Microwave worked perfectly but would no longer heat.
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.
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.
Dropped the glass cooking tray and it broke in half
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!
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!!!)
It's a simple repair but costly. Just open the door remove the three screws on the side of door. Now use a small screw driver or metal putty knife to remove the chooker collar around the door " be careful this can easly be broken". Okay now the metal inner door is easier to remove if you slightly bend the tabs up around the door. Look carefully you should be able to see where they catch. Once you do that carefully seperate the outter door cover. Careful sometimes it will pop right out and fall. Please no more further repairs needed. Just screw in the new handle push tabs back out on the metal inner door then snap everything back together and reinstall the three screws.
Broken handle (top of the handle actually broke off the screw)
After taking the three screws out of the side of the door, I actually had to get help from my Dad who came over and was able to pry the top corner of the door out of the casing. I was afraid I was going to break the door. Once he got the door pried apart, I was able to replace the handle, clean the entire door and quickly snap it back into place and then replaced the screws.
We took a chance on the less expensive black Whirlpool vent grille as I found online that it would fit our stainless steel Kitchenaid microwave. My husband was able to pry the stainless cover off the broken grille and snap it onto the new black one. Then just screw in the top screws to secure. We are very happy with the stainless/black of the new setup. It goes very well with the stainless/black of the cooktop and oven.
Very easy to replace. A short ladder provides easy access to two small Phillips screws on the top of the existing grill. Remove and keep these screws to re-use. Remove old cover and discard. Fit tabs on the bottom of the new cover into position on microwave and press entire cover securely in place matching the screw holes to the existing microwave. Replace small Phillips screws securely. Step back and admire your microwave!
