Error codeF4E5
ApplianceWall Oven
Quick read: F4E5 on a Whirlpool wall oven concerns the microwave weight sensor. Whirlpool says there may be a problem with that sensor, or with the associated wiring, and lists the code for wall ovens.
Try this first
Cut power to the oven at the breaker, or unplug it, and keep it off for one (1) minute. Switch the power on again and monitor the oven for one (1) minute. Then verify that it operates. Whirlpool treats this as the first and only owner action.
If F4E5 comes back
An error that survives the reset needs a technician visit, so book one and keep the oven out of use until then.
Codes to compare
F4E4, the humidity sensor entry on the microwave side
F4E6, which names the wave guide temperature sensor
F4E3, which refers to the exhaust air temperature sensor
Wall oven repair in the Bay Area

Model compatibility: Whirlpool reuses codes across series and model years, so F4E5 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
