Quick answer

What F1E4 means on a Whirlpool over-the-range microwave and how to try a power reset.

What this code may mean.

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

The oven could not execute the function. There may be a problem with the Appliance Control Board, or the associated wiring.

When F1E4 appears on the display, the manual says there may be a problem with the Appliance Control Board or the associated wiring. The oven could not execute the function. The help article covers over-the-range microwaves.

What to do first

Step What to do
1 Cut power by turning off the breaker (or unplugging the microwave) for one (1) minute.
2 Bring power back with the breaker, or by plugging in again.
3 Use one (1) minute to monitor the microwave and check the display.
4 Run the microwave to verify its operation.

If the microwave still shows F1E4, ask a qualified technician for help.

Other codes to compare

  • F1E1 – another code about the relay control board.
  • F2 deals with the keypad; easy to mix up with this one.
  • F2E1 is worth comparing, since it concerns the user interface and keypad.
