Easy, peasy!

Placed Grill and tightened screws. It was trivial and the part was perfect.

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.

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!

I removed three screws and then "gently" removed the front door plastic panel. Two more screws were all that was required to remove the broken door handle and replace it. You DO have to BE CAREFUL in removing the plastic panel. It "snaps" on and must be "snapped" off. If you are not careful you could easily break the panel and have to purchase a much more expensive part. If you are careful it is easy and takes only a few minutes.

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!!!)

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!

Simply removed two screws to remove the old vent grille and replaced it with the new grille. I was also very pleased with the assistance I received from the service rep. I had ordered the wrong grille. I called the PartSelect help number and the rep walked me through the product return process, then found the correct part and ordered it. I had the replace 3 - 4 days later. The rep was very polite and patient during the whole process.

easy to replace, just the same as cleaning the turntable and placing back in the micorwave;

It took me time to remove the parts and suss out the issue, but the repair itself was EASY. A wire ribbon connected to the circuit board had gone bad. One Phillips head screwdriver, 7 screws, to get at the old one, pull it out, replace it with the newly ordered part. NO PROBLEM. Ladies, you can do IT!! You have the power!

Unplug appliance. Remove total of 7 phillips screws from sides and front of bottom panel . Panel front drops down, remove one socket screw and socket. Now have access for lineman' s pliers to unscrew bulb base. Reinstall socket, replace bulb and 7 panel screws. Restore power.

Didn't realize this part had two tabs with reinforced screwholes in it. Those obviously had snapped off at some time in the distant past, and I had always removed the grille for cleaning carefully and washed it by hand and replaced it. The clean freak moved in and took this out WEEKLY and all the other tabs were eventually cracked and made the grille unusable; it kept rattling and falling out. When I got the replacement I noticed the broken tabs and replaced the item in a few minutes after removing the debris of five or six tabs and finding a Philips head screwdriver for the apparent screws (in fine shape, they were!) and tab remnants. Good fit, looks like new. Now hopefully the clean freak won't find my screwdriver next week.

Whirlpool Model# MH1150XMS-0 purchased in 2004. I called Whirlpool and they suggested a new microwave. No big surprise - being the thrifty person that I am I wasn’t taking this for an answer. I figured if I had to purchase a new microwave what was $35.22 (part# PS373828 + shipping) if it worked.

I replaced the latch on the microwave door. Once the latch was replaced. I also took this time to make sure that the microwave door was in alignment. Thereafter, I had to adjust the door interlock switch behind the microwave console panel to recognize the microwave being closed. Yes, gaining access to all these areas was a bit difficult but have patience. TADA!!!....microwave is working. #girlsrock
