F3E9 and the lower sensor
The entry for F3E9 lists the lower oven temperature sensor, the control and the wiring as possible trouble spots. It is written for wall ovens, and the first move is a simple power reset.
Reset the power
Switch the breaker off, or unplug the oven, for a minute.
Restore power.
See if F3E9 comes back, and verify operation afterward.
If the code returns, a technician is the next step.
A technician can take over where the reset stops. Use Whirlpool wall oven repair for San Francisco and Bay Area homes or call (415) 687-4102, quoting F3E9, the oven model number and what you have tried.
Model compatibility: Whirlpool reuses codes across series and model years, so F3E9 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
