W30400PC Jenn-Air Wall Oven - Instructions

Turned off power to stove
Removed control knobs and retaining screws under the knobs.
Opened oven door.
REmoved screws (4) holding the face plate to the stove.
pulled the panel downwards.
Unscreewed clock circuit board.
Removed connectors (3) (See Below)
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.

Reverse steps

I have only two things to add to the other repair stories on this site: (1) Unlike the ribbon cables inside desktop computers, the ribbon cable on this range is entirely separate from the connector, which is permanently attached to the clock assembly. There are clips on the top of the connector at each end. Push them in and raise them gently to release the ribbon cable. (2) There are two Molex connectors attached to the clock assembly. The pins for one of them were bent on the new clock assembly I received. Before installing it, I spent some time gently coaxing those pins back into alignment. Use your fingernail, and be patient.

1) Unplug Appliance
2) Remove stove front (4 hex-head screws)
(Note: support front while removing screws)
3) disconnect (3) wiring harnesses
(Note: exercise care when revoving "data bus", release with small "dogs" on each side of plug.)
4) Remove Clock assembly (2 hex-head screws)
5) Replace Clock assembly (2 hex-head screws)
6) Reconnect (3) wiring harnesses (reseat bus plug dogs)
7) Reattach stove front (4 hex-head screws)

Note: Before the repair, all functions and displays worked just fine, they just weren't illuminated so you couldn't read any thing. It really steams me that I had to pay $141 to replace a 50 cent light.

First tried the Oven Temp. Sensor, no difference. Next replaced the Electronic Relay Control Board. Successful repair. Total cost: $290.00. I removed spade connectors and molex connectors one at a time, placing them on the new board.

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.

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

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!

1. Removed knobs and front panel. Disconnect wiring.
2. Order part and installed. Done

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.

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!

Turned power off to oven, removed control knobs, took out four screws under panel. Removed four 1/4" sheetmetal screws. Removed front cover, Removed two additioanl screws that held front cover to corner bracketts, Removed two screws that held clock to plate, removed each wiring harness and pluged into new part, unplugged wiring ribbon from old part plugged into new. reassembled. Turned power back on and tested and we had light!!!One repair company was going to charge us over $400 to make this repair!!!

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..

Open oven door
Remove two sets of four screws underneath the LED display
Remove stove handles (pull off easily - no tools needed)
Lower flat plate width of oven and about two inches deep should be able to drop out from under the clock display.
Remove face plate over clock.
Unscrew four screws holding clock unit down.
Undo two electric connectors and the thin ribbon connector - the thin ribbon connector is different - the ribbon comes loose and the black plastic connector stays in place on the board.
Press the thin ribbon connector ends inward and pull up to detan ribbon on old one and then to insert ribbon on new one.
Reverse the rest.
Not too bad!
