Cruisair Marine Air Conditioner Troubleshooting
Trouble | Probable Cause | Symptoms | Remedy |
---|---|---|---|
Compressor fails to start | Power source failure | No current at power source | Check for tripped circuit breaker |
Faulty switch assembly | No current at condensing unit terminal strip | Check for faulty switch | |
Low voltage | Compressor tries to start & then cuts off | Correct power source | |
Faulty high pressure switch | Voltage to switch but no voltage between the switch and compressor | Replace high pressure switch | |
Faulty compressor | Unit draws locked rotor amp. (locked rotor amp found on data plate) | Replace compressor | |
Compressor cycles every 15 to 30 seconds | Low voltage | Compressor's thermal overload opens | Correct power source |
Incorrect refrigerant charge | Excessive head pressure | ||
Restricted condenser air flow | Excessive head pressure. High pressure switch opens | Correct condenser air flow | |
High pressure switch incorrectly set | Switch opens before 425 psig head pressure | Replace high pressure switch | |
System not cooling | Switch assembly not set properly or thermostat satisfied | Ventilation operation only | Set switch and thermostat at correct selection |
No or restricted air flow | Compressor cycles quickly | Check for restricted condenser air flow | |
System low on refrigerant | Compressor suction line warm | Check refrigerant charge | |
Thermostat satisfied | Compressor runs for short time and then cycles off | Reset thermostat to desired level. Calibrate if necessary | |
Iced cooling unit | Restricted air flow | Restricted discharge air flow | Clean return air filter & check for airflow restrictions |
Low refrigerant charge | Compressor suction line warm | Check refrigerant charge | |
Blower or fan motor inoperative | Power source failure | No current at power system | Check for tripped circuit breaker |
Low voltage | Hot motor. Motor thermal'electric protector open | Check power source | |
Faulty switch assembly | No power to motor | Replace faulty switch | |
Cooling unit throwing water out of discharge grill | Blocked or restricted condensate drain | Excessive water out of discharge grill | Check for condensate drain restrictions |
