I had a customer with a dim clock and dark oven temp on a built in Jenn Air (made by Maytag) oven.
They didn't want to spend $150 (or more depending on parts store) + my labor to fix it.
I did some research and found that the C3 capacitor on the clock/display board is the problem.
I went to Fry's Electronics and bought a replacement capacitor for about $2. All I had to do was un-solder the old one and put the new one in place.
You need to have soldering skills to do this.
Bottom line, I charged the customer my basic labor rate and $75 for rebuilding the board.
The saved quite a bit, and I made more than I would have replacing the board.
I imagine this would work on many models.
I plan on repairing many more boards in the future.
Any thoughts on repairing vs. replacing control boards in appliances?
