Notice warning on top of page one regarding working on the unit with the power connected.
Try turning the power to the unit off for 10 seconds, then turn it back on and tell me how that worked,
We can go from there without a time limit. Please do not forget to rate my work when we get it fixed.
Thanks, ***** ***** like the printed circuit board may have been damaged by the power spike that hit it during the power outage, or by working on the unit without turning power off to it,
If you can send me two photo's one of the printed circuit card so that I can see the entire card clearly, and one of the wiring diagram glued to the inside of the units electrical control panel, close up, well focused and from straight on.... I can mark them up with further trouble shooting instructions,
We can go from there.
Hello again, coaching you trouble shooting that inaccessible mess of wire connections could take days, and still not end well.
I am going to leave you with the statement that replacing the printed circuit board has a 70 to 80% chance of working, the rest is too compact and the diagram the manufacture provided on the printed circuit board is too vague to allow reasonable trouble shooting of anything else.
I will opt out, we can see if anyone else here has a better idea for you.
