My Whirlpool microwave, model, WML55011HW07, is showing a F1E4 error code

Short summary:

  1. Identify the problem: If your microwave displays error 1E4, this indicates a stuck relay on the main display control board.
  2. Attempt a reset:Power down the microwave by turning off the circuit breaker for one minute.
    Power up the microwave by turning the circuit breaker back on.
    Monitor the microwave for one minute to check if the error code reappears.
  3. Address the underlying problem: If the error remains even after resetting the power, the entire display board may need replacement. This is a task best handled by a technician due to its complexity.
  4. Check the warranty: Visit the manufacturer's website and input the serial number of your microwave to check if your unit is still under warranty.

I understand

A fan is blowing hot air inside the unit.

You'd need to replace the entire display board to fix this issue if unplugging the microwave for 5 minutes doesn't reset the problem.

It's frustrating when appliances break. I had this model too and ran into the same error code, it turned out to be a costly repair.

My microwave displayed the same error. Power cycling did the trick for me!
