Troubleshooting

Note

Certain phenomena are normal and should not be considered as faults with your freezer:

• A murmuring or gurgling sound may be heard when the freezer is running. This is normal as it's simply the coolant circulating within the system.
• In humid weather, condensation may form on the exterior of the freezer. This is also normal and not a cause for concern. It occurs due to high humidity levels. Simply wipe it off with a cloth.

Principle of Refrigeration System and Electric Circuit Diagram

The principle of the compression refrigeration system revolves around four main steps: "compression," "condensation," "throttling," and "vaporization." The process operates as follows:

• Compression: The compressor takes in the coolant, which has absorbed heat in the evaporator, turning it into a high-pressure, high-temperature gas.
• Condensation: In the condenser, the coolant dissipates heat into the air. As a result, the coolant re-liquefies.
• Throttling: This phase is executed by the capillary, which throttles the re-liquefied coolant into the evaporator at a low pressure.
• Vaporization: Upon entering the evaporator, the liquefied coolant quickly boils and vaporizes into a gas due to the sudden drop in pressure. In this phase, it absorbs heat from inside the refrigerator.

Finally, the compressor again takes in the low-pressure, low-temperature gaseous coolant. The process repeats itself in a cycle, enabling the refrigerator to maintain its cool temperature.

A diagram illustrates the refrigeration cycle with components like drying filter, capillary device, compressor, evaporator, liquid, and gas, showing high pressure and high temperature gas, and low pressure gas.
