BrianGem posted a great solution back in May of '08, I just completed that fix on my own Jenn air, took me about 30 minutes once I got the correct capacitor.

Fix: Replace heat damaged capacitor labeled C3 on display board, Hard part will be obtaining the 35Volt 68uF capacitor, I'm lucky enough to have a Brother in the electronics design field who found me a couple of high reliability caps designed for hot applications, He does not recommend changing sizes without design review for fear of overloading another component, however several other posts have indicated that a 35V 100mF cap has worked fine for them.

TURN OFF POWER TO OVEN PRIOR TO STARTING ANY REPAIRS.
My control panel was attached to the oven with 4 screws accessed from above the top oven door, the panel slid up about 1/2 " and lifted off, Unplug the ribbon cables and the panel can be removed to a convenient work surface. The display board itself is mounted with 4 screws and connected with a wide flat ribbon cable, the suspect capacitor is surface mounted to the reverse side of the board, two plastic clips need to be released (gently) and the ribbon cable unplugged. Capacitor is likely discolored or leaking, Using as small a soldering iron as you can find De-solder it and replace with new, match polarity marks and don’t use any more solder than needed.

I wish I had done it myself like solution #1. I had a repair man come and replace my board when my temp went dim, and now I can't get the oven to self clean without a fault lite going on.

I'm not very impressed with this oven.

Door will not close all the way...


This is likely one of two problems. Either the fiber gasket is getting in the way or if it is like ours one of the hinges is broken or bent. The Hinges can be replaced for about $13 a piece and is not a difficut job. On our the oven was also opening more then 90 degrees and wouldn't close more then to about 1.5 inches away from full closure.

Am negotiating a home inspection on a house with WW30430P Jenn Air Wall Ovens; neither of the doors close. Is there a solution?


There are several models of Jenn-Air ovens that had issues with the door closing. The only solution is to replace the door hinges (unless the doors themselves are bad, you can see this if you open the door, the porcelain on the door will be bulged and cracked right where the hinge joins the door). If the doors are bad, the hinges and the interior door panels need to be replaced. Hope this helps!

LED Display fading


As noted in solutions to other Jenn Air ovens, this is often solved by replacing the capacitor labeled C3 on the circuit board that contains the display. Oven heat apparently causes it to fail over time. This is a solder connection to the circuit board. Not hard if you have any experience with this kind of soldering it is straightforward.

Seven phillips sheet metal screws to remove panel assembly, plus two electrical connectors. One ribbon connector from touch panel to board, then four 1/4 hex sheetmetal screws to remove circuit board from touch panel and metal frame. Then soldering iron.

It did work on a 40300 dual unit, which is same as this model except for cosmetics.

Capacitor is 35 volt 68 microfarad. Radio shack has 100 microfarad, which one report says works. Radio shack doesn't have a 68, but they do have 22 and 47 which mounted in parallel give 69, which is within tolerance. That's what I used. The capacitors cost $1.29, less than 1% of the cost of a new circuit board.

The electrical panel does not light up


I'm afraid you are going to need a new display board. Not very hard to change but a pricey item. Have seen this problem a few times. Good Luck!
