KitchenAid KCMC1575B Microwave Hood Service

If your KCMC1575B hangs above a cooktop, it has two jobs, and the exhaust fan carries the heavier load. The KCMC1575BSS version, with plate code KCMC1575BSS0, is the one on record.
If you notice the fan has become noisy or the steam from a pot no longer disappears, the usual reason is grease. We remove the filters, wipe the plenum, and turn the blower by hand to feel for roughness. A seized or rubbing bearing gets a new motor. Spent charcoal filters are replaced as well.
The microwave side gets its own test with a water load, and the keypad and board are checked while the cover is off. You see a written price before we order anything, and our 30-day workmanship warranty applies.
The grease filter is probably loaded, or the fan runs slow. We clean the filter, change the charcoal filter if your unit recirculates, and test the blower speed.
They share the cabinet and the control, but have separate motors. A fan problem rarely affects heating, so we test each side on its own.
It is a build revision of the KCMC1575BSS version. Switches, boards and fan parts can differ between revisions, so we read the plate in full and order the part that matches your particular build.
