W30400P Jenn-Air Wall Oven - Instructions

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..

I first turned the power off to the stove at the junction box. Removed the control panel that contained the clock assembly by removing 4 phillips head screws. While my wife held the control panel, I disconnected the two pin connectors and one ribbon connector attached to the clock. I then removed the two phillips screws holding the clock assembly in place. To disconnect the ribbon connector, press the release buttons on the side in and the center loosens and pulls out, releasing the ribbon. There are two plastic tabs that fit into two guide holes on the ribbon. The best part of this is that 6 months ago, two number keys and the timer button had quit functioning and I thought I was going to have to replace the touch panel also. Apparently it was a problem with the circuit board on the clock assembly because everything works now! My ife is very happy!

Got a bent metal coathook to temporarily release the oven door, removed the screws from the old probe, inserted the new one, and hooked it up, using the one of the plug adapters provided. Problem solved! The oven door latch was now disengaged, the oven would now accept temperature inputs, and the rear cooling fan (which wouldn't shut off) now turned off. That's a lot of things working better for less than $50!

Removed screws on face plate, disconnected wires, placed on counter, removed hex head screws. Removed one end of electric type circutry, replaced with new part and reassembled.

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

I first turned the breaker off. Then removed the screws under the display with the oven door open. Then removed the side screws. Then removed the trim kit for the microwave which exposed 3 more screws. The middle one with the Micro Door open. The complete display panel then was removable. I took a digital picture of the 2 wire and 1 ribbon connectiors (I know-anal). Then removed the 2 wire groups-struggled somewhat with the ribbon connector until I realized by trial & Error that the 2 little tabs on the sides only pull upward, releasing the ribbon. Removed 4 nutdriver screws to remove old display-installed new one in reverse fashion. Then I CLEANED everything I could reach it was so dirty! (I live in the desert,duh!) I just paid great attention to how it came apart and it was relatively easy. The best part is that I didn't have to remove the Oven/Microwave unit to do the repair.The new part works perfectly, thanks!

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.

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

Had to remove oven from mounting cabinet to get to the back since the wire lenght to the conector was to short to come through the mounting hole.
Other than that the repair was straight forward. 4 screws to dismount the Oven from cabinet, 2 screws to remove Sensor and 3 srews to open the back of the oven once out in the open. New cable adapter that came with the new sensor was needed in my case.

My husband ( a superior handy man) very easily replaced the glass on the inside of the oven door and further replaced the hinges which had sprung yrs ago when I rested a 30+ lb turkey on the door. He removed the oven door and it was obvious to him how to repair the problem. The oven is back to heating correctly.

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.

Initially I made a false start by pulling out the stove, which was not necessary. Then dropped control panel by removing the several screws on the bottom of control panel. Removed the three connecting cables by freeing locking mechanisms. (The locks on the ribbon assembly are on both ends of the connector plug). Removal of circuit board then obvious. Installation of new circuit board quick and easy. All displays then worked OK. I added a fiberglass heat shield around the circuit board and time will tell if this worked or was a mistake;
Your troublshooting tips were very helpful.

I am curious how the chap who found capacitor C3 to be defective zeroed in on it without a test harness.

The part came right away!
Removed six screws from above door, than pull knobs off and remove four screws that were under knobs.
Front panel pulls off. Remove display and put back together.
Peice of cake.
Wish all my projects were that easy!

cut off power to stove & made sure it was OFF.
removed the few screws on the underside of front cover.
lift cover and un-screw the clock/display
I then removed the wire strip feeds (one has friction tabs that need to be lifted before you pull it.. it's the flat ribbon cable use the butter knife to lift the tabs...easy does it)
put the new clock in and reconect the wires. push the ribbon in and push the tabs.
All done and saved $160.00 bucks

Removed the oven from the wall. Removed back cover and unplugged sensor from the harness. Remove and replace sensor from inside the oven. Reconnect harness and reinstall back cover. Secure oven back into the wall.
