KitchenAid KHMS105E Microwave Hood Repair

The KHMS105E hangs above the cooktop as an over-the-range microwave oven and hood, with a 2-speed exhaust system, so it takes in every splash and plume the stove produces. Several endings are on record: the KHMS105EAL, KHMS105EBL, KHMS105ESB and KHMS105EWH.
Its two exhaust speeds give us a quick test. If the low speed hums but the high speed is loud and weak, the blower wheel is likely coated. If one speed does nothing, the switch or the motor winding is suspect. We pull the filters, wipe the plenum, and time both speeds.
The microwave side is tested separately with a water load, and the board is checked for grease damage. Pricing comes in writing first, and a 30-day workmanship warranty covers the repair.
Either the speed switch or one winding of the fan motor has failed. We test both with a meter to decide which part to replace.
That depends on how it was installed. We check on the visit, and we replace the charcoal filter only if the hood recirculates air into the kitchen. If it vents outdoors, the grease screen is the filter that matters.
Over time, grease works past a loaded filter into the control area and the cooling path, which stresses the board and the fan motor. Clean filters protect everything behind them, including the microwave side.
