MMV4207JK00 Maytag Microwave - Instructions

Put s pot under were you take the screw out.If you drop it you can get it 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.

I measured. I leveled. I mounted hanging bracket and here's where it got tricky because you need two people to raise the microwave into position. I'd stack 2x4's In the back by the wall. I'd stackem in the front on the cabinet top then raise the back and add more. You get it front back front back until it's high enough to snag the bracket. Holes pre drilled raise it on up tighten bolts and poof you're done!! I did loosen the screws that pull the cabinets together and the bottom screw that holes the cabinet on one side. It didn't seem like it needed it the way it slipped in but maybe it slipped in because I did it. Only takes a minute. Use a minute here save an hour there. Go do it! Times a wastin!!

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.

Really easy for a 75-year old female; just spent more time reading the online manual than actually installing the light bulbs to find out where to access the light bulbs.

Piece of cake. One screw to release the dropdown light diffuser. Just remember, the you're screwing the new bulb in from a reverse perspective. Also this site sends the correct part the first time.

mounted bracket, case closed.

Remove “over the stove” unit. Remove unit shell case. Unscrew and disconnect diode. Replace diode. Re-assemble. Put unit back in place.

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.

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.

screwed in new bulb

I ordered a new one then put the new one in the microwave. Easiest fix ever!

I removed the broken tray and ring-turn and replaced it with the new
Service was fantastic, parts were ordered one day and received the next
