Whirlpool Oven F9 — What It Means & How to Fix It
Also shown as F9 E0, F9E0 on some models.
F9 or F9 E0 most often means the wall oven is wired incorrectly at the home supply or hard-wire connection — have a qualified electrician verify it; after an outage, a power reset may clear it.
What this code means
Whirlpool says this code will most often indicate that the appliance is wired incorrectly at the home electrical supply or at the hard-wire connection, for example L2 and N swapped. It can also appear after a power outage if the control saw line "noise" as incorrect voltage, or if keys were pressed within the 10-second delay at power-up.
Whirlpool wall ovens, especially just after installation.
