Performed diagnostic on the system and found that the primary drain line has clogged. This tripped the water safety switch and shut off the outdoor unit. I also found that the outdoor condenser fan motor is showing signs of overheating. I presented my findings to the homeowner, and she chose to have the drain cleared today only. I cleared the drain line and tested it with two gallons of water. I also taped down some insulation on the air handler panel. I wiped down the system and glued the secondary drain back together since it had come apart. I ran the system for 15 minutes and it is now draining properly. System operational.
