Troubleshooting

|
---|---
No Refrigeration

Describes a refrigerator that completely fails to cool or maintain the desired temperature inside.

| ▪  Check if the plug is properly inserted into the socket.

▪  Verify if the fuse is intact.

▪  Ensure there is power supply.

Unsatisfactory Refrigeration

Describes a refrigerator that is working but not cooling to the expected or set temperature.

| ▪  Check if the refrigerator is placed under direct sunlight or near any heat source.

▪  Ensure good ventilation in the surrounding area.

▪  Verify if the door is properly closed or has been left open for a long period.

▪  Inspect the door seal strip for any deformity or damage.

▪  Check if the refrigerator is overloaded or congested with food.

▪  Ensure food items do not block the air suction or outlet.

▪  Adjust the temperature controller as needed.

Excessive Noise

| ▪  Check if the refrigerator is level.

▪  Verify if the refrigerator is in contact with a wall or another object.

▪  Check for any loose parts in the refrigerator.

Note

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

• A murmuring or gurgling sound may be heard when the refrigerator 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 refrigerator. 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.

Major Parameters

Note

• If there have been any changes, the final electric circuit diagram and parameters are those stated on the product nameplate.
• The design may be improved without prior notice.

WARNING The refrigerator uses R290, a flammable refrigerant. Please take precautions against fire.

Disposal Instructions

• The crossed-out wheeled dustbin symbol indicates that electrical appliances should not be disposed of as unsorted municipal waste. Instead, utilize separate collection facilities.
• For information regarding the available collection systems, contact your local government. If electrical appliances are improperly disposed of in landfills or dumps, hazardous substances can leak into the groundwater and enter the food chain, posing risks to health and well-being.

When replacing old appliances with new ones, check with your retailer about any haul-away or recycling programs they may offer for your old appliance. Remember to also check local regulations and available recycling programs in your area to ensure proper disposal.
