Arrived to found unit not working I was receiving 24 V at the thermostat but I was not at the outdoor unit I did a hard reset and the air handler came on but the condensing unit did . diagnosed as a bad defrost board and contactor need to order the defrost board. I took pictures of the data plate on the condensing unit and the air handler unit. It is unit number two. The other systems are working at this time. Also, on the air handler unit, the float switch was wired up, but the wires were outside of the unit instead of run through where the power supply goes, crimping the float, switch wires float switch and wired it up properly. Need to order defrost board for the condensing unit.
