WM2780B Jenn-Air Microwave Oven Combo - Instructions

Followed instructions. Two screws frozen. Unable to loosen. Forced to grind heads off and replace with new screws.

I ordered the temperature sensor after watching the video and seeing how easily it could be changed out. Unfortunately, they don't tell you that it may be necessary to access the part from the back. When I tried removing the sensor from inside the oven the connection separated before getting to the hole. I tried for 4 days to try to fish out the other end. Finally, I had my brother help me remove the oven from the wall and take the back off at which time we were able to connect the new sensory. It turns out that the wiring is on the upper right hand corner of the oven and the sensor is on the upper left hand corner and the wiring is rather short. I am a 64 year old female and do the majority of repairs around the house myself, but due to the weight of removing the oven I enlisted the help of my brother. After removing from the wall the rest was a breeze. Just wish the videos or written info on the website was a little more clear as to the different ways of accessing the damaged part.

I watched the video, which was very helpful...the temperature sensor was hard to pull through the small opening in the upper back left oven corner. On the back wall of the oven was a large removable circle, so I unscrewed that piece and was able to gain access to the wires attached to the temperature sensor and push it through the small opening. I used one of the new connectors, pushed it back through the small opening, screwed it back onto the oven wall, replaced the circle opening and tried the oven again...unfortunately, there was no improvement in oven temperature! My JennAir wall oven is about 17 years old, and I thought I would try this $30 repair prior to purchasing a new wall oven, but it looks like I will have to do some overtime and buy a new oven. Any other suggestions would be welcome.

The thermocouple was suspect. It should be super easy- two screws, but the wiring harness would not pull through on my oven. I confirmed the procedure with the PartSelect video which is good. The harness was caught and broke so I had to pull the oven out partially to get to the harness. The sensor did check bad on the multimeter (resistance too high- Google it, I did) so I ordered the part. Once the new part was installed the oven still did not function. So I had to get busy with the multimeter and pull the oven again. On the back of my oven near the wire to the bake element is a Hi Limit Switch which cuts off the bake element if the outside of the oven gets above the preset temperature. Mine was cracked and faulty and had to be replaced. The oven works great now.

Followed provided video

We removed the 2 screws at back of oven that hold element on, which took some doing as they were very rusted. We then pulled old element out; this proved a bit difficult because the ends of the old element were stuck in the insulation behind. We had to wiggle the old element back and forth a bit to get it loose from the insulation. Other than that, it was easy.

Took the oven door off hinge. Took door apart pulled off old seal from inside of the inside panel of door. Replaced with new seal.

Decided since the glass was broken I might as well replace the door seal. Getting the door off and on was the most difficult part of the process as the door hinge springs are quite strong. Remove screws on the hinge. Slide door off hinges. The hinges will close rather hard. Remove screws along the outside, then inside. Keep all the screws in some order as they are different sizes. More time to clean the door than actually installing the glass and seal. Re assemble. Trick to getting the door back on is to open the hinge spring to the broil position and place a thin screwdriver in an opening in each to keep in an open position. Slide door down to the srewdriver stop and then fully open. You can then slide the door fully onto the hinge, replace the hinge screws. Easy ,for a simple housewife.

Removed back of stove - 4 screws on top, 3 underneath. Unplugged wires from element. Removed element - 2 screws in front and 2 in the back. Installed new element, plugged wires back in, reinstalled back panel.

I removed the old thermostat and replaced it with the new one using the supplied wiring adapter for my model of range. Parts Select made this an easy project. Thanksyou

Removed the screws from the back of the oven to remove the damaged element; removed the electrical connectors and reattached to the new element and screwed it back in

opened the door; put 12 penny nails in each hinge through the holes for it, removed screws above hinges; slid door off; laid it on a towel on the workbench; removed side/top/bottom screws and laid the outer door aside. removed the screws from the inside of the door, laid the inside glass aside, removed the glass assembly (broken), cleaned the loose glass out, laid the new glass assembly in place, replaced the panels and screws and slid the door on the hinges, removed the nails and closed the door. 35 minutes. Never did it before4. Part fit great! Thanks to partselect for having the discontinued part!

Remove 2 screws in upper left corner of stove holding sensor in place. Pull sensor out and disconnect plastic electrical connector. Select appropriate adapter (both styles provided with new part) & reinstall. Power up stove and select bake on control unit to test. Works like a charm!

removed front of range door. removed old seal and replaced with new seal. clean and reassemble range door. repair very simple and fast.

Remove the door. Place small screwdriver in each door arm to prevent extraction. Remove approx 20 screws. Remove the seal. Replace the new seal. you will need help in holding the seal in place until you car install at least two screws. Very straight forward. Took 20 minutes. Even a cave man can do it.
