Quick answer

The E03 display on over-the-range microwaves points to the keypad (user interface) or its wiring.

Model note: Whirlpool reuses codes across series and model years, so E03 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Whirlpool

What this code may mean.

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

Keypad (user interface) problem reported to the control board.

E03: the keypad is reporting trouble

The control board has been told by the keypad (user interface) that something is wrong, so the keypad or the wiring connected to it could be the issue. This applies to over-the-range microwaves.

Reset sequence

  • Power down at the breaker(s), wait 1 minute.
  • Power back up.
  • Monitor for 1 minute that the code stays off the display.
  • Verify normal microwave operation.
