line — from the lint screen through the duct to the exterior wall outlet, plus any internal lint buildup around the heater housing. A blown thermal cutoff is virtually always caused by restricted airflow; if you don't fix the underlying cause, the new fuse will trip again soon. Access the thermal cutoff by removing the rear (or front, depending on model) access panel of the dryer to expose the heating element housing. The 8318314 thermal cutoff is mounted on or near the heater housing. Photograph the wire connections before disconnecting. Disconnect the wires from the old cutoff and remove the mounting screw(s). Install the new 8318314 cutoff in the same position and reconnect the wires. While the panel is open, this is also the ideal time to test or replace the high-limit thermostat (8557403) — overheat events that blow this fuse often damage that component too. Reassemble the panel, restore power, and run a test heat cycle to confirm normal heat operation. Tools needed: Phillips screwdriver, 1/4" nut driver, multimeter, work gloves.
Frequently Asked Questions
What's the difference between a thermal cutoff, a thermal fuse, and a high-limit thermostat?
All three are safety components in a dryer's heating circuit but they serve different roles. The high-limit thermostat (such as 8557403 or 3391914) is a resettable safety switch — it opens when the air gets too hot, then closes again automatically once it cools. The thermal cutoff (8318314, 352°F) is a one-time fuse on the heating element circuit — it blows permanently if the temperature exceeds 352°F, meaning the high-limit thermostat failed to do its job. The thermal fuse (often 3392519) is a separate one-time fuse mounted on the exhaust duct — it blows if exhaust airflow temperature exceeds its rating. Each protects against a different failure mode and is replaced individually when it blows.
Why did my thermal cutoff blow in the first place?
A blown thermal cutoff is almost always the result of restricted airflow through the dryer. The most common causes are: a clogged or kinked exhaust vent line, a clogged lint screen, lint buildup inside the dryer cabinet near the heater housing, or a failed blower wheel/motor that's not moving enough air. Less commonly, a failed high-limit thermostat (stuck closed) can let the dryer overheat until the thermal cutoff blows as a last-resort safety. Before replacing this part, identify and fix the underlying airflow issue — otherwise the new fuse will blow within a short time.
Should I replace the high-limit thermostat at the same time?
Yes, it's highly recommended. The thermal cutoff is the second line of defense against overheating — for it to trip, the high-limit thermostat ahead of it likely failed to open at its normal cycling temperature, was stressed by the overheat event, or was already weakened. Replacing the high-limit thermostat (8557403 on many compatible Whirlpool-platform dryers) at the same time is standard practice and ensures both safety components work correctly together. The 279973 kit even bundles a thermal cutoff with a high-limit thermostat for this reason.
Can the thermal cutoff be reset like a circuit breaker?
No — the 8318314 is a one-time thermal fuse. Once it opens at 352°F, it permanently breaks the electrical circuit and cannot be reset. Some appliance components (like a high-limit thermostat) can reset automatically as they cool, but a thermal cutoff fuse is a single-use safety device by design. If your dryer suddenly stopped heating and a continuity test on this fuse shows an open circuit, it must be replaced.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Whirlpool OEM part, but is manufactured from metal and ceramic with the same 352°F trip temperature, dimensions (1-1/4"L x 1-1/4"W x 2-3/16"H), and mounting hole spacing (1-5/8" center to center) as the original 8318314 thermal cutoff fuse.

AGM30045804 Genuine OEM LG Dryer Thermistor and Thermostat Kit
The AGM30045804 is a genuine LG OEM high-limit thermostat and thermistor kit for LG dryers. These two components work together in the same temperature-regulation circuit: the thermistor is a temperature sensor, mounted in the blower housing with its wire harness included, that continuously reports drum temperature to the control board so it can fine-tune heat output throughout the cycle. The high-limit thermostat is a safety switch that automatically shuts off the heating element if temperatures climb past a safe threshold, then resets itself once the dryer cools, without needing to be replaced the way a thermal fuse does.
