Maytag Range Error Code FC

FC stands for a communication error between the main control board and the Power Relay Board (PRB). The PRB controls high-voltage switching for heating elements and other components, and when the signal between the two boards is lost, the range generates this code. The fault can originate from a wiring harness problem or a failure of the PRB itself.

It is not recommended to continue using the range while the FC code is active. The communication failure between the control board and the Power Relay Board means the control system cannot reliably manage the high-voltage switching circuits that operate the heating elements. Using the appliance in this condition could lead to unpredictable behavior or a safety hazard.

Repair costs depend on whether the fault is simply a wiring connection issue or requires a new Power Relay Board. A harness reseating or terminal repair by a technician will typically cost less, covering labor only. If the PRB needs replacement, total costs including parts and labor generally range from around $150 to $350 or more depending on the specific model and local labor rates.

A knowledgeable DIYer can start by unplugging the range and inspecting the J2 harness connector at both the main board and PRB for loose, burnt, or corroded terminals and reseating any connections. If the harness is intact and secure, resolving the fault will require replacing the Power Relay Board, which involves working inside a unit with high-voltage components and is best handled by a qualified technician.

Resetting the range by unplugging it for a few minutes may temporarily clear the FC code, but the error will return if the underlying cause is not corrected. If a harness connector was simply jarred loose, reseating it after a reset may resolve the issue permanently. If the PRB has failed, the code will reappear and a component replacement will be necessary.
