Kenmore Range Error Code F93

F93 on a Kenmore range indicates a door motor mechanism failure within the F90 to F94 fault code group. It means the control board has detected a problem in the automatic door locking system, which includes the lock motor, lock switch, and door switch circuits. This system is primarily used to secure the oven door during self-clean cycles. The fault appears when the locking or unlocking sequence does not complete as expected.

Normal baking and cooking functions may still be available depending on how the control board responds to the fault, but you should not attempt to run a self-clean cycle while this code is active. The door locking system is a safety feature designed to keep the oven door sealed during the high temperatures of a self-clean cycle. Operating the self-clean function with a faulty door lock mechanism could present a safety risk.

After attempting a power reset, the first physical inspection should focus on the wiring harness connected to the lock motor, lock switch, and door switch. Check for loose connectors, corroded terminals, or damaged wire insulation. If the wiring appears intact, each switch should be tested for proper continuity, and the lock motor should be checked to confirm it operates correctly when power is applied.

A power reset can sometimes clear the F93 code if it was triggered by a temporary glitch. Start by pressing the CLEAR key, and if the code persists, turn off power to the range for 30 seconds before restoring it. If the error returns after the reset, there is likely a physical problem with the lock motor, a switch, or the wiring that will need to be inspected and repaired.

Repair costs vary depending on which component has failed. A replacement lock motor or switch part typically ranges from $20 to $80 in parts alone. If a technician is needed for diagnosis and installation, total repair costs including labor can range from $100 to $300 or more. If the control board is the root cause, parts and labor costs can be higher.
