Does indoor or outdoor come on?Give me model on old and new thermostats and tell me what wires you put to what terminal on new

Customer: replied 1 year ago.
I don't know the old model because my staff missed place them, where do I find the model number on the thermostat? I didn't do the wiring but starting at the top going down there is 3 red wires, a yellow, a white and a green wire
Customer: replied 1 year ago.
I took the unit off it's base and on the back there are the numbers TH511001022 THEN 1618

If you have more than one red it is possible you have a two transformer system .If so they may have caused a short by the way it was wired.

I would need to know what wires went to what terminals on old thermostat to determine.

Customer: replied 1 year ago.
I don't think the wires were moved at all the new looks just like the old one

Hello, virtually no electricians have the air conditioning *controls experience to wire AC thermostats... air heat man could easily be correct and that a fuse deep inside one of the furnace's or air handlers has been blown.

If you can tell me which direction you are from the center of the nearest city I can most likely locate a well rated AC controls technician in your area with good ratings, we can go from there.
