What 1c31 means on a Maytag oven

Error code 1C31 indicates the control board has detected a problem with the cancel key circuit on the upper or single oven. Specifically, the board monitors the resistance of the cancel key and expects a reading between 1000 and 6600 ohms. When the measured resistance falls outside this range, the control disables the audible feedback for key presses and shuts down all outputs, meaning the oven will not heat and cannot be operated normally. The fault is isolated to the cancel key circuit, not the broader keypad assembly, though the two are physically connected through the membrane switch and wiring harness.

For homeowners, this means the oven's control board detected something wrong with the Cancel button. The button may be stuck, shorted internally, or the wiring connecting it to the control board may be damaged or corroded. Because the control shuts down all outputs when this code is active, the oven will not respond to commands and will not produce heat until the fault is resolved. This is a protective behavior, not a secondary failure. Checking the cancel key's resistance with a multimeter is the correct first diagnostic step before replacing any parts.

Common causes of 1c31

  1. 01

    Cancel key out of resistance range

    Part replacement

    The cancel key itself has failed internally, producing a resistance reading outside the 1000-6600 ohm window the control board expects. This can result from a worn or shorted membrane switch contact beneath the key.

  2. 02

    Damaged or corroded wiring harness to cancel key

    Part replacement

    The wiring harness connecting the cancel key circuit to the control board may have a broken wire, pinched insulation, or corroded connector pin, causing resistance to read incorrectly at the board.

  3. 03

    Cancel key stuck or mechanically bound

    Wiring / connection

    Physical debris, grease buildup, or a warped panel can hold the cancel key in a partially depressed state, creating a continuous or abnormal signal in the circuit that triggers the fault.

  4. 04

    Faulty control board

    Part replacement

    If the cancel key and wiring harness both test within the correct resistance range, the control board itself may be misreading the circuit due to a failed input component on the board.

Frequently asked questions about 1c31

What does error code 1C31 mean on a Maytag oven?
Error code 1C31 means the control board has detected a problem with the cancel key circuit on the upper or single oven. The board measures resistance at the cancel key and expects a value between 1000 and 6600 ohms. When the reading falls outside that range, the control disables all outputs and the audible key response, so the oven will not operate until the fault is cleared.
How do I fix error code 1C31 on a Maytag oven?
Start by unplugging the oven and using a multimeter to measure the resistance across the cancel key contacts. A reading between 1000 and 6600 ohms is normal. If the reading is outside this range, the membrane keypad or touchpad assembly will need to be replaced. If the key tests correctly, inspect the wiring harness connector between the keypad and the control board for corrosion, broken wires, or loose pins. If both test correctly, the control board may be at fault.
Can I still use my Maytag oven with error code 1C31 active?
No. When the 1C31 code is active, the control board disables all outputs, which means the oven will not heat regardless of what keys are pressed. The oven is not usable in this state and the fault must be resolved before normal operation can resume. The shutdown is a designed protective response, not a secondary malfunction.
How much does it cost to fix a 1C31 error on a Maytag oven?
If the cause is the membrane keypad or touchpad assembly, parts typically run between $50 and $150 depending on the model, and replacing the keypad is a DIY-accessible repair for someone comfortable disconnecting ribbon cables. If the control board is the cause, parts can range from $100 to $300, and the job is more involved. A professional diagnostic visit generally adds $75 to $150 in labor before any parts cost.
Will unplugging my Maytag oven reset the 1C31 error code?
A power reset may temporarily clear the code if the fault was caused by a transient electrical issue, but 1C31 will return as soon as the control board re-reads an out-of-range resistance at the cancel key circuit. If the underlying cause is a failed keypad or damaged wiring, the code will reappear and the oven will again disable all outputs. A reset is worth trying, but it does not substitute for testing the cancel key resistance.
