F3 E2 on a Whirlpool Built-In Microwave: Which Oven Sensor to Test

Medium · inspection needed

Code: F3 E2
Appliance: Microwave
Brand: Whirlpool
Warranty: 30-day workmanship

What F3 E2 means

For F3 E2, the manufacturer names the oven temperature sensor, the control, or the wiring on Whirlpool built-in microwaves and microwave drawers such as WMC50522AS. Unlike F3 E0 and F3 E1, which name the upper and lower sensors, F3 E2 refers to the oven sensor without saying which position. The display shows the code and no further part is named, so we use it to decide which circuit to test.

Common causes of F3 E2

Oven temperature sensor
Wiring between the sensor and the control
Control board

✓ One safe check you can try

1. Power the oven down at its breaker. 2. Wait one minute. 3. Power it up. 4. Stand by for a minute and see whether F3 E2 shows up again. 5. When the display stays clear, try a quick cycle to be sure the oven performs. 6. When it does not, have us look at the sensor circuit.

! Why to stop there

A reset only restarts the control and cannot tell us which of the three areas is responsible.
We read the sensor circuit directly and compare it with what the control expects.
If a repair would not make sense on an older oven, we say so before you spend anything.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F3 E2F3 E2 questions

Why does F3 E2 not say upper or lower?

The guidance for this code names the oven temperature sensor in general. We identify the exact sensor on the oven during the visit. Which sensor it is gets settled during the visit.

Is F3 E2 a safety warning?

The brand does not describe it as one. It is a sensor circuit code, but an oven that cannot read its own temperature should not be relied on until it is checked.

What if the reset works only for a day or two?

That pattern suggests a connection or sensor that comes and goes. It is worth a proper test, and we explain what we find in plain language.
