KitchenAid Over-the-Range Microwave Code E22: temperature reading alert

What E22 means

KitchenAid over-the-range microwaves like the KMHS120ESS, KMHC319ESS and KMLS311HSS can show E22 when the thermal sensor, the appliance control board, or the wiring may have a problem. A temperature sensor tells the control how hot the cavity or hood area is. Lose that and the microwave will usually stop and wait for a reset.

Common causes of E22

Thermal sensor failing
Control board misreading the sensor
Sensor wiring damaged or loose

✓ One safe check you can try

1. Cancel the program. 2. Open the door and let the unit rest for ten minutes. 3. Check that the air vents are free of grease. 4. Pull the plug for a minute and reconnect. 5. If E22 reappears, call us.

! Why to stop there

The part is above your stove, where heat and grease are present
Testing is needed to pick between the sensor and the board
Price is in writing first, and a 30-day workmanship warranty follows

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.

E22E22 questions

Why is the sensor close to the stove heat?

Over-the-range microwaves sit above cooking surfaces, so they also monitor temperature to protect themselves. Heavy use can stress the sensor.

Can steam from the stove trigger E22?

It can influence a reading, but a lasting code means the sensor or board needs a check.

Should I stop cooking on the range below?

Your range is unaffected. The code concerns only the microwave.
