Trouble Shooting

Contact the local service agent for help if simple troubleshooting does not solve the problems.

Note: Following phenomena are not troubles:

The murmur of water is heard when the refrigerator is working; it is a normal phenomenon as the coolant is circulating in the system. In wet season, condensation might be found on the outside of the refrigerator; it is not a trouble, which is caused by high humidity. Simply use cloth to wipe it.

Principle of Refrigeration System and Electric Circuit Diagram

Principle of Compression Refrigeration:

The principle of compression refrigeration consists of "compression", "condensation", "throttling", and "vaporization". The compression is undertaken by the compressor, the condensation is completed by the condenser, the throttling valve is executed by capillary, and the vaporization is implemented by the evaporator. When the coolant is circulating in the closed refrigeration system, the compressor sucks coolant, which has absorbed heat in the evaporator. The coolant becomes a high pressure and high temperature gas. In the condenser, it dissipates heat in the air, while the coolant is re-liquefied and throttled in the capillary, and then enters into the evaporator with low pressure. The liquefied coolant quickly boils and vaporizes into gas when the pressure suddenly drops. Meanwhile, it absorbs heat inside the refrigerator. And the compressor sucks the low pressure and low temperature gaseous coolant. It is circulating in this way up to the realization of intended refrigeration.

Circuit Diagram:

The circuit diagram illustrates the electrical connections. Key components include probes (Room high temperature probe), fan motor, overload protector, LED lamp, compressor starter (PTC TC), and power supply (220-240V~ 50Hz).
