Jenn-Air Oven Error Code F1E5-5

F1E5-5 is a secondary ACU fault code indicating the broil relay on the main control board is reading as open. The ACU is the central electronic control board, and its broil relay is the internal switch that sends power to the broil element. The control detected that this relay is not functioning correctly and shut down the broil circuit. This fault originates inside the control board itself rather than from an external sensor.

The broil function will not operate correctly with this fault active, so you should avoid using the broiler until the issue is resolved. Bake functions may still work depending on whether the fault has caused the control to lock out all oven operations. It is best to have the control board inspected before continued use to ensure no wiring damage is present.

If the repair only requires reseating a loose wiring connector, the cost is minimal beyond your time. If the ACU needs to be replaced, parts alone typically range from roughly $150 to $400 or more depending on the specific model, with professional labor adding additional cost. Getting a diagnosis from a certified technician before ordering parts is advisable to confirm the ACU is the failed component.

A knowledgeable DIYer can start by unplugging the range and inspecting all wiring harness connectors at the main control board for loose or disconnected terminals, which is a no-cost first step. If connections are secure and the fault persists after restoring power, the ACU most likely needs to be replaced, which involves disconnecting the wiring harness and swapping in a new board. Working on control boards does require comfort with appliance disassembly and electrical safety precautions.

Disconnecting power to the oven for several minutes may temporarily clear the code, but if the broil relay on the ACU has failed internally, the fault will return when the oven is powered back on or the broil function is activated. A reset is a useful first step to confirm whether the fault is persistent, but it does not repair the underlying hardware problem.
