GMH3204XVQ0 Whirlpool Microwave - Instructions

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.

Looked up symptoms on parts select website. Ordered mag and diode. Very easy to take micro off the wall. Easily removed screws holding the skin on. Found diode. Really didn't need to replace it but since I had a new one (fairly cheap), just did so. Diode only installs one way. Can't botch it HOWEVER, MAKE SURE THE ONLY PART OF THE DIODE TO TOUCH THE GROUNDING POLE IS THE SCREW DOWN LEAD. IF THE OPPOSITE END LEAD, THAT WHICH IS THE PUSH ON TERMINAL, TOUCHES THE GROUNDING POLE, YOU'LL GET ARCHY SPARKY. The magnetron goes in very easy. Simply pay attention to how you removed it and reverse that process installing the new one. There are easy to use YouTube videos that show magnetron replacement. You can do this easily and save your microwave and $$ while doing so.

Easy, peasy!

Replaced the supports and rack.

Spouse just screwed in the new bulb and reinstalled the light cover plate with the two screws. Took under a minute. Works great.

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.

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!

It took me 15 minutes total - 5 minutes to clean the microwave, 1 minute to install three new parts, and 9 minutes to enjoy my celebratory glass of wine!

Opened door and put new plate in.

Placed order on Thursday evening and received Sat Am

I removed the microwave to install a back splash and found the support edge on the backplate had broken off and was missing. I searched for parts for the microwave and found them on PartsSelect.com. Easy to order, and was shipped promptly.

Once the part arrived, install was simple, lining up the existing holes. The only hard part was setting the microwave up on the bracket due to the weight and awkwardness of the microwave.

Overall a very simple repair.

used screw driver to pry up old part. lifted right off. line up drive couple drive push on. repair took less than 1 minute to repair. works like new
