Why is the car refrigerator light flashing and not cooling?

[StAngela]

The reasons why the car refrigerator is not cooling may include the power socket not being properly connected, voltage below 187 volts, or the refrigerator's low-temperature switch not being turned on. Here are the relevant explanations: 1. Check if the power connection is normal: Open the refrigerator door and observe whether the interior light is on, or use a test pen to check. If the power connection is normal, listen to see if the compressor is working. A normally operating compressor will emit a slight vibration and motor sound (if you touch the compressor to feel the vibration, be careful not to get burned, as the compressor temperature can reach 40-50℃ in winter and 80-90℃ in summer). 2. No refrigerant: If the compressor can work, check whether there is refrigerant (commonly known as coolant) in the refrigeration system. Let the refrigerator run for a few minutes, then unplug it and listen carefully for the sound of liquid flowing in the copper pipes. If there is no sound, it means the refrigerant in the system has leaked, or the compressor has lost its working ability.
