Arrived and inspected the condenser to determine if there was an issue when the boards were replaced. Could not determine why the unit was not operating when there was signal for heat and high voltage. Replaced the boards again per York and had the same results. Tested the fan motor and compressor to determine if either were shorted to ground, neither were. Closed the service valves, recovered the remaining refrigerant in the line set, and replaced the condenser. Weighed in the additional refrigerant of 12 ounces and operated the system in heating and cooling, the condenser ran with no issues.
