Quick answer

F4E4 points to a possible Humidity Thermistor or wiring problem. Reset power at the breaker for one minute and watch for the code.

Model note: Whirlpool reuses codes across series and model years, so F4E4 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code may mean.

A plain-language reading of the code — always confirm against your model’s documentation.

There may be a problem with the Humidity Thermistor or the associated wiring.

F4E4 is the Humidity Thermistor message on over-the-range Whirlpool microwaves. According to the manual, the thermistor or the wiring connected to it may be at fault.

What to do first

Cut power at the breaker for a full minute, then restore it and let the display run for one more minute to see whether F4E4 reappears. Run the microwave afterwards to confirm it operates. If you would rather not use the breaker, unplug the microwave for the same length of time.

If another code shows

Thermistor codes sit close together. F4E1 is tied to the Cavity Temperature Thermistor, while F3T1 refers to the User Interface Thermistor.
