Quick answer

Meaning of F4E9 on a Whirlpool wall oven and the power reset Whirlpool lists.

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 microwave inverter, or the associated wiring.

Finding F4E9 on the control panel of a Whirlpool wall oven means the oven has logged a problem. What it points to: the microwave inverter together with its wiring. Whirlpool words it as a possible problem, not a confirmed one.

It is listed for wall ovens in the product help.

What to try first

  1. Switch off the circuit breaker, or unplug, and count one (1) minute.
  2. Turn the power on.
  3. Monitor the oven for one (1) minute.
  4. Verify that everything runs normally.

If the code returns after the reset, the next step is service.
