WM277B Jenn-Air Microwave Oven Combo - Instructions

I removed the bad element - two screws, and tested it on my meter as recommended. The test meter showed it was bad, so I ordered a replacement element from PartSelect. I did check getting a part from a local dealer, and it would have been $10 more. The help and recommendations I recieved on the PartSelect repair forum make it easy.

Removed the two screws holding the sensor to the rear oven wall. pulled out sensor wire. It was caught on other wires behind the oven. removed the three screws holding the 8" inspection plate in the center of the rear panel. Carefully move the insulation and reach in to grasp the back end of the sensor wire. Once free from the snag it easily pulls out with the sensor just as stated in the video. using the appropriate adaptor it was easy to re-asseble and and attach to the oven wall. Replace the rear panel with the three screws and it was done

My wife removed old element and replaced new element by removing and rescrewing 2 screws and detaching and retaching 2 wires to thr respective elements in about 5-10 minutes.

The sensor is mounted in the top right side of the oven.An extra long screw driver helps to avoid damage to the sensor when replacing it.The connectors were the opposite to the old sensor and I did not see that there were adapter cables included. It might help to connect or tie these together as I only expected the sensor and did not look for adapters.I had cut the wires and used wire nuts when I found the adapters.The repairs works fine.

Spoke to your very helpful staff, who advised me that a likely problem was the oven sensor. I took a chance and ordered the part, which came promptly. Your service video for the part was most helpful in my decision to try the part. Installation was a breeze, but it was the oven controller board that had failed and not the oven sensor. That called for a service professional, who ultimately fixed the problem. Your service though, was excellent and I would highly recommend you to others.

First cheapest try, removed top cover,three screws on each side .replaced thermo snap overheat switch,not the problem. Then I ordered a timer controller removed three screws above and inside the front panel and it drops forward to access the controller. Removed 4 screws and four pulloff connectors and replaced the controller.Cured problem.Diagnosis was the hardest part of the repair.

Took screws out of the back on the side the sensor was on, unplugged it & took out the two screws on the inside of the oven to release the sensor. Put new sensor in place with the two screws & used one of the adapters to plug in the new sensor. Put screws back in the back panel & turned on the oven which unfortunately is still 50 degrees low. Need a new clock with computer which is out of stock & unavailable. I was an electrician for 25 years so didn't experience any problems. It was a cheap thing to try.

I removed one screw easily. The other screw was difficult to remove without stripping it. I sprayed wd 40 and let it sit overnight. The next day, my husband sprayed it again and after trying several different size phillips screwdrivers, he got the second screw out. He easily removed the element and then the two wires from it. He attached the two wires and replaced the screws. We tested it and it worked. The best part is: my husband scrubbed the oven before putting all the parts back!

Turned off breakers to oven. Removed two screws that held oven in cabinet. Removed oven door by opening slightly and pulling up on door. Pulled oven out 1/3 of way. Took out four screws on top of control panel. Took oven light switch off by unscrewing holding ring. Removed temp knob on right by pulling. Removed start / stop knob same way.Removed glass straight out. Removed four screws that held elecrtonic clock conrtol board. Unpluged three wire plug from right side and the nine wire plug from the left side. Worked board out at and angle. Went backwards to connect and replace board, screws and door.Slid oven back in and tested oven after turning breakers back on, worked like new.

I opened the oven door and unscrewed the two screws that connected the element to the back of the oven. I then pulled the element forward but it would not expose the electrical connections that powered it. I pulled a little harder and it would not pull through the insulation. I then decided that it must be accessable from the back. I took off the door the lighten the oven. I pulled the oven out of the cabinet till the conduit was taught and I could just barely see that there wasn't a panel to access the connection. I then put the back into the cabinet and pulled a little harder yet on the element and the connecters pull through the insulation. I was then able to test the element with the multimeter and decide the power was getting to the element but no heat. I ordered the part the next day. Recieved it the day after that, smokin' fast service I must add. Installed the element and it works like a new one. My wife loved it and then she loved me.

I installed the new oven sensor but the problem continued. So I ordered a new relay board and installed it. Still no luck. So I pulled the new board back out and started trouble shooting it using my electronic background. I discovered the new board was using a pin for L2 that had no exit on the backplane, so I removed it and installed it where I believed it should go. Reinstalled the power relay board and presto. My oven is working lie a champ. Louis

I removed the two mounting screws and pulled the harness through the opening unsnapped the sensor from the harness and installed the new sensor i didn't have to used the adapters the new sensor fitted
