Hi all... Just had a repairman out to fix the A/C two days ago. A/C was running but not cooling (no frosting of coils, no clogged ducts, compressor fine, etc). Repairman stated that it was a faulty "solenoid switch" and replaced it successfully. For the last day and 1/2, A/C has been running fine... now all-of-a-sudden same symptoms as before. Anyone know if it's possible that the problem is the same solenoid switch again and if so, is there an underlying problem as to why this thing keeps breaking? A/C unit is a Payne, only 2 yrs old. Thanks in advance!
