KitchenAid Wall Oven F4E5 Error Code

An unusual sensor

Weight sensors are rare in ovens, yet F4E5 names one in the microwave section. KitchenAid says the microwave weight sensor or its wiring may be at fault, and lists nothing else.

Background in plain words

Generally, a weight sensor tells how heavy a load is. KitchenAid does not explain how the oven uses that information or where the sensor sits. Beyond the part’s name, nothing further is stated.

Reset steps

1. At the breaker panel, flip the oven’s breaker off.
2. Count to sixty, then flip it on.
3. Remain near the oven for about a minute. If F4E5 does not show, the first test has passed.
4. Run a simple task on the oven to confirm it works.

Not covered by KitchenAid

• Emptying or repositioning anything inside the microwave.
• Any owner test for the sensor.
• A statement that the code is harmless if it returns.

With that in mind, a code that keeps coming back calls for a phone call rather than experiments.

Questions

Is the microwave unsafe to use with this code?
KitchenAid says nothing on safety. It gives a reset and, if the code stays, service.

Is the model number required?
The entry does not ask for it, though having it close helps when you speak with a technician.
