Re: Replaced the displace board and oven is now not...
I just had a repair company replace the display, control board and wiring harness on SCD272 double oven to correct a dim display (kit part # 492071). Instructions on kit say that all three pieces must be used together for proper operation.

I have a Jenn-Air double wall oven with a very dim display light. Replaced c3 capacitor 68uf 35w - with a 100uf 50w cost $1.60 closes size available at Radio Shack and works good as new. Requires soldering onto the circuit board. I price a replacement part for $276.00.
Hi, this will happen over a period of time and its just heat related. the control panel isn't insulated properly and , there has been a larger than normal transfer of heat to the inside of the control panel where the circuits are housed.
If this is a problem, i recommend replacing the control board. it will fix the dim issue.
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.)
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!
