Compressor fridges are essential appliances in homes and commercial environments, responsible for keeping food and drinks fresh. However, as they are used for longer, they may fail. Understanding common causes of failure and how to troubleshoot them will help users solve problems in a timely manner and extend the life of the fridge.

Common causes of failure
Decreased cooling effect

Causes: compressor failure, insufficient refrigerant, dirty condenser, etc.
Troubleshooting method: Check whether the compressor is operating normally, observe whether the condenser is covered with dust, clean the condenser if necessary, and detect whether the refrigerant is leaking.
The refrigerator is noisy

Causes: The compressor is not working properly, the fan is faulty, or the refrigerator is not placed stably.
Troubleshooting method: Confirm that the refrigerator is placed stably, check whether the compressor and fan are operating normally, and if there is any abnormal sound, further check whether there are loose parts.
Frost in the refrigerator

Causes: Damaged door seal, thermostat failure, or fan problem.
Troubleshooting method: Check whether the door seal is tight to ensure there are no gaps; test whether the thermostat is set correctly; observe whether the fan is operating normally to ensure air circulation.
The refrigerator cannot start

Reason: power failure, compressor overload protection or circuit problem.
Troubleshooting method: Check whether the socket and power cord are normal to confirm whether there is electricity; if the compressor is difficult to start, you may need to wait for it to cool down before trying again. If there is still no response, it is recommended to contact professional maintenance.
The temperature inside the refrigerator is uneven

Reason: Improper thermostat setting and unreasonable placement of internal items.
Troubleshooting method: Check whether the thermostat is set appropriately to avoid items blocking air circulation and ensure that the cold air can be evenly distributed.
Repair and maintenance suggestions
Regular cleaning: Clean the condenser and interior of the refrigerator regularly to prevent dust accumulation.
Keep ventilation: Make sure there is enough ventilation space around the refrigerator to prevent overheating.
Regular inspection: Check the door seals and thermostat regularly to ensure that they are operating normally.
Professional maintenance: If there are complex problems or you cannot troubleshoot them yourself, it is recommended to contact professional maintenance personnel for inspection.
