Oven stopped heating after attempting a self cleaning cycle. Problem turned out to be failed thermal fuse component. This is an easy repair and well worth the attempt given the replacement cost of the oven.

First step was to locate and shut off the two circuit breakers supplying power to the oven. Then I locked the panel to ensure someone didnt re-engage the breakers while I was working on the unit. (Lock out / Tag out).

Second step was sliding the oven out of the cabinet - this unit is located below a cooking top and was just the perfect height to allow a furniture dolly to be used to support the oven as I slid it out.

The unit is 'hard wired' (i.e. no power plug) so it can only be pulled out so far from the cabinet, but there was sufficient reach to allow access to and removal of the sheet metal cover at the rear of the oven to expose the thermal fuse and the read wiring. I proceeded with care, assuming the power was still on and once the terminals of the thermal fuse were exposed I performed a voltage measurement to ground on each side of the fuse to ensure power was in fact off.

Then I used an insulated pliers to gently remove the wire harness at each side of the fuse, and once the wires were removed I performed a continuity check of the suspect fuse, and confirmed it was an open circuit (i.e. failed).

Removal of two more screws allowed the fuse to be removed and the new fuse was installed, reversing the procedure.

This was followed by replacement of the rear sheet metal and finally sliding the oven back into its place in the cabinet using the furniture dolly. This is a single oven but still very heavy and has some sharp sheet metal edges likely to cause cuts if not handled with care so the dolly and a second set of hands (and good gloves) are nice to have.

Finally, after inspecting the oven door gasket and other air vents around the outside of the oven to identify suspect causes of the overheating event that tripped the fuse, the air vents above and below and within the door were cleared of dust-bunnies and other debris that had collected, possibly causing interference with the air flow that cools the area in between the oven and the cabinet. This blockage may have been the root cause of the fuse failure - i.e. the air did get too hot back there and had the fuse not tripped it would have been dangerous. The door gasket looked fine although its also an easy replacement and does not require oven removal.

The new part fit perfectly - it was a different design than the original part that shipped with the oven but appears to function perfectly so no complaints. The trip temperature is identical to the OEM part based upon the nomenclature on the back of the OEM and the replacement fuse part.

Unlocked the power panel and turned on the two breakers to the oven, set the clock and checked operation and its functioning great now.

Have not run a self cleaning operation since the repair but that is the next step and now that those door vents are clear I suspect that the fuse wont trip again.

Lesson Learned: Check those vents for obstructions.

Similar oven selling at discount because its the end of the model year is now priced at over $1100. Fixed our unit for $50 and the added cost of a $20 furniture dolly that I already wanted to buy.

Give this repair a try its a piece of cake and well worth the effort.

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.

Removed the small metal panel covering the main power terminal in back of the electric range. Removed the nuts holding the red, white and black electrical wires from the range using the appropriate socket (there will be two nuts on each bolt end). Removed the two screws holding the main power terminal block with appropriate screw driver. Connect the new main power terminal block to the range using the two screws. Reconnect the red, black and white electrical wires coming from the range using one nut for each wire. IMPORTANT: do no over tighten the nuts because the bolts could snap. Reconnect the pigtail and secure the small metal panel covering the main power panel.

Opened overn door and inserted allen wrenchs through the holes in the door hinges. Close the door until it makes contact with the allen wrenchs, then grasp the oven door handle and the bottom of the oven door and lift up to remove the door. Place the door on a flat surface,(I used a bed) and remove the screws to gain access to the glass. Upon re-assesbly, leave door flat line up and re-install all screws before putting the front pannel back on. Insert door back into the oven and open, remove the allen wrenches and close the door. The process is easy and will take 30 minutes to an hour and save you a $100.00 service call!

Read the instructions in installation manual to remove door. Kept removing screws. Was surprised to find two panes of glass between the inner glass and the outer glass. Cleaned all the glass (4) and the inside of the door. Looks brand new. Be careful with the insulation; be sure it is pushed back or it will show from the outside.

I pinpointed the location of the sound, took off the protective plate, felt it vibrating against the plate. I disconnected the power supply, and looked at the wirings and how it was connected, saw some burning residue surrounding the area of the Transformer. Then figured that I could simply replace this. I wrote down the Model and Serial number of the Stove, searched online, found this site. Located the part on the diagram, then simply ordered it. My part arrived in 3 days, and had the part replaced the next day. Couldn't be a smoother fix. Thanks.

I bought an old house where this Double Wall oven was not working. I looked at the suppressor and one of the Red diodes was burnt. So, I removed it, took a picture of it and send it to the sales rep. She located the part exact part and sent it within 3 days. Then I installed it and the oven worked beautifully. My Appliance repair man gave me an estimate of $760.00 and I was able to repair within 30 minutes and $60.00 part. Really happy, Thank you .
