Jenn-Air Oven Error Code 1c31

Error code 1c31 on a Jenn-Air oven means the control board has detected a failure in the cancel key circuit. Specifically, the analog-to-digital input reading from the cancel key is outside the acceptable range. As a result, the control board disables all oven outputs, and the oven will not operate until the fault is corrected.

When 1c31 is active, the control board disables all outputs, so the oven will not heat and cannot be used. This is a built-in safety response to the fault. Do not attempt to bypass the lockout; the oven should be repaired before returning it to service.

Repair costs depend on which component has failed. A replacement keypad assembly typically costs between $50 and $150 for the part, while a new control board can range from $150 to $400 or more depending on the model. Adding professional labor, total repair costs generally fall between $150 and $600. Getting a diagnostic service call from a technician can help pinpoint the failed component before committing to parts.

Some causes of 1c31 are DIY-accessible, such as reseating a loose ribbon cable connector between the keypad and the control board. However, if the keypad membrane or control board has failed, those components will need to be replaced. Working on the control panel requires disconnecting power to the oven first, and comfort with basic appliance disassembly is necessary.

A power reset, by turning off the circuit breaker for one to two minutes and restoring power, may temporarily clear the code if it was triggered by a transient electrical event. However, if the cancel key circuit or keypad hardware is physically damaged or faulty, the code will return. A reset alone is not a repair for a genuine component failure.
