W30400BC Jenn-Air Wall Oven - Instructions

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

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)
8) Plug appliance in to power outlet

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.

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.

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

Turn off breaker to stove. Open oven door and remove screws up under display. Slide display down and tip top edge forward so you can see the back side. Remove 2 screws holding digital display and disconnect 3 wiring plugs. One of them is a ribon connector and you must squeeze it to make the front edge rise up to disconnet the ribbon and again when putting new part in. Reverse the proceedure. It took my husband 10 min to replace the part. Being able to read how others had done it was invaluable.

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.

unscrewed the top face plate assembly disconnect 2 wire harnesses 4 screws to release display clock 1 wire harness and then reverse order

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.

installed part,turned unit on-temp still cold. reset digital control, up 35 degrees, still cold. un-plugged unit,re-connect after 10 min. still cold.

After trying to set the bake temp after the self cleaning, it would not heat up. I Googled the model number,selected your link because it mentioned my symptom,and said usually it is the temp sensor in the oven that gets damaged by the high self cleaning heat. Your site had a place to enter my model number. You provided a great exploded view of the parts, showing me my sensor,then you provided the part number of the kit i needed,and filled out the order form with payment method. Less than a week later I got my part with instructions. Your video showed me the two screws I remove from the front ,and I pulled the old part out and uplugged it's connector. Replacement was easy, and oven was fixed! Thank you for a great site! You held my hand through it all!

ordered new broiler pan

I shut down power at the circuit breaker, removed the stove knobs, unscrewed the underneath screws of the front panel, pulled off the panel, and the electronic board/panel was there.

I unhooked the wires (3 sets), and used the socket to remove the electronic board from the front panel. I put it all back together. Very easy-- less than 15 minutes!

First, DISCONNECT POWER or you can turn your panel into an arc welder. After that removed four screws that hold front panel in place and 2 screws that hold the display in place. disconnect ribbon cable and two other cables. Reverse operation for assembly.

For the self cleaning problem, replace door lock switch by pulling forward, use needle nose to remove & replace connector. Push into place. Very easy. Total 10 minutes for both jobs

Removed 8 screws and replaced the part (also did a good cleaning while we were in there)! Easy breezy!!!

Popped it in and now we have a well lighted control panel AND a night light for the kitchen. Just wish Jen air would design a longer lasting part!!!
