I have a Thermador SC301 wall oven and the display has faded out. Thermador says I need to replace the whole control unit ($500 for the part!) Any cheaper fix?

I have just repaired two SC301 ovens myself, but it is alot of work. You can get the oven's LED lights reconditioned at a company called CGI industries. Look them up on the web and click on the link for thermador. Removing the led panel and oven relay board is an involved job, but easier if you do it the correct way. First, turn off the power to the oven. Then pull the oven out of the wall socket about 1 quarter of the way. Remove the top cover of the oven with a phillips screw driver. This reveals the oven relay board. Take a digital picture of the board to remember the wire positions, or alternatively write them down. You also need to remove the touch panel (two screws underneath) and gain access to the LED. Remove the LED panel and wires. ship both to CGI (boards only) and you will have them back in less than a week. Costs about $170 before shipping. Reinstall and turn power on. All is good.
