Jenn-Air Oven Error Code F1E5-E

F1E5-E is a secondary ACU fault indicating that the Convect 2 element relay or triac on the main control board has been detected as open. This means the switching component responsible for sending power to the second convection heating element is not completing the circuit. The oven may not function properly in convection modes until the underlying cause is resolved.

Using the oven in standard bake mode may be possible depending on which elements are affected, but convection cooking functionality will likely be unreliable or completely unavailable. It is not recommended to continue using the oven normally until the fault has been diagnosed, as an open relay or triac could indicate a broader control board issue. Always disconnect power before inspecting any components.

If the fix is as simple as reseating a loose connector, there may be little to no parts cost, though a service call from a technician typically runs between $75 and $150 just for the visit. If the ACU needs to be replaced, total repair costs including parts and labor generally range from $300 to $600 or more depending on the specific model and local labor rates. Replacing only the convection element, if that turns out to be the fault, is usually a less expensive repair in the $100 to $300 range.

A knowledgeable DIYer can start by unplugging the oven and inspecting all wiring connectors at the main control board for loose or unplugged connections, which is the recommended first diagnostic step. If connectors are secure, the repair typically involves testing the wiring harness and convection element for continuity, and potentially replacing the ACU. Replacing a control board requires comfort working with appliance wiring and electronics, so a professional technician is advisable if you are unsure.

Disconnecting power for several minutes may temporarily clear the fault display, but if the underlying cause such as a failed relay, damaged wiring, or faulty ACU is still present, the code will return when the oven is used again. A reset should be used as a diagnostic step to see if the fault is intermittent, not as a permanent solution. The root cause must be identified and repaired to fully resolve the error.
