Hello,

Take close up, exceedingly well focused photo's of the wiring diagram glued inside the furnace/air handler door, and the printed circuit board mounted on the blower, , that shows where the thermostat wires connect, and I will mark them up with trouble shooting instructions.

Use the 'add files' link next to your send button to get the photo(s) to me.

We can go from there with training, coaching and diagnosis.... without a time limit, In depth with as much detail as needed.

My goal is to give you the best experience possible! I hope I have earned a 5 star rating! Please remember to rate my service by selecting the 5 stars at the top of the screen before you leave today. If you need more assistance, please use the reply box and let me know.

We can go from there
