Whirlpool Microwave Error Code F7 — Stuck Function Key
What this means
The F7 error code on Whirlpool microwaves indicates a function key is stuck on the control panel. The control board is receiving a continuous signal from one of the touchpad buttons. This can be caused by a worn membrane switch, a stuck physical button, moisture behind the control panel, or a control board input failure.
Step-by-step fix
3 stepsPress each button to check for stuck keys
Press and release every button on the control panel. Feel for any button that doesn't spring back or feels mushy.
Cooking grease and moisture can make touchpad buttons stick over time.
Power cycle the microwave
Unplug for 5 minutes. If a temporary moisture or static issue caused the phantom button press, the reset will clear it.
Wipe the control panel clean with a dry cloth after resetting.
Replace the control panel
If the error persists, the membrane switch panel needs replacement. This is typically the outer door panel assembly, which can be replaced without accessing internal high-voltage components.
The door panel assembly includes the touchpad and sometimes the display — verify your model's part.
When to call a professional
If replacing the control panel doesn't resolve the issue, the control board inside the cabinet has a faulty input, requiring professional service.
