We received an EMS report regarding a customer in LA that showed one HVAC unit offline, and onsite staff reported a unit icing over. Upon arrival, our A/C technician inspected the commercial Carrier unit and found no high voltage and the main breaker tripped. Determined that a shorted crank case heater had caused the voltage loss. Will quote necessary repairs to the customer. Confirmed with EMS that all other units are operating normally.
