WW2780B-C Jenn-Air Wall Oven - Instructions

Replaced the thermostat according to existing videos and had to adjust the thermostat using instuctions in the user manual for model CWE4800ACB.

Extremely simple repair to make. Move stove away from wall and disconnect power. Remove the oven racks. Remove the rear sheet metal panel covering the wiring harnesses. Caution: Sharp edges and corners on sheet metal.Sensor is located in upper left corner on rear oven wall. Using a long-shafted #2 Philips screwdriver, remove the two Philips head screws and gently pull the sensor 1" away from the oven wall. At this point, it will help to have an assist from someone while you are behind the range. Have the assistant gently tug on the sensor while you watch for wires moving on the rear of the range. After locating the sensor wires, gently disconnect the plastic connector clip. Note: plastic connectors become brittle with age and exposure to heat Move to front of range and gently remove sensor from rear wall by pulling the wiring through the oven wall. Before inserting the new sensor wire through the oven wall, "dry fit" the wiring connectors to see that the new sensor is a correct connection. Make connection, and secure the sensor to the rear oven wall with the two screws. Install racks, reinstall rear sheet metal panel, and connect the power. Set the oven baking temperature to a moderately low temp, 300 - 350 deg. to test the new sensor.

Part was perfect fit. Good product, good value, great service.

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

I switched the oven sensor easily enough, but it did not remedy the problem, so we are in the process of replacing the oven since it's about 20 yrs. old.

Unplugged the range, removed screws holding the old sensor. When I pulled it out, the wire connecting to the sensor was completely broken through,therefore I could not just pull the wire to get to the connector. Unscrewed one side of back panel to access the connector. Pushed the connector and wire of the new sensor through the hole ( and behind the insulation), disconnected the old sensor and connected the new one. Re screwed the new connector in place plus rescrewed the back panel. Plugged the range in and - Viola! Everything now works like a charm and I have my oven back. Easy-Peasy. Oh - I am an older female with very limited DYI experience. I just saved myself $650.00!

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

Oven sensor replacement was easy. Thermistor was installed in less than 15 minutes. After installation STILL had "F3" error message. Harness was ok, "Clock" or ECU needed to be replaced. "Computer" is obsolete, no spares available, some companies will rebuilt for $400+. Since the stove was going to the landfill I had nothing to lose by taking the "Clock" apart. It has one chip that is probably the power supply and control chip, another chip is an EEPROM with 128 bytes of storage and the last is a darlington chip that controls the relays. Cleaned up everything that looked like it needed cleaning with alcohol. When I reassembled the unit the pins for the thermistor harness felt loose, so I took it apart, again, and found cold solder joints on all four pins. It must have been there all along but plugging and unplugging the harness finally broke out the solder so I could see it. Soldered the pins back in and now it all works. It's worth a try if you're getting the "F3" message. If the relays on your stove aren't working it would be a good idea to replace the darlington chip. Good luck.

Removing the oven door and several layers of metal to get to the seal, is a fairly easy process. Our door had three different fasteners, torx head screws to remove the door, a very small flat head screwdriver to remove the chrome door trim screws, and a nut driver to remove the inner panels and glass. The replacement seal is over-large and must be trimmed. Care should be taken when fitting the integrated wire. Bending at the corners only, makes assembly much easier. Reassembly is the reverse of diassembly. Care must be taken that the seal wire hasn't popped out of it's seat when the cover is installed. This is the most time-consuming and frustrating part of the repair. Patience is paramount to get a good fit. Because I had made an odd bend in it, about one inch of wire was not properly seated after the cover was seated and tightened down. I was able to gently squeeze it into the seat with a flat tip screwdriver without removing any screws. The final problem area is reinstalling the door. Although two people would be helpful to accomplish this Task, I was able to accomplish it with the aid of a three foot piece of 2x4. By wedging the piece of lumber behind both hinges, they were held open under tension to allow slipping the door on. Once partially installed, the 2x4 can be removed and the door seated. Hope this helps.

I raised the top of my Whirlpool Continuous Cleaning Canning Oven, then had to unscrew 3 screws and a lock nut, then raise top about 4 inches, so I could put my hand inside to unplug the wires to the switch, and push it through the hole in front, of oven. Then put the new switch through hole and plug in new switch. Then screw down top; and close lid. Part #866294

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

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.

Flipped off breaker and removed oven door and pulled built in stove out so the back panel could be removed. Unplugged the sensor then removed the two screws securing the old sensor inside the oven and installed new sensor. Put stove back together and installed back into counter top, re-installed oven door, flipped on the breaker and oven works like new.

Replaced the long Oven Sensor but have not resolved the root problem. Oven still will not reach required temperature. Bottom element becomes red hot, but turns off and will not start again.

Removed the original element with a screwdriver and disconnected the 2 wires, it took about 2 minutes. Got online with PartSelect and easily matched a replacement part. Ordered the part and received it within a couple of days. Very impressed with the ease and quickness of the order processing and shipping. Took the new element and connected the wires, screwed the 2 screws back in, it took about 2 minutes. Turned on the oven to check and everything worked perfectly. Very happy with the overall experience with PartSelect. Thanks!
