the unit works but the compress relay isnt making
HVAC Technician: freon, Licensed A/C Contractor replied 8 years ago
The most likely cause is that the unit may be out on either a low pressure switch, high pressure switch, or faulty time delay relay. Can you verify that there is refrigerant in the system?
