Whirlpool ranges — and the Maytag and KitchenAid ovens built on the same platform — report faults with F-codes. As with the brand’s washers and dryers, each code names a subsystem. Here is how we read the common ones on Denver Metro service calls.
F1 — control board fault
The electronic range control reported an internal error. A power cycle sometimes clears a one-off glitch after a surge; an F1 that returns points at the board — the most expensive guess on the machine, and exactly why it should be confirmed, not assumed. Heat-stressed boards above a poorly vented oven cavity are a pattern we know well.
F2 — over-temperature
The cavity reported hotter than commanded: a stuck heat relay, or far more often a drifting temperature sensor telling the control a story. Repeated F2 during self-clean is the classic aging-sensor signature. Real overheating is a safety issue — treat F2 with respect.
F3 / F4 — temperature sensor circuit
The oven sensor reads open (F3) or shorted (F4): the probe, its connector, or the harness. The most common and most affordable F-code family — and worth fixing early, because a drifting sensor ruins baking at “350” long before it hard-fails. The no-code version of this story lives in oven not heating.
F5 — door switch / lock circuit
The control and the door disagree: lock motor, switches or wiring, usually surfacing around self-clean. If the door locks and refuses to release, do not force it — the lock assembly is a routine part; bent linkages are not.
Why we don’t recommend guessing parts
F1 can be a surge glitch or a board; F2 a $40 sensor or a relay. Sensor resistance and relay behavior are measurable in minutes, and measuring first is what separates a $150 repair from a $400 parts gamble. Our diagnostic fee is credited toward the repair.

FAQ
Whirlpool, Maytag, KitchenAid ovens – same F-codes?
Broadly yes – same corporate platform, same control language. Exact definitions vary by model, which is why we confirm against the model number before ordering anything.
Does F1 always mean a new control board?
No – that is the expensive assumption. Surges cause one-off F1s, and harness or relay issues can mimic a bad board. Confirm first; boards are the most-misdiagnosed oven part.
Why does F2 show up mostly during self-clean?
Self-clean pushes the cavity to its hottest, where an aging sensor drifts most. It is the early-warning version of the fault – usually a sensor, occasionally a relay.
