KitchenAid KHMS155L Over-the-Range Microwave Repair

Most common issues on this model

  1. Cracked or broken door handle
  2. Vent grille that keeps working loose or dropping off
  3. Oven that powers up or runs by itself, which should be inspected promptly
  4. Control board wear after many years of service

The KHMS155L is a 30-inch microwave hood combination that hangs over the range, with 1.5 cu. ft. of cooking space and 1000 watts. It is also sold as KHMS155LSS, KHMS155LBL and KHMS155LWH. Mounted above the burners, it sees steam and cooking oil daily, and that is what ages it.

The door handle is the part owners notice first, since plastic that has been pulled thousands of times eventually cracks. The vent grille is the other regular visitor on our list: its mounting tabs loosen and the grille drops. If your KHMS155L ever starts or runs without being asked, unplug it and call us. That behavior points to the control board or a door switch, and we will not leave it in use.

We give you a written price before any work and stand behind it with a 30-day workmanship warranty.

KHMS155LKHMS155L questions
The door handle on my KHMS155L cracked. Can I tape it and keep going?

We would not. A weak handle can break mid-pull and leave the latch out of line. A new handle is a quick swap, and we check the door seal and latch while the door is open.

The vent grille of my KHMS155L keeps falling off. What fixes it?

The mounting tabs and screws have usually worn out. We refit the grille with fresh hardware, and confirm the fan inside is spinning freely so airflow over the range works as it should.

My KHMS155L started running on its own. Is that dangerous?

It needs prompt attention. Unplug the oven or switch off its breaker. We test the control board and door switches to find where the false start comes from, then report what is needed before we repair.
