Samsung Oven door won't unlock/locks intermittently
When your Samsung oven door won't unlock or the oven door locks intermittently, the door lock motor and switch assembly is the most likely cause, especially after a self-cleaning cycle. This assembly activates the lock motor and confirms that the door is secured. Test the motor and switch assembly for electrical continuity with a multimeter and replace it if it fails. A defective door switch is the next likely problem. If you do not hear the door lock motor run when you press the self-clean button, test the door switch with its plunger pressed. A damaged door latch or failed latch microswitch can also leave the oven door locked. If the motor, switch, and latch test correctly, the Samsung oven touchpad, control panel, or user control and display board may not be sending voltage to the motor. Testing for voltage can help identify the faulty control. Always disconnect power before testing or replacing parts. Enter your Samsung range, stove, or oven model number to find the exact replacement door lock motor and switch assembly, door switch, door latch, touchpad, or control board for your appliance.
01 - Samsung 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 - Samsung 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 - Samsung 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 - Samsung 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 - Samsung 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 - Samsung 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.
