WM2780B Jenn-Air Microwave Oven Combo - Instructions

I was told by appliance repairman that sensor and electronic panel were out - so ordered both as PartSelect was less expensive (about 1/2) than service call price. Sensor was in stock and arrived in 2 days, panel was special order from factory.
Replaced the sensor. Pressed Control Lock pad for several seconds and oven clock came on. Was able to set baking temp, broiler, and convection operation as normal.
Canceled order on panel as Sensor fixed my problem.

take door off. remove screws holding door together, take door apart. remove worn seal. install new seal. reposition insulation and door window at the appropriate location. begin re-assembling door in reverse order making sure that apprpriate pressure is applied to keep the seal in place. re-attach door to hinges. project worked out well. new seal looks great. would have been a costly repair if I called a professional. I'm handy, but things like this are often hard the first time. you have to take your time and be cognizant of putting it back together the way you took it apart.

Unscrewed the cover of the microwave replaced the blown fuse with the new fuse, plugged in the microwave and tested all functions and everything worked fine. Thx for quick delivery.

We made the mistake of taking the door apart before we received the replacement parts. After waiting several days, which was fine, the parts arrived. Then we had to figure out how it went back together. My wife and I did it and enjoyed working on it. However....after getting it partly reassembled, we (I) found four extra screws. We took it apart again and then put it back together. Turning the door over we found that the glass assembly had slipped. This meant that we had to take it apart again. This went on two more times LOL. Then the gasket gave us a couple of small fits as well. All in all it was a neat experience. I do suggest, unless you are experienced in appliance repair, to NOT disassemble the door until the parts arrive.

The comments from others on the website were a great help.

Thank you.

SHUT OFF BREAKER FOR OVEN! pulled oven out to get at backside,removed 3 screws on back coverplate,removed 2 screws inside oven at sensor in top left corner of oven,disconnected plastic clip at back ,pulled old sensor through hole.replaced sensor with new in reverse order. 15minutes tops.

Easy as pie to do this repair. You first remove the 2 screws holding the element in. Then you carefully pull out the element and remove the wire clips at the ends. Just reverse the process with the new part.

By the way, I ordered my part from parts select on a Friday afternoon and it was on my doorstep Saturday morning..... and this was with regular delivery!
I would buy again in a heartbeat from parts select.

As the probe is a plug-in item that would normally be out of the oven, there was nothing more to the repair than checking that the new probe plug fitted the socket and that it was detected by the oven. Then the old probe was consigned to the trash.

Everything checked out, and the probe was used satisfactorily within a couple of days.

Followed the instructions given by Paul from Mickleton, NJ. Very simple, no problem. Using two small blocks of wood to hold spring loaded hinges out while I replaced the door on the hinges was a big help. Thanks for the excellent delivery time. Great service.

My oven didn't work anymore and it was beeping terribly, with a FO code on it, which meant "Control Panel problem" the only way I could stop the beeping, and still use my microwave on the top, but on same braker switch, was to disconnect a ribbon like wire.. After ordering a new control pad, I called a repair person and asked him, "how do I know for sure if it is the control pad, and not the touch panel which the pad is attached to.? He said the test that he would have done was to disconnect the ribbon like wire and if it stopped beeping, it was the touch pad. Not the control panel... That little sentence saved me $250, so I just returned the panel and ordered the touch pad......it was a easy great fix .!!! I'm so proud of myself for trying and saving money too !

Serviceman took out broken glass by removing door and separating front of door from back of door. He carefully removed all broken glass Then replaced with new glass and fastened door together . He did repair in 20 minutes. Oven is like new. Thank you very much for still stocking this part that allows me to keep my oven repaired.

Opened the oven door and locked the spring hinges in the opened position with two 10p nails. Removed the oven door. I dismantled the component parts of the door. I then removed and replaced the broken glass unit,reassembled the door, slid the door onto the hinges, tightened two screws to lock the door in place, removed the 10p nails, closed the door----- and that was it. Less than one hour. The job was accomplished using only a Phillips screwdriver.

Using exploded view and previous customers' comments, I disassembled the door. It was primarily a matter of finding all the screws. I recommend taking the door off first (I didn't), but watch your fingers. The hinges have very, very strong springs and you can hurt your or your helper's fingers if you're not prepared. The hardest part was keeping all the insulation in place while your're installing the assembly. I also replaced the gasket. That takes four hands, two to hold the gasket in place and two to reinstall the window assembly. To put the door back on the hinges, I pulled them out from the door at a 45-degree angle (takes some effort), put screwdrivers through holes in the hinges, and guided (with help) the door back on.

I didn't. Don't know how to get to light bulb to change it for this specific model

I slide the range out and unplugged it from the outlet. I removed the back of the oven ( 8 screws ) using a cordless drill and phillips bit then with a phillips screwdriver I removed the oven sensor (2 screws) then I installed the new sensor , reinstalled the oven back , plugged the range in , slide it back into place and that was it. This repair took about 10 mins and the oven works perfectly. Thanks !

unscrew microwave's cover,test the fuse which is located at top rear left side, the fuse is inside a plastic tube,if the fuse is burnout,just replace it.
