Jenn-Air Range Error Code F9-3

F9-3 means the oven's control board is detecting conflicting signals from the motorized door lock assembly, indicating the door is both locked and unlocked at the same time. This is a logical fault that points to a problem with the door lock mechanism, its internal position switches, or the wiring connecting it to the control board. The oven cannot safely determine the actual state of the door lock, so it displays this code to alert you to the issue.

Resetting the range by cutting power at the breaker for a few minutes may temporarily clear the F9-3 code, but it will return if the underlying fault in the door lock or wiring is not repaired. A reset is useful for confirming whether the fault is intermittent, but it is not a fix. The door lock assembly and its wiring connections need to be physically inspected and addressed.

If the repair only requires reseating a loose wiring connection, there is no parts cost. Replacing the motorized door lock assembly typically costs between $50 and $150 for the part, depending on the model, plus labor if you hire a technician. A professional service call with parts and labor combined generally runs in the range of $150 to $350, though costs vary by region and service provider.

Checking and reseating the wiring harness at the door lock assembly is a straightforward task that many DIYers can handle with basic tools. If the wiring is secure and undamaged, replacing the motorized door lock assembly is the next step and is also a manageable repair for someone comfortable working with appliances. Always disconnect power to the range before inspecting or replacing any components.

Because the control board cannot confirm whether the door is properly locked or unlocked, the oven may disable the self-clean function and could restrict other operations as a safety precaution. Using the range for standard baking or broiling may still be possible, but you should avoid running the self-clean cycle until the door lock fault is resolved. Have the lock assembly inspected promptly to restore full safe operation.
