Jenn-Air Oven Error Code FC

FC on a Jenn-Air oven means the main control board and the power relay board (PRB) have lost communication with each other. The signal path between these two boards, carried through the J2 wiring harness, has been interrupted. The oven cannot operate safely without this communication link, so it shuts down and displays the code.

No. The FC code means the power relay board cannot receive commands from the main control board, which means the oven cannot control its heating elements reliably. Using the oven in this state risks uncontrolled heating behavior. Keep the oven off until the fault is diagnosed and repaired.

A reset, done by cutting power at the breaker or unplugging the oven for 60 seconds, will sometimes clear the FC code temporarily if the fault was caused by a one-time electrical glitch. However, if FC returns after the reset and a normal cook cycle, the underlying problem with the J2 harness or the power relay board is still present and needs physical inspection and repair.

Start by disconnecting power to the oven for at least 60 seconds and restoring it to see if the fault clears. If FC returns, you need to access the control area and inspect the J2 wiring harness, checking that all connectors are fully seated, free of corrosion, and that no wires are visibly damaged. If the harness checks out, the next step is replacing the power relay board (PRB). If replacing the PRB does not resolve it, the main control board may also need replacement.

If only the J2 harness connection is loose, the repair costs nothing beyond your time. A replacement J2 wiring harness, if the wiring is damaged, typically runs $20 to $60. A replacement power relay board (PRB) for Jenn-Air ovens generally costs $80 to $200 depending on the model. If a service technician is needed for diagnosis and installation, expect $100 to $200 in labor on top of parts. Homeowners comfortable with appliance disassembly can handle the harness inspection and PRB swap themselves.
