KitchenAid Over-the-Range Microwave Code E11: gas sensor alert

What E11 means

On KitchenAid over-the-range microwave hood combinations such as the KMHS120ESS or KMLS311HSS, E11 says there may be a problem with the gas sensor, or the associated wiring. This sensor helps the microwave judge cooking by the vapors released. Without a good reading, sensor cooking programs may stop or show the code. Gas here refers to cooking vapor, not natural gas from your range.

Common causes of E11

Gas sensor not reading cooking vapor
Wiring to the sensor loose
Moisture or grease affecting the sensor area

✓ One safe check you can try

1. Press Cancel. 2. Wipe the cavity walls and ceiling. 3. Leave the door open for ten minutes so the cavity dries. 4. Restart with a timed program. 5. If E11 comes back, call us. If you ever smell natural gas from your range, leave the house and call the gas utility from outside.

! Why to stop there

The sensor lives in the cabinet above your range, and access is tight
We test it before ordering a part
A written price is quoted first, with a 30-day warranty

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E11E11 questions

Does E11 mean a gas leak?

No. The gas sensor in a microwave detects cooking vapors, not household gas. If you smell gas, leave and call the utility from outside.

Can I use the microwave with E11?

Timed cooking may still work, but sensor programs likely will not. Use manual times until it has been checked.

What about E12?

E12 uses nearly the same wording but says there is a problem, rather than may be. We treat both as a gas sensor check.