Because these two parts share the same circuit and tend to wear or fail around a similar timeline, LG sells and services them together as one kit rather than as separate individual parts. Symptoms of failure in this circuit include the dryer overheating (which can scorch clothing or, left unaddressed, pose a fire risk), the dryer running with little or no heat, drying times that have become inconsistent, an error code related to temperature control on the display, or clothes coming out damp after a full cycle. It directly replaces 6931EL3003C, 6323EL2001B, 6931EL3003F, 6931EL3004B, AP7206815, EAP16732335, and PS16732335.
Quick Answer
The AGM30045804 Genuine OEM LG Dryer Thermistor and Thermostat Kit fixes LG (and select Kenmore, GE-branded LG-built) dryers with overheating, little or no heat, inconsistent drying times, a temperature-related error code, or clothes coming out damp after a full cycle. High-limit thermostat + thermistor with wire harness. Replaces 6931EL3003C, 6323EL2001B, 6931EL3003F, 6931EL3004B, AP7206815, EAP16732335, PS16732335. If you've already replaced the high-limit thermostat alone and the problem returns, this combined kit — which also addresses the thermistor — is the next step.

Installation Notes
⚠️ Unplug Dryer Before Starting — Let It Cool Fully First Disconnect power at the outlet or shut off the circuit breaker before beginning, and allow the dryer to cool completely if it was recently run. Wear work gloves. Access on many LG models follows this general sequence: remove the lint screen, then remove the two front panel screws underneath it, the two screws on the face of the panel, and the two screws holding the blower cover in place. Disconnect the door switch connector and remove the front panel. With the front open, release the drive belt from the tensioner and remove the drum to access the blower housing where the thermistor is located. Photograph the wiring connections before disconnecting anything, since the thermistor and high-limit thermostat can be easy to confuse with other similar-looking components nearby. Disconnect and remove the old thermistor and high-limit thermostat, noting their exact mounting positions. Install the new components from this kit in the same positions, reconnecting wiring exactly as photographed. Reinstall the drum, re-tension the belt over the tensioner, and reassemble the front panel, blower cover, and lint screen area in reverse order. Restore power and run a full test cycle to confirm normal, consistent heating with no premature shutoffs. Tools needed: Phillips screwdriver, nut driver, work gloves.
Frequently Asked Questions
I already replaced the high-limit thermostat, but it keeps tripping. Why would I need this kit instead?
This is a well-documented pattern. If the thermistor — the sensor that reports temperature to the control board — is misreading heat, the control can keep driving the heating element past the point where the high-limit thermostat has to trip repeatedly to protect the dryer, even with a brand-new thermostat installed. Replacing the thermistor alongside the thermostat addresses the root cause rather than just the symptom, which is exactly why LG packages them together as one kit.
What's the difference between the thermistor and the high-limit thermostat?
The thermistor is a sensor, not a switch — it's a variable resistor whose resistance changes with temperature, and the control board reads that value continuously to regulate heat output throughout the cycle. The high-limit thermostat is a safety switch that does one job: it shuts off the heating element automatically if temperature exceeds a safe limit, then resets itself once things cool down. A failing thermistor causes inconsistent or inaccurate heat regulation; a failing high-limit thermostat causes the dryer to shut off unexpectedly or fail to protect against overheating.
My parts diagram shows more thermostat-like parts than what's in this kit. Did I order the wrong thing?
Not necessarily — some LG dryer models have additional related components, such as a separate blower thermostat, that are not part of this specific kit. This kit covers the high-limit thermostat and thermistor. If your repair calls for additional related parts, or if you're not sure exactly which components your model needs, contact our support team with your model number and we'll help you confirm the complete parts list before you order.
Is this an OEM or aftermarket part?
This is a genuine OEM part, manufactured by LG to factory specifications — guaranteed fit, materials, and performance. It includes the same resistance values, switch threshold, and wire harness configuration as the high-limit thermostat and thermistor originally installed in your dryer.

