The clock/oven control module died by showing fault F3 (oven temp sensor) but checking out the sensor showed it was fine. The module has also been degrading over the last 1-2 years with the display fading in and out, initially after the oven had been on for a while, then occasionally with any key actions. (I figured the caps had dried out and replacing them was on the to-do list)

I replaced the module, now oven works and no fault codes, but the display fades out after the oven is in use for a few minutes. When the display blanks, pressing any key will *usually* cause the display to illuminate. Other times it just comes back to normal brightness on its own.

I am thinking the supply voltage is being affected by the board with the transformer on it, but I'd like to know what the signals coming into to control module are, i.e. pin numbers, name, and possibly a value such at 24 VAC.
I'd like to be more systematic in my troubleshooting of the problem instead of throwing parts at it....any help is greatly appreciated.
Thanks
