Hello, I can probably help in one way or the other, but it will probably not be a fast or easy solution, you may have to execute some repairs and order parts... or the problem may be so complex in relation to your skill sets that you will have to call in a local technician with instruments.
Please attach a well focused, close up photo of the wiring diagram glued inside the service panel, the picture needs to be close up, taken from straight on, perfectly focused and in very good light.
You can use the paper clip- icon at the right end of thetool bar at the top of this dialog box to attach it here. ,Include a picture of the thermostat wire connections to the printed circuit board in the same area.
If there is no paper clip-icon, look for the '+attach files' link at left of your send button.
I can mark it up with trouble shooting instructions.
You will need a multi meter ($30 at a hardware store) and some experience working with appliances, let me know a lot about your skill sets in those regards ***** ***** wish to continue. Know that I do this work on my own time and at my own expense unless I am successful *and only if show appreciation for my work by rating me positively.
