Code overview at a glance.

The facts for this Whirlpool error, a plain-language snapshot, and what to confirm against your model number.

Error code F9
Appliance Wall Oven
Quick answer

F9 on Whirlpool wall ovens: The oven is most often wired incorrectly at the home electrical supply or the hard-wire connection.

Model note: Whirlpool reuses codes across series and model years, so F9 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code may mean.

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

The oven is most often wired incorrectly at the home electrical supply or the hard-wire connection.

F9 (also shown as F9 E0) most often means the oven is wired incorrectly at the home electrical supply or at the hard-wire connection. It is listed for Whirlpool wall ovens.

Reset steps from the manual

  1. Think about the installation. Make sure every terminal is wired correctly and that L2 and N are not swapped, and have a qualified electrician verify that the electrical supply was installed correctly.
  2. Reset power: turn the circuit breaker off for one minute, turn it on again, and watch the oven for one minute to confirm the code does not display again.
  3. Verify oven operation.

A power outage can cause it too. If the control detects an unexpected amount of line noise as an incorrect voltage, it may display F9, F9 E0 or PF. Pressing keys before the 10-second delay on power-up can do the same.
