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.

Replacement of hood light bulbs

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

With a phillips head screwdriver I removed the screws, which were screwed to the then non-existent grille, at the top of the grille holder, GENTLY popped the new grill into place and replaced the screws. It took about five minutes. As a housewife, I feel that doing these little repair jobs around the house saves my husband time and aggravation. It was all very simple, and I got the ordered part in two days. Fabulous!

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!!!)

The opening was very tight

It was supposed to be a very easy replacement, but when inserted the legs in the bottom openings, the legs at the top didn't enter the opening.If insert first the top legs then the bottom legs could not go in. Tried to put a little force when turning grill to enter the top legs with the screws support. Finally very carefully put first the top legs, entering horizontally, and then giving a little push (forcing) the bottom legs in. This was not supposed to be this way, because I could had brake the bottom legs clip.

The lady in the Nova Scotia call center should get all the credit for being able to identify the part I needed from only the very limited information I was able to give her. Employee of the month for her. She also had such a great can do attitude. Lawence Baier

Cracked handle

  • Difficulty: A Bit Difficult

Well, to get to the screws for the handle, the door "choke" had to be removed, which was difficult, until I read that you need a putty knife. But I had already tried to take the old one off, and it was brittle & cracked, so I also had to purchase the "choke"/frame. Once the parts arrived (within 3 days!), installing them was easy, but then I had a problem with the door. It wouldn't shut correctly, which made the microwave shut off intermittently during use. So I had to determine which of the latch catches had the sensor. (It was the top one.) I tried adjusting it without any disassembly, but it fell out & down inside the oven. So I figured out how to get that part of the oven open. I had to remove the upper grill and the touch panel. Once those were out, it was easy to retrieve the latch catch & install it correctly. I reassembled the oven, and now everything works fine. This oven was manufactured for Sears by Whirlpool over-14 years ago, and has been very reliable, so I'm not complaining. Interestingly, I looked at new microwaves and found a Maytag model (also made by Whirlpool) almost identical to the one I have. I examined it and found that the door, touch panel and grill are almost identical and use the same parts as mine!

Part Number: PS389799 Door Frame – Almond

Thank you very much for your excellent service. The door frame was delivered 24 hours after ordering it. I did find the installation tips wanting so here are some tips you can share with others.

Effort 30 minutes and is easy. I suggest a Phillips screwdriver, several regular screw drivers and a hot glue gun. Those replacing the door frame need to know that the glass protective panel does not come with the frame.

1. There are only 5 Phillips head screws involved.
2. To remove the old door, remove three screws on the side of the door.
3. Use several conventional screwdrivers inserted under the top of the frame to lift it above the tabs that hold the frame in place. The frame should be removed from the handle side first.
4. Once the frame is loose, closing the door allows for full removal of the old frame.
5. There is a protective glass window that must be removed from the old frame. This does not come with a replacement frame. It is held in place by a soft glue. Scrape it away from all 12 tabs.
6. To pull the glass out, pry with your hands on the large horizontal tabs. This should allow just enough space to slide the glass out.
7. Clean the door and glass before assembly.
8. Remove the two screws from the handle on the old frame and transfer the handle to the new frame.
9. Slide the glass into the frame. Use a hot glue gun sparingly along each of the 12 tabs to keep the glass tightly in place. (The glue is used after the glass is installed).
10. Place the new frame back onto the door and secure with three screws.

Orginal oven door had cracked

  • Customer: Elton from Lampasas TX

Door frame is like a box, It fits tightly over the rest of the door. On this door you would open the door and start sliding a tnin blade under the inside lip of the door and start very carefully prying up and outward until the door begins to come off. after you have removed the frame you can just pop the new frame in place. It is much easier than it looks.
