Upon inspection found system has 24v but is not sending it to the thermostat. Tech found board with burn marks. Replace board and further diagnose. Additional quotes may be required, cannot fully diagnose until unit is operational. **Fuses will call JS henderson, can only get 2 right now as fuses are backordered** Arrived on site and checked in with BRINCO and mod Brittany. Removed both bad fuses from rtu 2 breaker and installed new ones. Went to roof and verified power. Turned on disconnect and jumped unit using test. System started up tech found circuit one compressor had no amps even though the contactor was pulled in. Put hand on compressor and could feel the scroll making small rotation then stopping and trying agian. Tech turned off disconnect and ohmed out compressor found all the windings open. Left compressor wires disconnected and insulated so that system could run on one compressor till new one could be ordered. Will need to quote out a new compressor and to replace unit
