Jenn-Air Oven Error Code F1E5-1

F1E5-1 indicates a secondary ACU fault caused by incorrect hardware feedback from the DLB (Double Line Break) relay. The control board monitors this relay, which manages 240-volt power delivery to the heating elements, and has detected a mismatch between the expected and actual relay status. The oven will typically interrupt normal operation until the fault is resolved.

Unplugging the oven or tripping the breaker for several minutes may temporarily clear the code, but it will return if the underlying cause is not corrected. A reset is useful as a first step to confirm whether the fault is intermittent or persistent, but it does not repair a failed relay or a faulty control board.

If the fix is simply reseating a loose connector, there may be little to no parts cost beyond a service call fee, which typically ranges from $75 to $150 depending on your area. If the main control board needs replacement, parts and labor combined generally range from $300 to $600 or more depending on the specific model and local labor rates.

The first step any technician would take is to disconnect power and inspect all wiring connectors at the main control board for loose or corroded connections, which is a task many capable DIYers can perform safely. If reconnecting all connectors does not clear the fault after restoring power, resolving the issue typically requires replacing the main control board, which involves working near line-voltage components and is best handled by a qualified technician.

The DLB relay is a safety-critical component that controls both legs of high-voltage power to the heating elements, and a confirmed fault in this circuit should be taken seriously. It is not recommended to continue using the oven for cooking until the fault has been diagnosed and repaired. Operating with a compromised relay feedback circuit could lead to element control issues or create an unsafe condition.
