I arrived for a call back on a system I just replaced a contactor on. The issue was the outdoor unit will not turn off. I inspected the condenser and found that I had wired the condenser fan motor on the hot side of the contactor. This will shut the compressor off but not the fan motor. I corrected the wiring and cycled the system on at the thermostat vs the furnace control board. The system is cycling correctly at this time.
