Customer Question

I have a diamond york 80 and the blower will not shut off. Plus the red led light is flashing.
JA: I'll do all I can to help. How long have you been dealing with this?
Customer: I had a AC tech come about 3 weeks ago check the AC unit because it wasn't cooling. He replace the chargers in the breager box for the AC and ever since he did that the blower been running non stop. I tried to turn on the heat today and noticed that the furnace didn't turn on and that is when I noticed the red light.