279769 Genuine OEM Whirlpool Dryer Thermostat Kit
The 279769 is a genuine Whirlpool OEM thermal cut-off and high-limit thermostat kit for Whirlpool, Kenmore, Roper, KitchenAid, Maytag, Amana, Estate, Crosley, and Admiral electric dryers. This kit bundles two components that guard against overheating at different thresholds: the 3390291 high-limit thermostat (rated L250-80F) monitors internal temperature and interrupts power at approximately 250°F to prevent overheating, then resets itself automatically once the dryer cools — no replacement needed after each trip. The 3977394 thermal cut-off fuse is the backup: rated at 352°F, it's a one-time safety device that permanently opens the circuit if temperatures climb high enough that the thermostat alone didn't prevent an overheat.
These two parts are sold together and should be replaced together as a set, since they protect the same circuit and tend to be stressed by the same underlying problem. Whirlpool's own guidance is direct: when the thermal cut-off fails, it usually indicates a venting problem, and failing to correct that airflow issue will cause repetitive failures even with new parts installed. Symptoms include the dryer not heating, clothes coming out extremely hot, or the dryer not running at all. This kit is commonly used alongside heating element 4391960. It directly replaces 279548, 2796769, 279769VP, 2821, 2004, 3387812, 3389946, 3398671, 3977394, 695563, 80001, SET184, SET198, TJSET198, ET184, AP3094224, AH334278, EA334278, EAP334278, PD00002485, PS334278, WP3390291, AP6008306, 3390291, 696397, and PS11741441.
Quick Answer
The 279769 Genuine OEM Whirlpool Dryer Thermostat Kit fixes Whirlpool, Kenmore, Roper, KitchenAid, Maytag, Amana, Estate, Crosley, and Admiral electric dryers with no heat, no power at all, or clothes coming out dangerously hot. Includes the 3390291 high-limit thermostat (250°F, auto-resetting) and the 3977394 thermal cut-off fuse (352°F, one-time). Replaces 279548, 2796769, 279769VP, 3387812, 3389946, 3398671, 3977394, 695563, 80001, AP3094224, PS334278, WP3390291, AP6008306, 3390291, 696397, PS11741441. Always inspect and clean the exhaust venting when replacing this kit — a blown thermal fuse is a symptom of restricted airflow, and skipping the vent check leads to repeat failures.

Installation Notes
⚠️ Unplug Dryer Before Starting — Inspect And Clean The Venting Before Reassembling Disconnect power at the outlet or shut off the circuit breaker before beginning. Wear work gloves. Access is typically through the rear panel, near the heating element and blower housing where both components are mounted. Photograph the wiring connections before disconnecting anything, since the thermostat and fuse can be easy to swap positions by mistake. Remove each old component from its mounting position, noting orientation, and disconnect its wiring. Before reassembling, fully inspect and clean the dryer's exhaust vent, from the lint trap housing all the way to the exterior vent hood, checking for lint buildup, crushed sections, or excessive length. When the thermal cut-off fails, it usually indicates a venting problem, and failing to correct that airflow issue will cause repetitive failures even with these new parts installed. Install the new 3390291 thermostat and 3977394 thermal fuse from this kit in the same positions as the parts they replace, reconnecting wiring exactly as photographed. Reassemble the panel, restore power, and run a full test cycle to confirm normal, consistent heating with no premature shutoffs. Tools needed: Phillips or nut driver (model-dependent), work gloves.
Frequently Asked Questions
My clothes are coming out extremely hot, hot enough to burn my hands. Is this the right kit?
Yes, this is a documented symptom this kit addresses. If the high-limit thermostat fails to regulate temperature correctly, the dryer can run far hotter than it should, producing dangerously hot clothing at the end of a cycle. Whirlpool's own parts support has specifically pointed customers with this exact complaint toward this kit. Stop using the dryer if you notice this symptom and replace both components promptly.
Why do I need to replace both the thermostat and the fuse together?
These two parts protect the same circuit at different thresholds and tend to fail from the same underlying cause. If the high-limit thermostat isn't regulating temperature correctly, the thermal fuse often ends up blowing as the backup safety measure. Replacing only one risks the other failing again shortly after, so they're sold and serviced together as a set.
