Monogram Range F8 Error: Door lock mechanism failure
The F8 error code on a GE Monogram range indicates that the door lock mechanism has failed or is not operating within expected parameters. The control board cannot confirm that the oven door is properly locked or unlocked, and halts operation to prevent the self-clean cycle from running with an unsecured door.

Answer to continue safely
Is it safe to keep using?
Maybe. Normal baking and broiling functions may still work if the door seals properly. Do not attempt to run the self-clean cycle until the door lock mechanism is repaired, as temperatures during self-clean exceed 800 degrees Fahrenheit and an unsecured door is dangerous.
Can I reset the code?
No. A power-cycle may clear the F8 code if the fault was a one-time sensor glitch. If the mechanical lock assembly is worn or broken, the code returns every time a self-clean is initiated.
When to stop immediately?
Stop if you notice: Stop attempting self-clean cycles until the door lock mechanism is confirmed working., Stop use entirely if the oven door cannot be held firmly closed during baking due to a failed latch..
Symptoms You May Notice
Oven door will not lock at the start of or during the self-clean cycle.
F8 fault code is displayed on the control panel, stopping the self-clean or bake cycle.
Door lock motor can be heard running continuously or cycling on and off without fully engaging.
Self-clean cycle aborts within the first few minutes before the oven reaches cleaning temperature.
Possible Causes
Worn or broken door lock motor assembly — the actuator that physically throws the latch bolt has failed mechanically.
Requires ProfessionalFaulty door lock switch or position sensor that fails to report the locked or unlocked state to the control board.
Requires ProfessionalFood debris or grease buildup around the door latch strike, physically preventing the lock bolt from fully engaging.
DIY PossibleSafe Checks You Can Do
-
1
Clean the door latch area
With the oven cool and unplugged, inspect the door latch and strike plate area around the top of the oven door frame. Remove any baked-on grease or food debris using a non-abrasive cleaner and a soft cloth.
Never use metal tools to scrape the latch area — you can deform the strike plate and worsen the alignment.

2
Power-cycle the range
After cleaning, restore power and allow the range to complete its startup sequence before attempting the self-clean cycle again. A fresh power cycle resets the door lock motor controller.
If the lock motor runs but does not complete its travel, the motor assembly itself has likely failed and requires replacement.
When to Call a Professional
Contact a qualified technician if:
- The door lock motor runs but the bolt does not fully engage, indicating a mechanical failure inside the lock assembly.
- F8 returns on every self-clean attempt after cleaning the latch area and resetting the range.
