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.

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).
Common Problems This Part Fixes
Dryer suddenly stopped heating with no warning — thermal cutoff has blown after an overheat event
Dryer runs and tumbles normally but produces no heat
No-heat fault following a partially blocked exhaust vent or restricted airflow event
Multimeter continuity test shows the cutoff has an open circuit (no continuity)
Visible damage or discoloration around the thermal cutoff housing from a prior overheat event
Repeated no-heat problems where the thermal cutoff has tripped more than once
Replaces Part Numbers
This thermal cutoff fuse directly replaces the following OEM and cross-reference part numbers:
8318314
If your part number is not listed above, contact our support team before ordering and we will verify compatibility.
Compatibility
This 352°F thermal cutoff fuse is compatible with select dryers from the following brands:
Whirlpool dryers (Elite, Cabrio, Duet, and WED series — select models including WED9200, WED7300, WED7400, WED7600 and related)
Maytag dryers (Maxima and MED series — select models including MED3500, MED6000XW, MEDE900VW and related)
KitchenAid dryers (select models)

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.

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.

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 4449751 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 an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Whirlpool OEM part, but is manufactured to match the trip temperature (335°F / 170°C), auto-reset function, terminal configuration, and fit of the original WP4449751 high limit thermostat used in compatible Whirlpool, KitchenAid, Maytag, Jenn-Air, Amana, and Kenmore ovens.
