12. Condensing Unit Troubleshooting
Unit not running
1) Incorrect power supply
2) Incorrect or loose wirings
3) Failed
components
4) Low pressure control shutting down the
system
5) High pressure control 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 the condenser water flow
