KMBS104ESS00 KitchenAid Microwave - Instructions

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.

Ordered a new one, put it in place in less than one minute.

Remove “over the stove” unit. Remove unit shell case. Unscrew and disconnect diode. Replace diode. Re-assemble. Put unit back in place.

Part arrived in timely manner and placed it in microwave oven.

Set the new one inside the microwave

PartSelect website indicated replacing the high voltage power supply diode is the solution for "no heat" 99% of the time, but the diode was OK. There is more info at the website concerning the case of "loud buzzing and no heat" indicating the magnetron needs to be replaced. As an electrical engineer with knowledge of microwave components, this was also my best guess. However, getting to the magnetron is not the easiest job, but it's not impossible. You also have to be careful to bleed off any charge stored on the high voltage power supply capacitor. Luckily, I found my KitchenAid service manual tucked away inside the unit since I couldn't find it online.

Fool proof.

Just put it in

I put the tray in the microwave???? Pretty easy.

EASILY REMOVED GLASS COVER INSIDE OVEN AND REMOVED SMALL HALOGEN LIGHT BULB.
RECEIVED REPLACED WITHIN TWO DAYS OF ORDER AND REPLACED BULB AND GLASS COVER IN ABOUT 10 MINUTES.
MOST DIFFICULTY WAS HAVING TO BEND DOWN TO REACH INSIDE OF OVEN TO LOCATE POSITION TO INSERT BULB.

We had to remove screws from the vent covers above and below the microwave, then there were 2 screws (one on each side) that attached the microwave to the oven. Once all of the screws were removed we had to pull the microwave out. Then we pulled the light cord out, removed the burnt out light and installed the new one. Then reversed the steps.

Replaced the glass tray

found the part no. and ordered it. it was delivered fast and efficient.
tracking was also helpful.
thanks

Easily replaced after received the product from Part Select. Very satisfied.

I took the new tray out of the box and placed it in the microwave oven.. No tools needed.
