F4E9 refers to the Smart Pop control and its wiring.
Model compatibility: KitchenAid reuses codes across series and model years, so F4E9 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Possible problem with the Smart Pop control or its wiring.
F4E9 and the Smart Pop control
KitchenAid’s help for the over-the-range microwave ties F4E9 to the Smart Pop control or its wiring. No other code on the microwave list names this feature.
How much the page explains
The feature name hints at popcorn, and the microwave help index does list a popcorn article called “Popcorn Results” as well as an “AccuPop Fail” entry. Still, the F4E9 article gives no description of the control and says nothing about how it connects to those pages.
Reset steps
Switch the microwave’s circuit breaker(s) off and keep them off for a minute.
Switch them on again.
Look at the display for one minute for any return of F4E9.
Run the microwave to check that it operates.
Results
Code gone: the article ends there.
Code back: the article suggests booking service.
No middle step exists for owners.
Place in the F4 series
Not every F4 code is a thermistor code. F4E1 and F4E4 name thermistors, whereas F4E9 concerns a control feature. The final two characters decide the meaning, so be sure you have copied the whole code before searching or phoning.
Preparing to book
Record the complete code, F4E9, and the date it first showed up. The article does not request this, but a technician can use it. Covers stay closed, and the reset happens at the breaker only.
