F4E5 on KitchenAid ovens concerns the microwave weight sensor or wiring. Reset power; call if it comes back.
Model compatibility: KitchenAid reuses codes across series and model years, so F4E5 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
What this code means
Possible problem with the Microwave Weight Sensor or its wiring.
What does F4E5 point at? The microwave section’s weight sensor, or the wiring leading to it, according to KitchenAid. No other part appears in the entry.
At a glance
| Code | F4E5 |
|---|---|
| What it means | Possible problem with the Microwave Weight Sensor or its wiring. |
| What you can check | Switch the oven's breaker off, and after sixty seconds switch it on. Stay by the oven for a minute; if F4E5 does not show, do something simple in the oven to be sure it works. |
| When to call a technician | If F4E5 repeats, call rather than experiment. There is no way for an owner to test the weight sensor, and no statement that continued use is safe. |
Weight sensor basics
A weight sensor, generally speaking, measures the heaviness of a load. The KitchenAid page does not say how the oven applies the weight or where the sensor is installed.
The first test
Switch the oven’s breaker off. After sixty seconds switch it on. Stay by the oven for a minute; if F4E5 does not show, the first test is passed. Then do something simple in the oven to be sure it works.
Things KitchenAid leaves out
| Item | Status in the article |
|---|---|
| Emptying or moving things in the microwave | Not mentioned |
| Testing the sensor yourself | No method |
| Whether a returning code is harmless | Not said |
So if the code repeats, call rather than experiment.
Safe to use the microwave?
KitchenAid does not make a safety statement either way; it offers a reset and then service.
Do I need the model number?
Not according to the entry, but it saves time to have it when you phone.
