Jenn-Air Range Error Code LOCK

A flashing LOCK message on a Jenn-Air range indicates an electronic control error that the appliance cannot resolve on its own. It is not the same as a normal door lock engagement during a self-clean cycle. The control board has detected a fault, which may involve the door lock assembly, its associated sensors, or the board itself. The issue requires diagnostic attention and may need a service technician if a reset does not clear it.

A reset will clear the LOCK error if the fault was caused by a transient issue such as a power surge or a temporary control board glitch. However, if the flashing returns immediately after power is restored, the reset has not resolved the underlying problem. In that case, a component such as the door lock actuator, a sensor, or the control board itself likely needs to be inspected and tested.

Repair costs depend on which component has failed. If the fix requires only a service call and a control board reset, costs will be limited to the technician's diagnostic fee, which typically ranges from $75 to $150. If a door lock actuator, sensor, or control board needs replacement, parts and labor combined can range from $150 to $450 or more depending on the specific part and your location.

You can attempt the recommended reset steps yourself without any special tools. First, press the CANCEL pad on the control panel. If the flashing continues, disconnect power to the range at the breaker or by unplugging it, wait a few minutes, and then restore power. If LOCK continues to flash after that, the fault is hardware-based and requires a qualified technician to diagnose and repair.

You should not continue using the range while the LOCK error is actively flashing. The indicator signals that the electronic control system has encountered a fault it cannot manage, and operating the appliance in this state is not advisable. Disconnect power and avoid using the range until the issue has been diagnosed and resolved.
