Jenn-Air Range Error Code FAULT DETECTED

FAULT DETECTED means the oven's control system has identified an abnormal condition either during programming or while the oven is running. It is a general fault signal rather than a code pointing to one specific component. The display will prompt you to press Power to clear the fault or press Enter to try the operation again. If the fault does not clear or returns repeatedly, a service technician should inspect the unit.

If the fault clears after pressing Power and the oven operates normally afterward, it is generally safe to continue using it while monitoring for recurrence. However, if the fault appears repeatedly during operation or the oven is not heating correctly, you should stop using it and contact an authorized servicer. Continuing to operate an appliance with a persistent control fault can pose safety risks.

The initial step of pressing Power to clear or pressing Enter to retry is something any user can do without tools or technical knowledge. If those steps resolve the issue, no further action is needed. However, if the fault persists, diagnosing the root cause requires testing components like the temperature sensor and control board, which involves working near line voltage and is best handled by a qualified technician.

Pressing Power as directed on the display will often clear the fault if it was caused by a transient glitch or an interrupted programming sequence. If the fault reappears after clearing, the underlying cause has not been resolved and resetting alone will not fix it. In that case, professional diagnosis is recommended.

Repair costs depend entirely on the root cause identified during diagnosis. If the fault is traced to a failed temperature sensor, parts and labor typically range from around 100 to 250 dollars. A control board replacement can run from 200 to 450 dollars or more depending on the specific model. A service call for diagnosis alone usually costs between 75 and 150 dollars before any parts.
