KitchenAid Wall Oven F4E6 Code: Wave Guide Temperature Sensor
F4E6 is about the microwave wave guide temperature sensor or its wiring. A breaker reset is the only owner step listed.
Model compatibility: KitchenAid reuses codes across series and model years, so F4E6 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 Wave Guide Temperature Sensor or its wiring.
F4E6 sits on the microwave side of a KitchenAid wall oven. KitchenAid points to two things: the microwave wave guide temperature sensor, and the wiring that connects to it.
At a glance
| Code | F4E6 |
|---|---|
| What it means | Possible problem with the Microwave Wave Guide Temperature Sensor or its wiring. |
| What you can check | Remove power from the oven at the breaker and wait a minute. Switch it back on, watch the display for one minute for F4E6, then confirm the oven is running. |
| When to call a technician | If F4E6 is back after the reset, arrange service. No instructions exist for opening the microwave section or reaching the sensor, so that work belongs to a technician. |
Quick note on wave guides
Generally a wave guide is a metal passage that carries microwave energy from its source to the cooking compartment. With a temperature sensor on it, the control can check how warm the passage has become. The KitchenAid text gives no acceptable temperature.
Power reset, paraphrased
Remove power from the oven at the breaker and wait a minute. Switch it back on, then watch the display for one minute to find out if F4E6 shows itself again. Finally, confirm the oven is running.
