Jenn-Air Oven Error Code F1EA-1

F1EA-1 indicates that the main ACU (Appliance Control Unit) has detected an over-temperature fault due to an open circuit in its internal temperature sensor. The control board monitors its own temperature to protect the electronics, and an open sensor means it is not receiving a valid signal. The oven shuts down as a precaution until the problem is corrected.

No, you should not use the oven while this code is active. The ACU temperature sensor is a protective component, and operating without a functioning sensor means the control board has no way to detect if it is overheating. Continued use risks further damage to the electronics and should be avoided until the fault is resolved.

If the fix is simply reseating a connector, there may be no parts cost at all, only your time or a service call fee. If the main ACU control board needs replacement, parts and labor costs typically range from $200 to $500 or more depending on your model and local labor rates. Getting a diagnostic estimate from a technician before committing to the repair is advisable.

You can start with the basic diagnostic step yourself: unplug the oven and inspect all connectors at the main control board for loose or unplugged connections. If reseating the connectors does not clear the fault, testing the sensor circuit with a multimeter and replacing the control board typically requires comfort with appliance electronics. A qualified technician is recommended if you are not experienced with board-level diagnostics.

Disconnecting power for several minutes may temporarily clear the code, but if the underlying cause, such as an open sensor or loose connector, has not been addressed, the error will return. A power reset is useful as part of the diagnostic process but is not a fix on its own.
