Unit 605. Today it was tripped out on high pressure. I took a air compressor with a different nozzle and blue from the inside out through the condenser coil to clean it. Checked capacitor on both condenser fan motor and blower motor and amp draws and everything was within range. Due to the height of the room we cannot access the outdoor panel to clean coil deeply. System ran for over an hour and took the temperature from 81 to 70 and satisfied and shut down. At this time this unit is running as it should be. Also helped steve out with three other units running item up and down to make things easier.
