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

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!

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.

followed the directions by one of your other DIY'ers and his description was invaluable, without it i would not have been able to replace the parts. just follow his instructions and you'll be fine. don't remember his name but he described inserting butter knives around the bracket to allow it to pop lose.

After researching online, I found that I needed the turntable drive coupling, part#PS993087. when I went to your site it showed the same part but the part number had changed but said it would fit my microwave. Well, I was really surprised and happy when the part I received 3 days after I placed the order, with normal shipping,fit perfectly and now my turn table in my microwave works. I have marked this site a a favorite and will use it I'm sure soon. Being a single women and having to figure out how to fix the things on a small buget, I'm learning a lot and have a lot of respect for men that know how to do all the repair stuff. Thanks so much, I have been able to mark this off my list of things to fix. Have a nice day. Cj- age, 58

Loud buzzing noise and no heat.

  • Customer: Charles R from Libertyville IL
  • Difficulty: Difficult
  • Time to Complete: More than 2 hours
  • Tools Required: Nutdriver, Pliers, Screw drivers, Socket set, Wrench set, Wrench(Adjustable)

PartSelect website indicated replacing the high voltage power supply diode is the solution for "no heat" 99% of the time, but the diode was OK. There is more info at the website concerning the case of "loud buzzing and no heat" indicating the magnetron needs to be replaced. As an electrical engineer with knowledge of microwave components, this was also my best guess. However, getting to the magnetron is not the easiest job, but it's not impossible. You also have to be careful to bleed off any charge stored on the high voltage power supply capacitor. Luckily, I found my KitchenAid service manual tucked away inside the unit since I couldn't find it online.

I called the repair/parts number to make sure I had correct parts and the young lady instructed me as to the size of the serving tray; within 48 hours we had the VERY carefully wrapped carton opened and back in the microwave, working perfectly. Thank you. We'll recommend you to our friends!
