All functions work when in self test mode except fan and lamp. Is this a regulator issue? Thoughts? Lamp and fan not getting 24 volts.. have more than one power supply.. but this isn't the issue.
I swapped out ic 42 just now.. didn't help. I noticed it controls fan and lamp. Next.. IC 9 and 33 seem to be in the path to control things... Is there a way to test those before swapping-out chips since they're a little harder to replace? Is 9 or 33 more likely to be out? which is more common to fail?
