Compressor is Running Continuously
The function of compressor in a refrigeration system is to act as a pump to circulate the refrigerant in the cooling circuit. It can happen that to maintain the cooling temperature in the rooms, the compressor is running continuously. If this happens following can be the causes for the same :
| Reasons | Solutions |
| Refrigerant not sufficient for cooling evaporator. | Ensure thermostatic expansion valve is working properly and clean the filters inside TEV. |
| Thermostat low pressure cut-out not activated at low temperature/ pressure. | Correctly set the LP cut-out to correct setting. |
| Refrigerant charge is low in the circuit. | Check for leakage of refrigerant and charge with required refrigerant. |
