Main contactor code convotherm 20-20 gas oven code is I think e70 only some times seems to work ok when in diagnostic mode?could the door switch cause this problem?
What is the exact code and 20-20 model? There is no 70 that I can find. And the codes are different with different control systems. Also different accessories. E60’s, E70’s, and E80’s are VFD codes. Often just a ribbon cable connector problem with communication.
