I arrived for 2 no a/c systems working . Both blowers run on the inside units. I started with the 2nd floor system in the attic . The filter is fine, the blower is running and we’re getting a call for 24 volts from the indoor to the AC from the thermostat outside . I have a call for my thermostat wire coming into the board for cooling outside from my y and c . I did find that I don’t have a call for 24 volts between my c and r . R will power the board. The system has good pressure, I checked all my low and high pressure switches. I jumped them off the board individually and found good. I went to the attic and found the wire was broken for the r going outside. I repaired the wire and replaced in the wire nut for the reds. Now I have a power light on the board. The a/c is back up and running for the 2nd floor . have 240 V power and I got 24 from the call for AC to the board . I’m highly recommending for the AC to be replaced in the near future. 1st floor system. 1st floor system
