Instead of telling you, i have question do you have any instructions on how to do the repair. It would have helped save time on the repair.

This job took longer then it should have, becasue I did not start right in the begining. I did figure it out quickly after the wrong start.

You were a big help in picking the right part to correct the problem. You should be able to help with the repair. Thank You

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.

This is not easy to do. I done it before to replace a broken window and it was a real bitch. I considered buying a new door rather then do it again.All I wanted to do was tighten two screws that hold the handle.
I used the advice found on your web site from a person who did it using quarters and putty knifes to remove the choke and the door insert. Sounded silly but it works like a charm. I advise anyone who needs to do this repair to use that info on your web site. It will save lots of frustration. Be sure to have plenty of quarters and a few pennies.

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.

Existing tabs on plastic vent grill had broken off

  • Customer: Roland from Kissimmee FL

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.

Microwave Turntable Won't Rotate

  • Customer: Steven from Sacramento CA

I turned off the power to the oven at the breaker. I then removed the side trim pieces by removing the screws located behind the lower oven door. I removed the plastic trim pieces above and below the microwave oven and removed the control panel and slid it into the opening above the microwave. I located the two screws securing the microwave into the frame and began sliding it out. I had to disconnect a small wiring harness and two wires from the microwave that were attached inside the opening above the microwave. The microwave section was the easily slid out, turned on it's side where the turntable motor was accessed by removing the access panel. I pulled the old motor, checked resistance and it matched the new motor. I then checked the old motor by applying 120V to it and it ran FINE! I thought I had the wrong part, but decided to install the new motor anyway. I did, secured the access panel and replaced the microwave in the frame. I reconnected the wires and secured the control panel and tested the microwave...and the turntable works!

Replacing the cracked door handle

  • Time to Complete: 1- 2 hours
  • Tools Required: Screw drivers

We had to take off the black inside frame of the door in order to get to the screws which held the handle on. Getting that piece off was a real challenge for fear of cracking the plastic around the edge of the door.....it wasn't very easy. Once we got that off, the rest of the repair was simple, and replacing the inside frame went very smoothly.

Replace Door Frame

  • Customer: Paul from Norman OK
  • Difficulty: Difficult
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers

Whirlpool advised that they did not have instructions to replace the door primarily because of liability issues. Without instructions I had to try and find an appliance service business to replace the door frame. Several were contacted and some indicated they would do it for $89.99 plus labor. Finally found one who would do the job for a total of $60. I would very likely have replaced the microwave since a new one would cost about $250; however, Whirlpool has changed specs and the new ones wouldn't fit the same space and work would be required to fit it to the space costing more. When I buy a new one it probably will be one that has a manual for assembly and a parts list.

The plastic screw brackets had broken on the original model.
