Maytag Range Error Code 1c31

Code 1c31 means the control board detected an improper voltage or resistance value coming from the cancel key circuit on the upper or single oven cavity. The board expects a specific signal range from that key, and something in the cancel key, its wiring, or the keypad membrane is returning a value outside that range. Start by inspecting the cancel key for physical damage and checking the wiring harness connection at both the keypad and the control board.

A 1c31 code typically indicates the control board cannot confirm proper cancel key function, which means the oven may not respond to control inputs reliably or may refuse to operate at all. Using the range in this condition is not recommended because the control system may not respond correctly to commands, including shutdown commands. Resolve the fault before resuming normal use.

Unplugging the range for five minutes will clear the code temporarily, and if the fault was caused by a transient electrical glitch the code may not return. However, if there is a physical problem with the cancel key membrane, wiring harness, or control board, the code will reappear after the reset. A reset is a useful first step but not a repair on its own.

Begin by unplugging the range for five minutes to reset the control board. If the code returns, check the wiring harness connector between the membrane keypad and the control board for loose or corroded pins. Test continuity through the cancel key circuit. If the cancel key membrane is torn, shorted, or stuck, replace the keypad assembly. If the keypad tests good and wiring is intact, the control board likely needs replacement.

If the fix is a membrane keypad replacement, parts typically run between $50 and $150 depending on the model, and the repair is manageable for a confident DIYer since it usually involves removing the control panel and unplugging a ribbon cable. If the control board needs replacement, parts can range from $100 to $300 or more. Labor from a technician adds $100 to $200 on top of parts. Diagnosing the cancel key and wiring yourself first can avoid paying for an unnecessary board replacement.
