I ordered another one and placed it inside the microwave. It works and fits perfectly. I received the order exactly as scheduled.

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.

First remove three screws on the handel side of the door,then use a thin blade [putty knife or butter knife to seperate the plastic colored face from the door very gently . You must pry up to seperate the catches of the door panel from the door. Work your way back to hinge side of door. Remove the handel from the panel [2 screws] then remove the protective outter glass,push back on clips and lift glass out. Reverse the proceedure the door panel snaps back on to the door easily

Removed two screws to that held the old bracket. Installed new part and replaced the screws. Very simple. About 10 minutes. The part cost about $38.00. A repairman charged my neighbor 100 + dollars for the part and plus installation for the exact same thing. I highly recommend Partselect.

Rep knew exactly what I needed when I described where the part should go on my microwave - price great - shipping great - installed in seconds. Thank you!

Unscrewed three screws and used putty knife to pry door cover off unscrew door handle put on new face plate and redo the three screws and clip back on oh you have to unclip the glass part and put on to the new face plate before putting on new door front to microwave

Looked up the Whirlpool Co. and ordered the part. It was quite simple. Arrived in 2 days and I simply placed it in the microware. It was very very easy!

I loosened the 2 screws at the top, removed the broken-off pieces of the old part, then easily placed the new part and tightened the screws.

The whole process was so easy! It was easy to order the part. It came directly to the house in just a few days.

Thanks.

Thank you. The part was easy to find on your web site. The order came within 3 working days and the part replaced

I removed the two screws on the side. Took a putty knife and gently pryed it away from the rest of the door. I took the handle off the old door and put it on the new door. I took the glass and the plastic frame that holds it on off the old door and put it in the new door, I snapped the new door back on and relaced the screws.

Remove the two screws to the plastic vent strip at the top of the unit. That exposes a metal cover (upper right) held in place by two more screws. (Found that removing the screw holding the key panel in place and moving that out of the way made for more work room) Remove the metal cover. The HV diode (visible) on one end is secured to the chassis by a screw. The other end is fitted to the HV capacitor. So unscrew one end and pull the HV diode off the capacitor. The replacement fits on like the old one came off. Very simple repair. But it would be safe to short the capacitor terminals to the chassis first. Noticed that it appeared the sparking was caused by the HV diode's outer casing being worn by the asbestos covered wire next to it and laying against it. I made sure the two were not touching, before putting the covers back on. Also, the problem started with an occasional spark when the MW started. It quickly deteriorated to a full, non-stop electrical sparking. You can hear it, smell it, and see it through the top vent. You don't need to remove unit to work on it.

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.

After removing the over-the-range unit (no small feat!) I had to figure out how to open the case (good puzzle!). Capacitor had already discharged, so it was very easy to reach in, pop the old fuse and install the new one! As per your advice, I found out I was a "28%-er"! Upon re-installation, the microwave "sprang to life"!! Thanks, "Part Select"!! I was already shopping around for a new machine! (Now if you could only tell me an easier way to re-mount this heavy beast over the stove!!!)
