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.

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.

XPARTCO 3949247 Washer Lid Switch Replaces 3949247V
The XPARTCO 3949247 is an aftermarket replacement lid switch assembly for Whirlpool top-load washers, and also fits select Roper, Estate, Kenmore, Inglis, Crosley, Amana, and KitchenAid models, including stacked washer/dryer laundry center units. This switch mounts to the underside of the cabinet top panel and tells the washing machine the lid is closed, allowing the wash cycle to begin.
Black plastic with wire leads, sold individually. Over time, the plastic on the switch's actuator can become brittle with age and break when the lid is closed roughly, or from the movement of an unbalanced load causing parts of the washer to strike it. Symptoms of a failing lid switch include the wash cycle not starting even when the lid is closed, error codes related to the lid being open, inability to advance through cycle selections, or the washer not spinning while still agitating normally. It directly replaces 3949247V, 3949247, 3949237, 3949239, 3949240, 3949247VP, 4248251, TJ90ES247, AP3100003, ES247, AP5983746, AWP227261, EAP350434, OEM17951247, PD00024284, PS11722098.

Installation Notes
⚠️ Unplug Washer And Shut Off Water Supply Before Starting Unplug your washer from the wall outlet and turn off the water supply before beginning. Wear work gloves. Remove the screws holding the access panel in place at the back of the machine, then carefully remove the panel and set it aside. Locate the lid switch assembly near the top, center of the washer's interior. Use a Phillips and flathead screwdriver to unscrew the three screws that hold the lid switch assembly in place. Disconnect the wire harness from the old lid switch and carefully remove it from the machine. Install the new 3949247 into the machine in the exact same manner the old switch was removed. Connect the wire harness to the new switch. Reattach the three screws to secure the switch in place. Replace the access panel and reattach its screws. Turn on the water supply and plug in the washer. Run a test cycle with the lid closed to confirm the washer starts and spins normally. Tools needed: Phillips head screwdriver, flat head screwdriver.
Frequently Asked Questions
My washer agitates but won't spin. Is this the part I need?
Yes, this is a well-documented symptom of a failed lid switch. This switch tells the washer's control system that the lid is closed before allowing certain functions, and spin specifically often requires this signal — a failed switch commonly leaves agitation working while blocking spin.
Why does this switch fail over time?
The plastic on the switch's actuator can become brittle with age and break when the lid is closed roughly. It can also break from the movement of an unbalanced load causing parts of the washer to strike it during a cycle.
Is this the same as the 3949238 switch?
No, these are separate lid switch part numbers, despite the similar numbering. Our 3949238 listing is used on different models. Always confirm your exact part number from your washer's parts diagram or the sticker on your old switch before ordering.
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 to match the material, wiring, and switching function of the original 3949247V lid switch assembly used in compatible Whirlpool, Roper, Estate, Kenmore, Inglis, Crosley, Amana, and KitchenAid washers.
