MH8150XJT0 Whirlpool Microwave - Instructions

the burn thru was probably because stirrer motor was not turning, Unplug the microwave .freed the motor up bu manually turning. temporary fix. The cover is held up with small push pin clips. Just pry the cover off with a screw driver or other flat tool. Scrape offf the old silicone. There are two covers in the Kit. you just need 1. Remove the old clips for the roof of the microwave, put a bead of silicone on the new cover where the old was and secure the new cover with the push pins into the clips .

Removed screws holding the broken grill tabs with a phillips screwdriver
Removed broken grill and all broken tabs that fell into the vent area
Cleaned area where the new grill was to be placed
Inserted new grill onto the appropriate tabs and tightened the screws

BE CAREFUL as the tabs on the grill are thin and fragile when you insert the new grill don't force it into the slots, I used a knife as a way to slide the grill into place.

removed the two screws, removed all of the broken tab pieces, replaced with new grill, put the two screws back.,....DONE Easy as pie

After reading other entries, I have determined this is a problem with most grills on the whirlpool microwaves. Defective material ..becomes brittle and crumbles.

It was a bit awkward because the microwave is mounted over my stove. I had to twist around and install the bulb and then replace the cover. It was a bit uncomfortable. It took me about 10 minutes to complete.

Removed the microwave from above the oven by loosening the two screws above the microwave. As the unit tilted outward lifted up and the whole unit came out all the time feeding the power cord through the cutout for the power cord. After it was out removed the cover and identified the capacitor and made sure it was discharged and removed and replaced the diode. tested before reinstalling and it heated up just fine. Reversed order and reinstalled . Very easy job maybe a second hand to help fish the power cord when installing and removing.

Removed screws and broken door frame. Removed glass cleaned and installed in new frame. Snaped new frame in place and replaced screws.

Purchase a new door frame it arrived and I unwrapped it. I remove 3 srews from the end of the door and pryed up and the old frame came off. Be careful to watch the glass does not fall out. Remove handle by removing 2 screws and put on new door frame. Remove glass and put in new door frame. Then I carefully pressed it back on the inside door frame and replaced screws. Complete, very easy.

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.

Removed 2 screws from top of microwave. Place new grill in place. Replaced 2 screws that were removed. What was wonderful is I ordered the part around 3 pm on a Friday. The part arrived at 9AM the next day and that was without requesting special shipment.

Unscrewed the remaining pieces of bracket slipped in new vent cover and attached with the two screws. Very easy since the web site showed where the vent attached. I saved over $60.00 doing this repair myself!

I didn't have to remove the old cover since it cracked and fell off the microwave already. I simply snapped in the new vent cover, screwed in the 2 screws and I was done. Super easy.

I removed the two screws and took off the old grill. Snapped the new grill in place and replaced the screws. This model was not shown on the list but the part fit just fine. The part arrived in 2 days! I ordered the white one and at first didn't think it matched .. maybe my microwave was bisque or almond .. but after 15 minutes of scrubbing I realized it was white but just real dirty .. lol. Now the door opens without the grill falling off. Easy fix.

Take off top facing over microwave using screwdriver also protection plate for diode and capaitor. Disconnect diode from frame, bracket to capacitor then remove, disconnect wires leaving diode on capacitor for right connection, replace, rewire done.

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.

-leave door attached to microwave.

-remove three phillps screws from end of door next to handle.

-use two flathead screw drivers to pry apart the outside cover and unsnap the two sections of the door. Start in the top middle.
