W30400PC Jenn-Air Wall Oven - Instructions

Once the display became too dim to read, I removed the front panel to determine how to access the piece and to check part numbers so that I could order the proper piece. Once the part arrived, being familiar with the disassembly, it was simple enough to replace the part quickly. The part came out with two screws and the connections were standard electronic multi plug, making the replacement simple. When we turned the power to the unit on, it worked first time.

I removed the three screws that was on top of the display enclosure. I then removed the four screws on the bottom of the display enclosure.

I unplugged the two connectors going to the old enclosure and removed the enclosure to the kitchen table. I then pressed the two locks on the ribbon cable lock and pulled up on the ribbon cable lock. I was unsure how to do this, but if you press the two tabs and slightly pull up on the lock, the ribbon cable will come free.

I then removed the four screws holding on the old display and put the new part in. Fastened with the four screws and connected the ribbon cable, squeezing tabs and raising the black lock, inserting ribbon cable and pressing down to lock in place.

I then took the enclosure to the oven, connected the other two sets of wires and mounted the enclosure with the three upper scres and four bottom screws. Took me about 15 minutes. My $148 PartsSelect part was $267 locally.

I looked at the schematic from PartsSelect, undid the 8 screws and replaced the clock assembly. I probably saved $200 on labor doing it myself. I had the clock repaired in 30 minutes.

I first turned off the circuit breaker for the range. I then I removed the four hex screws from the underside of the panel and then dropped the panel to expose the clock assembly. I then removed the two screws holding it in place, disconnected the cables and removed the old unit. I then reversed the procedure to install the new unit. I next turned on the circuit breaker restoring power to the range. And like magic I once again had light. I know I must have made by Daddy proud. I should have done it sooner. Thank you for making it so easy by sharing the "how to's" with me. It was especially helpful to have the model number.

Turn off power to the stove. Pop off the burner knobs and remove the screws attaching the controls to the front panel. Open the oven door and remove the four screws attaching the panel to the oven frame. The panel slides down giving easy access to the circuit board. Remove the two connectors and the ribbon cable attached to the board. There are small clips on the side of the ribbon cable connector that release the ribbon cable. Unscrew the board and install new board. Reattach the cables, put the panel back in place and attach. Reattach the burner controls to the panel, pop the knobs back on, power the stove back on, put on a pair of sunglasses to view the now blazingly bright display and admire your work.

NOTE the flat ribbon needs to be removed by pinching the ends of the black connector , liftiing and GENTLY pulling the ribbon out of the connector. The black connector remains on the circuit board.
When in stalling the ribbon, pinch the ends of the black connector and lift slightly, insert ribbon, then push down on the loose side of the connector until it snaps shut ,forming a tight connection.

Remove four screws behind control knobs. Remove four hex nuts under control panel (open oven door to locate). Pull control panel down and out. Remove two hex nuts holding clock assembly. Remove three wire connectors on the old clock assembly and carefully insert on new clock assembly. Reverse instructions to re-assemble. It's a breeze to do! Took longer to get my tool box than the time it took to replace the clock assembly.

First I took the screws off of the top hood which can be found right underneatch, this allowed me to access the panel bolts and unscreww them. We then got it far enough so that we could easily replace the old with the new and plug things back in and we were good to go. I am not sure but we must have save hundreds of dollars in a repairman.. This website is awesome..

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.

My wife help take the door off. It was a little heavy . The door came apart very easy and went back the same way.We save over $300 by doing it our selfs.

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.

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
