The condensing unit was not operating upon arrival. I found the outdoor fan motor had overheated and shut down and the compressor went out on IP. The capacitor for the outdoor fan motor tested good. The unit was displaying a low charge and I found oily residue on the suction king valve. I did a brief check for leaks and did not find a leak around the valve but the service ports are leaking Freon. The homeowner said the unit has been struggling for a long period. I replaced the 1075 outdoor fan motor and replaced the service valves. I charge the unit back to factory specifications.
