Whirlpool Oven door won't unlock/locks intermittently
If your Whirlpool oven door won't unlock after a self-cleaning cycle or locks intermittently, the door lock motor and switch assembly is the most likely cause. This oven door lock mechanism activates during self-cleaning, and a failed motor or switch can leave the oven door locked. Test the assembly for electrical continuity with a multimeter and replace it if it fails. A defective door switch is another common cause, especially if you do not hear the lock motor run when you press the self-clean button. Next, inspect the door latch for damage and test its microswitch, if equipped. If the motor and switches test correctly, the touchpad may not be sending voltage to the motor. Less commonly, a faulty control panel or user control and display board can prevent the lock from operating. Always disconnect power before testing or replacing parts, and do not force an oven door locked after self-clean. Enter your model number to find the exact Whirlpool replacement part for your range, stove, or oven, including the correct door lock motor, door switch, latch, touchpad, or control board.
01 - Whirlpool Range/Stove/Oven Door Lock Motor and Switch Assembly
During the oven's self-cleaning cycle, the door lock switch activates the door lock motor to prevent the oven door from being opened. If the door lock motor and switch assembly is defective, the oven door will not unlock once the self-cleaning cycle is complete or may only lock intermittently. You can use a multimeter to test the motor and switch assembly for electrical continuity. If the door lock motor and switch assembly does not test positive for continuity, the assembly should be replaced.

Highly Likely
02 - Whirlpool Range/Stove/Oven Door Switch
A defective door switch may prevent the oven door from unlocking or only locking intermittently. If you can't hear the door lock motor running when the self-clean button is pressed, use a multimeter to test the door switch for electrical continuity. If the door switch does not test positive for continuity when the plunger is pressed, the component should be replaced.
Common
03 - Whirlpool Range/Stove/Oven Door Latch
If the door lock motor does not test positive for electrical continuity, it's possible the door latch is defective. Inspect the latch for damage. You can also use a multimeter to test the latch assembly's microswitch, if applicable, to determine if the switch has appropriate electrical continuity. If the latch is damaged or the microswitch tests negative for continuity, the door latch should be replaced.
Common
04 - Whirlpool Range/Stove/Oven Touchpad
If the door lock motor tests appropriately for electrical continuity, but the oven door still won't unlock or locks intermittently, it's possible that the touchpad is defective and unable to properly control the door lock motor. To help determine this, you can test for voltage reaching the door lock motor. If no voltage is reaching the motor, it's likely the touchpad requires replacement.
Less Common
05 - Whirlpool Range/Stove/Oven Control Panel
If the door lock motor tests appropriately for electrical continuity, but the oven door still won't unlock or locks intermittently, it's possible that a control panel component is defective and the panel is unable to properly control the door lock motor. To help determine this, you can test for voltage reaching the door lock motor. If no voltage is reaching the motor, it's likely the control panel requires replacement.
Less Common
06 - Whirlpool Range/Stove/Oven User Control and Display Board
If the door lock motor tests appropriately for electrical continuity, but the oven door still won't unlock or locks intermittently, it's possible that the user control and display board is defective and unable to properly control the door lock motor. To help determine this, you can test for voltage reaching the door lock motor. If no voltage is reaching the motor, it's likely the user control and display board requires replacement.
