Maytag Range Error Code F1:3

The F1:3 error code on a Maytag range indicates a shorted key condition within the membrane switch, which is the touch pad panel used to input cooking functions, temperatures, and timer settings. The membrane switch is a layered assembly of flexible circuits and conductive contacts. When a key is shorted, it means two conductive layers are making unintended contact, causing the control board to register a continuously pressed button even when no input is being made. This false signal disrupts normal operation and triggers the fault code.

The most common triggers for a shorted membrane switch include physical damage to the keypad surface, liquid infiltration beneath the membrane layers, or debris lodged between the flexible circuit layers. Spills are particularly damaging because residue left behind can bridge contacts permanently. Over time, normal wear can also cause the internal layers to degrade or stick together, creating a persistent short.

Diagnosis begins with a visual inspection of the membrane switch surface for cracks, bubbling, or visible contamination. If the keypad appears intact and clean, the fault likely lies in the internal circuit layers, which are not serviceable individually. In that case, the membrane switch assembly itself requires replacement. If replacing the membrane switch does not resolve the error, the electronic control board may also be at fault and would need to be replaced, as the control interprets and processes all signals from the membrane switch.