I replaced this kit and the dryer failed again. What should I check?
This is a strong sign the underlying cause — almost always restricted airflow — was never addressed. Thoroughly inspect and clean the entire exhaust path from the lint trap housing to the outside vent hood, checking for lint buildup, crushed or kinked ductwork, or a vent run that's too long. Failing to correct a venting issue will cause repetitive failures of this kit even when it's brand new.
Should I replace the heating element at the same time?
It's worth considering if your dryer's heating element (commonly 4391960 on compatible models) is original and has been running alongside a failing thermostat, since sustained overheating can stress the element as well. It's not required, but since you'll already have the panel open for this repair, it's a reasonable time to inspect the element for visible damage.
Is this an OEM or aftermarket part?
This is a genuine OEM part, manufactured by Whirlpool to factory specifications — guaranteed fit, materials, and performance. It includes the same temperature thresholds and mounting configuration as the high-limit thermostat and thermal cut-off fuse originally installed in your dryer.

Installation Notes
⚠️ Turn Off Power at Breaker Before Starting — This Is a 240V Oven Circuit — Wear Work Gloves Disconnect power at the household breaker before beginning — this is a 240V circuit and there is a serious risk of electrical shock if power is not fully disconnected. Verify power is off with a voltage tester before touching any wiring. Wear work gloves and safety glasses. Allow the oven to cool completely before beginning (several hours after any recent cooking). The high limit thermostat is typically mounted on the rear or side of the oven cavity, accessed by removing the back panel of the appliance (for freestanding ranges) or the front trim/service panel (for wall ovens). The exact location varies by model — consult your appliance's service diagram before starting. Photograph all wire connections and mounting details before disconnecting anything. Disconnect the wire terminals from the old thermostat (typically two spade-terminal wires). Remove the mounting screws or clips holding the thermostat to the oven cavity, and lift it out. Install the new WP4449751 in the exact same position and orientation — the thermostat must be in good thermal contact with the oven cavity to function correctly. Secure the mounting hardware and reconnect the wires to their correct terminals. Reinstall the access panels. Restore power at the breaker and test the oven — start with a low-temperature bake cycle to confirm normal heating operation before running a high-temperature or self-clean cycle. Tools needed: Phillips screwdriver, 1/4" nut driver, voltage tester (essential), work gloves, safety glasses.
Frequently Asked Questions
Why did my high limit thermostat trip in the first place?
A high limit thermostat trips because the oven exceeded its safe operating temperature — meaning something upstream in the temperature control chain failed to shut off the heating element when it should have. Common causes are: a failed oven control board (relay stuck closed), a failed cooling fan (allowing the oven cavity or electronics to overheat), blocked or restricted ventilation, poor door sealing (letting the cavity overheat), disrupted air circulation, or an abnormal self-cleaning cycle. Before installing the new thermostat, investigate and address the underlying cause — otherwise the new thermostat will trip again in short order. Also inspect the ventilation, oven door gasket, and cooling fan while you have the appliance open.
What's the difference between a high limit thermostat and the operating thermostat?
These are two different components serving two different roles. The operating thermostat (or the oven control board with its temperature sensor) is the primary component that maintains the oven at your set temperature by cycling the heating element on and off during normal operation — it opens and closes at your selected temperature (e.g., 350°F). The high limit thermostat (WP4449751) is a backup safety device that only trips when the oven temperature far exceeds normal operation (335°F over the cavity's safe threshold), typically because the operating thermostat or control has failed. If the high limit thermostat trips, both need to be checked — the operating thermostat may also need replacement.
Does the high limit thermostat reset itself, or does it need to be replaced after tripping?
The WP4449751 is an auto-reset thermostat — it closes automatically once the oven cools back to a safe temperature, allowing normal operation to resume. If your oven is heating normally again after cooling, the thermostat is likely still functional (the underlying overheating cause needs investigation). However, if the thermostat has failed permanently open — often the result of repeated overheat events or age — it will need replacement. Test with a multimeter set to continuity: a working thermostat shows continuity at room temperature. If it reads open (infinite resistance) when cold, it has failed and needs replacement.
