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

There may be a problem with the Smart Pop Control or the associated wiring.

F4E9 in plain terms

On over-the-range Whirlpool microwaves, F4E9 says the Smart Pop Control or the wiring connected to it may be faulty. The part itself is for a technician to inspect.

The reset below comes straight from the manual: breaker off for 1 minute, breaker on, one minute of watching, then a check that the microwave operates.

Compare with these

  • F4E1 concerns the Cavity Temperature Thermistor.
  • F6E0 points to the Appliance Control Board.
