Question about Jenn-Air WW30430P Stainless Steel Electric Double Oven
I have the Jenn-Air wall oven model WW30430P and the LED display is fading, I can still see the clock but can no longer read the temperature nor the timer. If anyone can diagnose the problem and especially the part numbers I would need to replace I would be grateful.
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.

Made the change using 2 capacitors but there is no change. Any other suggestions?

We have this happen once after 4 years. Just like others, we replaced the display board, it seems to work fine. It might have something to do with the oven doors are not closing correctly. Please refer to the same model with topic, "The oven doors are not closing all the way".

We've had this happen twice. Make sure you don't spray the screen with any cleaner...liquid is what causes this. Had to replace the board...$390. Sorry.

GREGGLEE HIT THE SOLUTION ON THE NOSE. I USED THE 100 MICROFARAD AND HAD THE JOB DONE IN LESS THAN 30 MINUTES. MAKE SURE THAT YOU ALIGN YOUR NEGATIVE LEAD FROM THE CAPACITOR TO THE NEGATIVE HOLE IN THE BOARD OF THE C3 CAPACITOR LOCATION (IT'S MARKED BY A SOLID BAR NEXT TO IT). GOOD LUCK - IT'S NICE TO SEE THE TIME AND SETTINGS AGAIN.

Tnx for the inputs. I found the perfect solution -- I ripped out the ovens and sent them where they belong, the dump. Replaced with a different brand. Will never buy Jenn-Air or related brands (Maytag) again, nor will I do biz with the dealer who took my money without fixing the problem.
