Thermador oven problems

Anyone?!?!?!
I have a Thermador and here are the problems. Oven, griddle and broiler dont always light. Oven lights stay on when oven on and off when oven off. Cant turn off and on with switch. Oven indicator light does NOT light, but heating and clean indicator lights do work. (Fault indicator uses oven and heating indicator lights, so all I get in my fault is the second half, the heating indicator light.) My fault is three blinks. I have replaced the PC board with no change. Any ideas???
THANKS!

Hi.

You need to do several things.

First - the oven thermostat/potentiometer and the selector switch should be replaced.
Then you need to check the air switch and cooling fan performance.
Then - test the door switch and the light switch (continuity test).

With all those things done you should be able to illuminate the problem.

Thank you. Post the results.

PS. You can return all unused parts even if they been installed.

Well, it took me a while to order parts (bad economy and all). I replaced the selector switch and oven potentiator and all seems to be good for the oven (although my default indicator still blinks) But now my griddle is not working. ??? Igniter works, seems like no gas coming thru line.

Hi.

Check the gas solenoid 418064 for continuity. If it’s open - replace it.
