SOURCE: MICRO WAVE RUNS BUT IT DOES NOT HEAT
Generally, the most common causes of a failure to heat are:
- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part such as high-voltage rectifier diode
If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and

Chances are you have a shorted high voltage rectifier diode or a bad magnetron, but it may be a bad high voltage transformer.
There should
be a "mini-manual" hidden inside the unit behind the control panel or
hidden on the left side behind the grille, which isvery helpful when troubleshooting & testing.
At our site, we have a video showing how to remove a typical over the range control panel assembly in under 5 minutes.

These models use halogen
lamps. You must not touch halogen types with your bare skin, as the
oils
will shorten the bulb life.
You should be able to
get one from a home center or local appliance parts store.
If you order it online (from the link above) it is part # 4375348.

SOURCE: Kitchen Aid (KA) Over stove Micro - vent grill plastic brackets
My grill has also fallen off twice. It usually results in the tabs breaking off. My solution has been to add tiny (1/2" x 1") shims in the slots where the tabs have broken. Look carefully. There are two tiny channels. I wedged the wood in and then reattached the grill using sheet metal screws in the same screw holes. It won't come down again. In three years since doing the kitchen with all KA appliances we have replaced the grill once. We had the stove removed and replaced by the appliance company at no charge after 4 months. We had our ice maker replaced out of warranty. I would never recommend KA appliances to anyone. The quality is absolutely terrible.
