    Our display has been on it's way out for a while. Works only with oven
    use (dimly). Recently the temperature control for the oven itself seems
    to not be working correctly. Wonder if the templ. problem would also be fixed by replacing the boards?

The circuit board is for the display/touch panel. It is mounted on the back of the display panel itself and connected to the other circuit boards by two multipin connectors. When you remove the display panel (3 screws on top, 4 on the bottom) you will be able to GENTLY detach those connectors. They are low voltage and may be handled safety even when the oven is powered, but I agree that turning off the oven circuit breaker is good practice.

To remove the circuit board, GENTLY release the two black plastic tabs; the solder pads are underneath. I too used a 100 mf capacitor because no local supplier had a 68 mf hi-temp. Observe polarity; the (-) lead goes towards the center of the board (away from the edge connector.)

BTW, I had exactly the same symptoms (display goes dim, then goes out altogether.)

If you haven't already, replace the capacitors on the clock module. I had the same problem with a similar oven. See this link for more info:

Oven digital lighted display is dim


You need to replace the C3 capacitor on the control board

http://fixitnow.com/wp/2009/01/28/cheap-fix-for-a-dim-display-on-an-oven-control-panel/

You can replace only the C3 - it is 68uF / 35V and you can go to Radio Shack and get their part # 272-1028 - 100uF/35V one. It takes all but 10 minutes to re-solder the new one in place

Display on my Jenn-Air electric wall oven is very dim


douglas9101,
I had the same problem and found the solution on-line.
Replace the C3 capacitor on the dispaly module. (100 UF, 35 volt, high temperature)
The local Jenn Air dealer wanted $211 for a new display module.
I purchased a Cap from a local electronics supply store for 79cents.
The only problem is that you need to have a soldering pencil/iron, a solder ******/wick and a small amount of solder.

Steps I had to take on my oven:
- Flip the AC breaker supplying the oven to off to be save
- remove 3 screws on top and 4 on the bottom of the display panel
- gently pull out the display panel and unplug the 2 cables to the display
- unclip the ribbon cable to the display module
- unclip the module itself by pushing on the 2 black tabs
- locate C3
- unsolder C3 and replace with new Cap- keeping the polarity strip the same as theh old Cap
- reasemble in reverse order.

It took me all of 20 minutes. It may sound difficult but is very easy if you have the tools
Good Luck
K

Dim display.


The display sits on a circuit board. Pull the board out and replace capacitor C3. It is 68 micro farads. I used a 47 from Radio Shack and it works great. If you can find a 68, that would be ok too, of course!

Display light


Found out that I could replace the C3 capacitor with a 100uF 35V (high temperature - 105 C). Spent $1.69 for the capacitor and 1/2 hour taking the unit out, soldering the new capacitor in, and remounting the upper clock unit back on the oven. Works like a charm. No need to buy the whole Clock/Temp unit, waste of money.

Dimming temperature and clock light on display window


I found capacitor c3 (68 uf 35 volt) had leaked and dried up, causing the display to fail. I unsoldered and tested c1, c4, c7, and made sure they were good, using a digital multimeter with the ability to test capacitors. C3 also had visible signs of leakage. Works like a charm again, and the display is bright like new!
