What the F4 display means
The oven control has spotted something wrong. The cause listed for F4 is a possible fault in the oven cavity control, or the wiring that connects to it.
The reset routine
Turn the breaker off or pull the plug for one (1) minute.
Reconnect the power.
Remain by the oven for a minute to see if the same code appears.
Verify that the oven operates.
If F4 shows up again after a reset, arrange a service visit.
Our Whirlpool wall oven repair page covers San Francisco and the Bay Area, and the line is (415) 687-4102. It helps to know the oven model, that the code is F4, and which steps you have already done.
Model compatibility: Whirlpool reuses codes across series and model years, so F4 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
