Oven Fan Not Working? Gas Oven TroubleshootingDuring 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.
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.
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.
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.
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.
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.
The control board is responsible to for sending voltage to all of the oven's electrical components. If the door lock motor tests appropriately for electrical continuity, but the oven door still won't unlock or locks intermittently, it's possible the control board is defective. 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 board is faulty and requires replacement.
The main control board is responsible to for sending voltage to all of the oven's electrical components. If the door lock motor tests appropriately for electrical continuity, but the oven door still won't unlock or locks intermittently, it's possible the main control board is defective. 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 board is faulty and requires replacement.
