MH2175XSQ4 Whirlpool Microwave - Instructions

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.

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!

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

Unplug the microwave. Then remove the six screws that hold the lower panel which has the light bulb cover and a couple of vent filters. The light bulb sockets are on a fixture that is connected by a quick connect electrical connector. Disconnect that and the whole panel is free to access the bulbs. My bulbs were very fragile and trying to twist them out resulted in the glass twisitng loose with the base still in the sockets. I needed to use a needle nose pliers to remove the bases and then I replaced the bulbs and put every thing back together

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.

Took out turntable and swapped out old one with a new bright and shiny
New one, ring that is. It was easy using the part from parts select
Thanks

First, we had to clean up all the interior surfaces, which was just cleaning. There was no internal damage. Then, just setting the center connector, rotary rollers and glass plate. Simple

Took microwave off the mount, removed all the outer covers except the face, used metal screwdriver to short the big capacitor to keep from being shocked, removed magnetron and replaced with new part. Put back together, hung on wall, and finished. I used a youtube video and it turned into a very simple fix.

Removed two Phillips head screws, installed the new Vent Grill, and carefully reinstalled the old screws, being sure not to over tighten them.

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
Very Pleased with Parts Select replacement parts

I had to cut the leads on the thermostat to enable the wire terminal clips to fit on the leads. Not hard at all when the right tools are available. Care must be used because the leads are subject to being damaged. “ Hold leads with narrow needle nose pliers while cutting!

Removed the face plate above the door (2 Phillips screws.) Removed existing filter and replaced with the new one purchased. Reinstalled the face plate.

I was sent the wrong fuse by you. I had to procure a fuse in another manner. Very disappointing. The repair was simple. It just took longer because of the failure to send the correct fuse.
