I broke the inside oven door glass while cleaning it

  • Customer: Guy from Little Rock, AR
  • Difficulty: Difficult
  • Time to Complete: More than 2 hours
  • Tools Required: Pliers, Screw drivers, Wrench set
  • 4 of 4 people found this instruction helpful
The exact part for this oven is no longer available. I purchased one hat was close in size, but larger than the original. Upper and lower brackets hold the glass in place, so length was not a problem but height was. I removed the upper brackets, re-shaped them with the vise, a hammer and metal shears. The glass would now sit inside the bracket where the screws also went. I had to be quite careful the screws did not shatter the new glass.

The hardest part was aligning the 4 holes for the top brackets. Since 2 holes were on one piece of the door, and 2 were on the other (holding the glass sandwiched between) precision was critical. Also the screw length was critical because the glass now sat in a area where it could come in contact with the screws. (I know - pictures would be most helpful, and I didn't take any.)

Using tape and lots of patience, I got the holes aligned. I covered the old holes inside the oven door with spare screws. I filed down the points of the sheet metal screws so that, if they contacted the glass, they would not be pointed.

Once everything was reassembled, I turned the oven on high for about 1/2 hour to ensure the heated metal and glass all played nicely together. We've had no problems in the month since the repair.

Taking the door apart.

This was more difficult than anticipated - probably because I'd never done it before. Once I got the door off (I didn't have the proper pins and used nails but didn't realize they had to be headless) I found all the screws, which were relatively easy to take out. I was surprised that the thermal door glass was obscured by two other panes of glass. It took more disassembly than anticipated and a few false starts when reassembling, but all in all it got done. I was happy that a job that would have cost probably $300 or more ended up getting done for $40 plus my labor - which isn't worth much these days. I'd certaily do it again.

Door spring broke (spring lightens the door when opening/closing)

Just had to remove the screws holding the outer part of the door on (didn't have to take off the entire door). Using the other door spring (most models have two that cross) as an example, the new spring was fairly easy to place. Only problem is that the new spring was made from a smaller gauge metal and is not nearly as strong as the original, making the door feel heavier when opening/closing than before. The difference with and without the 2nd spring is barely noticeable. Had I known that they were making the parts cheaper now, I would'nt have bothered fixing it at all.

Broken inside view glass

  • Customer: Michael from Costa Mesa, CA
  • Difficulty: Really Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers
  • 4 of 4 people found this instruction helpful
Removed 4 screws top and bottom of the outer door panel. Remove outer door, then the two inner panes of glass. You are then able to remove the broken inner glass. Carefully slide the new inner glass into place, being careful not to tear the insulation. Once new inner glass is in place carefully replace the two inner glass panes and secure the screws. Replace the outer door and the top and bottom screws and that's it!

This is a small halogen light bulb for the microwave. This is the third time it has had to be replaced.

  • Customer: Robert from LAGUNA VISTA, TX
  • Difficulty: Very Difficult
  • Time to Complete: More than 2 hours
  • Tools Required: Nutdriver, Pliers, Screw drivers, Socket set, Wrench (Adjustable), Wrench set

This is the third time that the bulb went out.It took two Sears service technitions to remove the entire appliance out of the cabinet. The entire top has to be removed and the insolation has to be pulled back to get to the electrical wire. I am waiting for an appointment to get Sears to do it again. The door springs have broken and you have to make sure the door is closed before walking away. It has a heavy glass and the weight is pretty heavy. Robert.

oven wouldn't heat after self-cleaning the oven

  • Tools Required: Screw drivers

The website and diagram of my oven helped me know exactly what was wrong and where to locate the problem. I simply removed the oven door and the trim, pulled the oven out of the wall. After removing the back panel I located the part and put in the new part. Then reversed the procedure.

Microwave Turntable Won't Rotate

  • Customer: Steven from Sacramento, CA
  • Difficulty: A Bit Difficult
  • Time to Complete: 30 - 60 mins
  • Tools Required: Screw drivers
  • 6 of 12 people found this instruction helpful
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!

Broken Inner Glass on Oven Door by a Grandmother Who Should Know Better!

  • Customer: Diane from Citrus Heights, CA
  • Difficulty: A Bit Difficult
  • Time to Complete: 1- 2 hours
  • Tools Required: Screw drivers
  • 3 of 5 people found this instruction helpful
After reading all the other entries, I decided that I could do this! My first hurdle was getting the oven door off the hinges. Mine were not like any of the others described. My son-in-law looked at them and couldn't figure them out. So, I found the original installation instructions and, lo and behold, they said to flip the lever (one finger operation) in each of the rectangular holes holding the door onto the oven and then lift up until the door comes off. I did it, and it did! Boy, is it heavy! From there I just followed everyone else's instruction about undoing the screws, washing the glass panels, lining up the screw holes to get it back together, etc. One thing that took me longer was that the steel panel needs to go back the way it came out, not flipped! When I washed the glass panel it held, I put it down wrong and then "installed" it backwards. Luckily, I have a double oven and looked at the other one to see what was holding up the re-assembly! I'm glad that one of the others mentioned that the glass on the "bottom", the one that broke, isn't held in my screws or steel plates -- nothing, so I wasn't surprised when I got to it and it was "floating" on the insulation. My white insulation was like a fine fiberglass and was easy to stuff back in around the rim of the new glass. Took me a little over one hour. So, no more wet rags on hot glass (you'd think after living 72 years that I would remember this!) The glass fit perfectly and my husband would have been proud of me -- that I tackled a job that he usually handled, and that I saved over $200 for a couple of hours of labor and travel time.

Everything worked perfectly---thanks to the suggestion of your call center agent. She suggested that since the replacement door handles were no longer available, I should consider repainting them--it worked like a charm. Please tell her she was a life saver. We rent that house in Fl and my returning tenants had complained about the discoloring refer handles. Thank you
