YKHMS1850SS1 KitchenAid Microwave - Instructions

This should be a 1 minute repair. However, there are a few issues. First, make sure you order the correct bulb. Mine is a halogen push in bulb, but the parts list showed a screw in bulb.
Remove power from the unit OR be sure that the light is turned off with the push switch.. The display will show the status as you rotate through the dim levels.
There is a single Phillips head screw holding the cover on the underside of the over stove microwave. carefully remove it. When loose the panel will drop down and you will find the old bulb in the center of the front of the opening. Remove the bulb. Now the important part. Carefully unpack the new bulb being careful to not touch the glass with your bare hands or fingers. Then insert the bulb into the socket.
If you unplugged the unit then plug it back in and push the switch to check that the new bulb works and is in the socket, then turn it back off.
Carefully lift the cover back into position and replace the screw. This is the hard part as you are working upside down and can't really see when it is lined up properly. When you have the screw back in and tight you are done. Press the light switch to enjoy your lit up stove again and put your tools away.
If you get your fingers on the glass bulb then clean it off with some rubbing alcohol and a paper towel to remove any finger oils before you put the cover back in place. Finger oils can boil with the heat of the lit bulb and cause the glass to explode. This holds true for any halogen bulb.

Loosened but did not remove screws that held up microwave over range,removed grill on top by loosening screws that held grill in place.removed small mesh grill on right side of microwave, this gave me access to capacitor ,diode is connected from one lead of capacitor to a metal plate ground,Disccarged capacitor to ground by shorting terminals to ground using a thick insulated screwdriver.Since the diode was screwed to the top of the metal plate I cut it out with a pair of side cutters .I then connected the new diode to the capacitor with my long nose pliers and groonded the other end to a more accessible part of the metal grounding plate.I then replaced all parts in reverse order.Works like a charm.
