Error codeF4 E5
ApplianceWall Oven
What a F4 E5 reading tells you
When F4 E5 appears, the oven is hinting at trouble with the Microwave Weight Sensor or with wiring tied to that sensor. The message is specific to wall ovens, so it belongs to the microwave side of a combination unit.
Cycle the breaker before anything else
Find the breaker (or breakers) serving the oven and switch it to off. Wait a whole minute.
Flip it back on so the oven powers up again.
Stay near the display for a minute and see if F4 E5 comes back.
Finally, run the oven briefly to make sure it operates.
If the message keeps returning, the sensible next move is a technician visit rather than more resets.
Neighbouring F4 messages
F4 E4 concerns the microwave humidity sensor and the appliance manager.
F4 E6 concerns the microwave wave guide temperature sensor.
