Unit number one. Recently replaced new trane rooftop package unit was not operating due to a faulty smoke detector. System is 3 ton package unit. An estimate will be provided for a replacement of the induct smoke detector. Unit number two to the left side from the front, older, Lennox rooftop package unit. This unit is not receiving proper voltage from breaker inside high-voltage panel. Breaker is a 30 amp three phase. On the roof, technician is only receiving one leg of power, indicating that there’s an issue inside the high voltage electrical panel. Technician tested the compressor and condenser fan on the roof along with other components, and would recommend having the high-voltage breaker repaired/replaced restoring power to the equipment.
