Jenn-Air Oven Error Code F1EA-2

F1EA-2 indicates that the main ACU (Appliance Control Unit) has detected an over-temperature condition due to a shorted ACU temperature sensor. The control board monitors its own operating temperature through a dedicated sensor, and when that sensor shorts, the board triggers this fault to protect itself. The oven will not function normally while this code is active. Diagnosing it requires checking wiring connections at the control board and testing the sensor circuit.

It is not recommended to continue using the oven while F1EA-2 is active. This code indicates a fault in the control board's own temperature monitoring circuit, and operating the oven with a compromised control system could lead to unpredictable behavior. Disconnect power to the range and have the fault diagnosed before resuming normal use.

Repair costs vary depending on the root cause. If the fix is simply reseating a loose connector, there may be no parts cost, though a service call fee typically applies if a technician is involved. Replacement of a wiring harness or temperature sensor generally falls in the range of $50 to $150 for parts. If the main ACU control board requires replacement, parts alone can range from $150 to $400 or more, with additional labor costs on top.

Some cases of F1EA-2 can be resolved by a confident DIYer by unplugging the oven, inspecting all connectors at the main control board, and reseating any that appear loose or unseated. However, if the fault persists after checking connections, further diagnosis requires testing sensor resistance and voltage, which involves working near the control board and wiring. If component replacement is needed, a qualified appliance repair technician is recommended to ensure correct part selection and safe installation.

Unplugging the oven or disconnecting power at the breaker may temporarily clear the code, but if the underlying fault with the sensor or wiring remains, F1EA-2 will return once power is restored and the control runs its diagnostics. A reset alone is not a repair. The root cause, whether a shorted sensor, damaged wiring, or a failed ACU board, must be identified and corrected to permanently resolve the fault.
