F8E5: a function was not executed, with the exhaust air temperature sensor named.
Model compatibility: KitchenAid reuses codes across series and model years, so F8E5 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
The oven could not execute the function; possible exhaust air temperature sensor or wiring problem.
Two statements accompany F8E5 on KitchenAid’s over-the-range microwave page. First, the oven was unable to execute that function. Second, a fault may lie in the exhaust air temperature sensor, or in the wiring that serves it.
At a glance
| Code | F8E5 |
|---|---|
| What it means | The oven could not execute the function; possible exhaust air temperature sensor or wiring problem. |
| What you can check | After a one-minute breaker reset, monitor the display for a minute. Confirm that the microwave operates. |
| When to call a technician | If F8E5 persists, schedule a service visit. No cleaning or inspection step exists for owners, so quote the full code and mention the breaker reset. |
How it compares
All three carry the same unable-to-execute sentence, but F8E5 is the one that names a temperature sensor.
A sensible reading
General background: an exhaust air sensor gauges how warm the outgoing air is. The article says nothing on how the microwave responds when that reading is wrong, and it never connects F8E5 with the vent door, so they are separate subjects. Questions about the vent door go to F7E9.
Power reset
- Turn off the circuit breaker(s) and wait for one minute.
- Turn them on.
- Monitor the display for a minute, looking for F8E5.
- Confirm that the microwave operates.
If F8E5 persists
What remains in the article is service. Owners are given no cleaning, inspection or part test. Quote the full code when you call and mention the breaker reset you carried out.
What to have ready
No symptom is documented for F8E5, so the code and the reset outcome are nearly all you can report. If you recall seeing it during start-up or mid-cycle, say so; a technician can still use that, though the article never requests it.
