If you are able read wiring diagrams attach very well focused close up, well lit photos of the wiring diagrams glued to the inside of the blower access panel on the air handler or furnace inside the house, include a photo of the printed circuit board in the same compartment where the thermostat wires connect.
I also need a photo of wiring diagram glued inside the electrical controls compartment of the outside unit...note the red warning stickers... this is dangerous for anyone even a trained tech to work on.
Use the paper clip icon at the end of the tool bar above or the 'attach files' link to the left of your send button.
It is possible that you might be underestimating the task here, training is usually 4 semesters, 20 units each at a community college then a 4 year internship working under a journeyman... there are also electronics and a mother board involved.... My risk on this end is that I can spend several hours or a day training and coaching you, at my own out of pocket expense unless you rate my work positively.
I may ask for a rating after I supply a trouble shooting mark up... then if you choose to rate my work, we can go from there without a time limit.
Let me know if that is OK with you, we can go from there.
