A clothing chain store in LA on Santa Monica Blvd requested service for their 2nd floor area being too hot. The technician troubleshooted the #3 unit for the 2nd floor, a commercial 25 ton Trane system that had tripped the circuit breaker and had a shorted contactor. Replaced the contactor and 2 pol switch relay. Cycled system back on and monitored. Unit running again, confirmed with EMS that store has returned to set-point.