Why does my self-cleaning cycle leave the oven door locked and the oven won't heat?
This is a classic symptom of a high limit thermostat that tripped during the self-clean cycle. Self-cleaning cycles run at extreme temperatures (800–1000°F) and stress every component in the oven — if the ventilation, door gasket, or cooling fan can't keep up, the high limit thermostat will trip open. Once tripped, the oven can't heat OR unlock the self-clean door lock mechanism, leaving the door stuck closed. Once the thermostat cools and closes (or is replaced), the door lock releases and normal operation resumes. If self-clean cycles routinely trip the thermostat, investigate whether the ventilation, cooling fan, or door gasket are causing the problem.
Can I do this repair myself, or should I hire a technician?
Replacing an oven high limit thermostat is a manageable DIY repair for someone comfortable with mechanical work and electrical connections, but this is a 240V circuit and the thermostat is a safety component — any error can create a serious safety risk. If you have experience with appliance repair, follow the safety precautions carefully (breaker off, voltage tester, correct thermostat orientation), and can confirm the wiring connections are secure, this is a feasible DIY. If you've never worked with 240V appliance circuits before, hiring a qualified appliance technician is the safer option. Also identify and address whatever caused the original overheat event — otherwise the new thermostat will trip again.
Is this a Genuine OEM or aftermarket part?
This is a Genuine OEM part manufactured by Whirlpool to factory specifications. It is the exact same high limit thermostat installed in compatible Whirlpool, KitchenAid, Maytag, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore ovens from the factory — guaranteed fit, materials, and performance. Backed by Whirlpool's one-year warranty on Genuine OEM parts.

XPARTCO XP6974 Dryer Thermostat Kit Replaces WP3387134, WP3392519, W10900067, 279816
The XPARTCO XP6974 is an aftermarket dryer thermostat kit containing four thermal components for Whirlpool-family electric and gas dryers including Whirlpool, Kenmore, Maytag, Amana, KitchenAid, Roper, Admiral, Estate, Crosley, Inglis, and Magic Chef. The kit includes the cycling thermostat (WP3387134), thermal fuse (WP3392519), high-limit thermostat and thermal cut-off kit (279816 / W10900067) — the complete set of heat-sensing and safety components that regulate dryer temperature and prevent dangerous overheating.
These four components work together to control and protect the dryer's heating system. When any one of them fails, the dryer may produce no heat, overheat, run too long, or stop mid-cycle. Because a failed thermal fuse is almost always caused by an underlying overheating condition that also stresses the other components, replacing all four together in a single repair is the recommended approach. Includes all wiring hardware needed for installation. Installs in 20–30 minutes with basic hand tools.
Quick Answer
The XPARTCO XP6974 Dryer Thermostat Kit fixes Whirlpool-family dryers that produce no heat, overheat, take too long to dry, or stop mid-cycle. Includes all four thermal components: cycling thermostat (L155-25), thermal fuse (196°F), high-limit thermostat (L250-80), and thermal cut-off (309°F). Compatible with Whirlpool, Kenmore, Maytag, Amana, KitchenAid, Roper, Admiral, Estate, Crosley, Inglis, and Magic Chef electric and gas dryers.
Common Problems This Kit Fixes

Installation Notes
⚠️ Unplug Dryer and Shut Off Gas Before Starting Disconnect power (and shut off gas for gas dryers) before beginning. Remove the back panel of the dryer to access the heating element housing and exhaust duct. The thermal fuse (WP3392519) and cycling thermostat (WP3387134) are located on the exhaust duct or blower housing — disconnect the wires, unscrew the mounting screws, and install the new parts in the same positions. The high-limit thermostat and thermal cut-off (279816 kit) are located on the heating element housing — disconnect the wires and unscrew the mounting screws to remove the old parts and install the new ones. Reconnect all wires to the correct terminals — take a photo before disconnecting to reference during reinstallation. Reassemble the back panel, restore power, and run a test cycle to verify heat. Tip: Before running the dryer, also clean the full length of the exhaust duct — a clogged vent is the most common root cause of dryer overheating and repeated thermal fuse failures. Tools needed: Phillips screwdriver, 1/4" nut driver, needle-nose pliers.
