10. Condensing Unit Troubleshooting
Unit not running
1) Incorrect power supply
2) Incorrect or loose wirings
3) Failed components
4) Low pressure switch shutting down the
system
5) high pressure switch shutting down
the system
1) Check for proper voltage
2) Check
all
wirings
and
connections
3) Check start relay, start capacitor, overload
protector, compressor.
4) Check for system restriction or low
refrigerant
5) Check for the condenser fan
