KitchenAid Range Error Code LOCKED

LOCKED is a safety status message indicating the oven door is engaged by the automatic latch mechanism because the oven temperature is still too high following a self-clean cycle. The control board monitors the oven temperature sensor and keeps the door latch motor engaged until the cavity cools below a safe release threshold. This is normal behavior designed to prevent burns or damage from opening a very hot oven. No error or fault has occurred if the oven recently completed or cancelled a self-clean cycle.

The LOCKED display after self-cleaning indicates the oven is extremely hot and still cooling, so normal cooking should not be attempted until the door unlocks and the oven returns to room temperature. Do not try to force the door open, as this can damage the latch assembly, door handle, or door gasket. Once the door releases and the oven has cooled, normal operation can resume. If the oven displays LOCKED without a recent self-clean cycle, discontinue use and inspect the door latch and sensor circuit before operating the appliance.

If the oven simply needs time to cool, there is no repair cost. Replacement of a failed oven temperature sensor typically costs between $20 and $80 for the part, with labor adding $75 to $150 if a technician is called. A door latch assembly replacement generally runs $30 to $100 for parts plus similar labor costs. A control board replacement is the most expensive scenario, with parts ranging from $150 to $400 or more depending on the model, plus labor.

Start by waiting one to two hours for the oven to cool completely to room temperature after a self-clean cycle. If the door remains locked after full cooling, try turning off the range at the circuit breaker for one to two minutes, then restoring power to reset the control board. If the door is still locked after a reset and the oven is confirmed cool, the temperature sensor, door latch motor, or control board likely needs to be diagnosed and replaced.

A control board reset by cycling power at the circuit breaker can sometimes clear a LOCKED condition that persists after the oven has fully cooled, particularly if a power interruption occurred during the self-clean cycle. However, if the oven is still hot, a reset will not override the safety interlock and the door will remain locked until the temperature drops to the release threshold. If a reset does not resolve the issue on a fully cooled oven, component-level diagnosis is needed.