Frequently Asked Questions
What does each part in this kit do?
The cycling thermostat (WP3387134) monitors the air temperature in the exhaust duct and cycles the heating element on and off to maintain the correct drying temperature — it is the part that controls how hot the dryer gets during normal operation. The thermal fuse (WP3392519) is a one-time safety device that permanently cuts power to the heating element if the dryer overheats above 196°F — it is the most common cause of no-heat in Whirlpool-family dryers. The high-limit thermostat opens at approximately 250°F to cut heating element power if temperature gets too high, and resets automatically when it cools. The thermal cut-off is a backup one-time fuse on the heating element that opens at 309°F if the high-limit thermostat fails to protect the heater.
Why should I replace all four parts instead of just the one that failed?
When a thermal fuse blows, it almost always blew because the dryer overheated — and that overheating event put significant stress on all the other thermal components as well. A failing cycling thermostat is the most common cause of repeated thermal fuse failures: if the cycling thermostat stops regulating temperature correctly, the dryer runs too hot, the high-limit thermostat is repeatedly stressed, and the thermal fuse eventually blows. Replacing just the fuse without replacing the cycling thermostat means the same overheating will blow the new fuse. Replacing all four parts at once eliminates that risk in a single repair.
How do I test these parts with a multimeter?
Set the multimeter to continuity or resistance mode. The thermal fuse (WP3392519), cycling thermostat (WP3387134), and high-limit thermostat should all show closed continuity (near-zero resistance) at room temperature. The thermal cut-off should also show closed continuity at room temperature. Any part that reads open (no continuity / infinite resistance) at room temperature has failed and needs to be replaced. A blown thermal fuse or cut-off will always read open — they are one-time devices and cannot reset.
What causes the thermal fuse to blow repeatedly?
The most common cause by far is a clogged exhaust vent — lint accumulation inside the dryer duct restricts airflow, causing heat to build up inside the dryer cabinet until the thermal fuse trips. Always clean the full length of the exhaust duct before and after replacing these parts. Other causes include a failing cycling thermostat that is not regulating temperature correctly, a stuck heating element relay, or a dryer placed in an enclosed space without adequate ventilation.
Is this kit compatible with both electric and gas dryers?
Yes — the XP6974 kit is compatible with both electric and gas Whirlpool-family dryers. Both types use the same cycling thermostat (WP3387134) and thermal fuse (WP3392519). The high-limit thermostat and thermal cut-off (279816 kit) are located on the heating element in electric models and on the burner assembly area in gas models. Always verify your specific model number before ordering to confirm all four parts apply to your dryer.

XPMTC-180 Microwave Thermal Cut-Off Fuse 180℃ (356°F) – Normally Closed – Universal Microwave Safety Cutoff
Product Description
Protect your microwave from extreme overheating with the XPMTC-180 Microwave Thermal Cut-Off Fuse 180℃ (356°F), Normally Closed. This high-temperature safety device is designed to remain closed (conductive) during normal operation and open permanently when internal temperatures exceed 180℃, immediately cutting power to prevent serious damage or fire risk. A tripped thermal cut-off can cause the microwave to lose power or stop heating. Replacing it with the correctly rated NC fuse restores safe and reliable operation.

🔍 What’s the Difference Between NC and NO Thermal Cut-Offs?
Normally Closed (NC): Circuit is closed during normal operation and opens permanently when the rated temperature is reached.👉 Most microwave thermal cut-offs are NC.
Normally Open (NO): Circuit is open during normal operation and closes only when overheated (used in limited designs).
⚠️ Installing the wrong type (NC vs NO) may cause the microwave not to run or fail to protect against overheating.
