KitchenAid KMHS120E 30-Inch Over-the-Range Microwave Repair

Schedule Service(713) 903-2606
KitchenAid microwave

Most common issues on this model

  1. Hood motor that hums loudly or moves less air
  2. Sensor Cook ending too soon or too late with some dishes
  3. Latch switch that stops registering after constant use
  4. Halogen lights over the cooktop that will not stay on

The KMHS120E is a 30-inch over-the-range microwave with 2.0 cu. ft. inside and 1000 watts of cooking power. It is also sold as KMHS120ESS. Its 400 CFM ventilation runs at three speeds, and because it is mounted directly above the burners, the fan and the cooktop lights are the parts that get the heaviest use.

If the hood seems to move less air than it did, we check the filters first and then the blower wheel and motor. A loud rumble at the highest speed is typically grease or a worn bearing. The halogen cooktop lights are another regular call, and we test the sockets as well as the bulbs. For cooking complaints, such as Sensor Cook finishing too early or too late, we confirm the steam sensor path is clear and the door latch switch is closing fully, since a marginal switch affects sensing cycles.

Written price before any work, and a 30-day workmanship warranty after.

KMHS120EKMHS120E questions
The fan on my KMHS120E seems weaker than before. What do you check?

We begin with the grease filters, then the blower wheel and motor. Buildup often cuts airflow at all three speeds. We clean what we can and quote a motor only if noise or slow speed remains.

Sensor Cook on my KMHS120E under- or overcooks food. Can that be repaired?

Yes. We confirm the vent path is clear, test the sensor circuit, and check that the door latch switch closes fully, since each affects how the oven judges doneness.

The cooktop lights in my KMHS120E stay dark after a new bulb. Why?

The halogen socket may be burned or the connection loose. We test the voltage at the socket and replace the holder when it shows heat damage, then verify the light holds.
