Whirlpool Wall Oven Code F4 E5: Checking the Weight Sensor Circuit

Medium · inspection needed

Code: F4 E5
Appliance: Wall Oven
Brand: Whirlpool
Warranty: 30-day workmanship

What F4 E5 means

F4 E5 on Whirlpool wall ovens with a microwave section, for instance the WOC54EC7HS, refers to the microwave weight sensor or the wiring joined to it. The oven uses that sensor to measure the load in the cavity. When the reading cannot be trusted, the display shows F4 E5 and weight-based cooking or the whole microwave may be unavailable. A sudden odd value from the sensor is what triggers the code.

Common causes of F4 E5

Microwave weight sensor
Wiring and connector at the sensor
Control receiving the weight signal

✓ One safe check you can try

1. Empty the microwave section completely. 2. Take the oven off its breaker for sixty seconds, then switch it back on. 3. Spend a minute near the display looking for F4 E5. 4. If the display is steady, test the microwave with a short run.

! Why to stop there

A reset gives no hint why the weight reading looked wrong.
We check the sensor and its wiring before the control.
Items left on the microwave floor or tray can affect how it reads, so we ask how it was being used.

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.

F4 E5F4 E5 questions

Does an item on the tray cause F4 E5?

The guidance do not list that as a cause. Still, take everything out of the cavity before you reset, so the oven starts from an empty reading.

Why would a weight sensor trigger a code?

If the control reads a signal outside what it expects, it flags the circuit instead of cooking blind. F4 E5 is that flag. Reseating anything behind the panel is not something owners should attempt.

Do I need a visit if F4 E5 clears?

If it clears and stays clear, you may carry on. If it comes back, the sensor circuit is the place to look, and we can do that with a written price first.
