Trane XL19 clicking noise
I have a XL19 unit making a clicking noise emitting from the defroster board CNT04335, and the red led is flashing twice per second.
The unit had leaked freon, located and repaired yesterday. Recharged system with 17 pounds as noted on panel, with good pressures. Noticed compressor unit was cycling more then normal along with the clicking and led flash. Bad defroster board?
