Oven control and door lock error codes mean the electronics, the keypad or the door latch reported a fault, often right after a self-clean cycle or a power surge.
GE uses F1 for a control fault, F7 for a stuck or shorted keypad button and F9 for a door lock problem. Whirlpool and Maytag use F1 for the control and F2 for the keypad. Samsung shows C-d0 or C-d1 when the door lock does not respond.
Self-clean puts the latch and electronics through high heat, and a power surge from a storm can upset the control. A keypad cleaned with a wet cloth can also report a stuck button.
When the oven powers on but the code points to the temperature probe, oven temperature probe codes explain the fix. Board, keypad and latch replacement are handled through range control and door latch repair.
GE F1, F7 and F9 and Samsung C-d0 are the control and lock codes searched most; keypad and lock codes can clear after a reset, while F1 board faults are marked stop.

Codes are listed for identification. Meanings vary by model, so confirm the code in your owner’s manual.
Control and lock codes are the oven codes most often caused by self-clean and power surges. Some clear permanently after a reset; others mean a part has failed.
GE F1 is a control board fault. F7 means a keypad button is stuck or shorted, often after liquid reached the panel. F9 points to the door lock motor or switch.
GE F9 often appears during or after self-clean, when the latch is under heat.
Whirlpool-built ranges show F1 or F1 E0 for the control and F2 or F2 E0 for the keypad. A keypad ribbon cable that has come loose can cause F2.
Samsung C-d0 and C-d1 mean the door lock did not respond as expected. Turning off power for a few minutes often clears a one-time fault.
A five-minute breaker reset after the oven has cooled clears many of these codes for good.
A control or lock code needs a technician when it returns after a cooled-down breaker reset. Call for service when:
Error Code FAQs
Control and lock code questions usually follow a self-clean cycle or a power surge.
F9 is a door lock error. Let the oven cool, reset the breaker and try again. If the door stays locked, the latch or its motor may need service.
F7 means a keypad button is stuck or shorted. Dry the panel and reset the breaker. If it returns, the keypad may need replacing.
C-d0 means the door lock is not responding. Turn off power for a few minutes, then restart, and call if it does not clear.
F1 is a control board fault. Reset the breaker for five minutes; if F1 returns or the oven heats on its own, call for service.
The door stays locked until the oven cools below a safe temperature. If it stays locked once cool, the lock motor or switch may have failed.
Tell the company whether the code came after self-clean or a storm.
