KitchenAid KHMC1857W Architect Series Microwave Hood Repair

Schedule Service(713) 903-2606

Most common issues on this model

  1. Vent fan noise or weak airflow from clogged filters
  2. Latch and hinge wear that interrupts cycles
  3. Interior lamp or cooktop light failure
  4. Control board and keypad trouble after years of use

The KHMC1857W belongs to the Architect series, a 30-inch hood combination with 1.8 cu. ft. of oven space and 1000 cooking watts. You may also see it listed as KHMC1857WBL, KHMC1857WSS or KHMC1857WWH. It hangs above the range, so the 300 CFM vent system works every time a burner is lit.

Most calls start at the fan. We pull the filters, clean the blower wheel and listen to the motor, since grease explains most weak airflow. Then we check the door latch and hinges, the lamps, and the keypad. The price is written down before we begin, and the repair carries a 30-day workmanship warranty.

Over a range, the oven and its vent share one housing, so we also check that the mounting screws are tight and the vent opening is clear. A unit that vibrates against the cabinet often sounds worse than it is.

KHMC1857WKHMC1857W questions
The fan in my KHMC1857W sounds louder than it used to. What causes that?

Grease on the filters and blower wheel is the usual cause, since the 300 CFM system moves a lot of kitchen air. We clean them, then check the motor bearings if the noise stays.

My KHMC1857W stops when I close the door firmly. Why?

A worn latch or hinge can leave the door misaligned with its safety switches. We inspect both, replace what is worn, and confirm the oven only runs with the door properly closed.

The cooktop light in my KHMC1857W went dark. Is that the bulb?

Sometimes, but a burned socket is common over a range because heat rises straight into it. We test the bulb and the socket together and replace the holder if it is discolored.
