The most common problems and troubleshooting of Haier refrigerator
1, the refrigerator door is hot.

Reason: The high-pressure pipes of the compressor are all around the door frame, and the heat of the high-pressure pipes is used to avoid condensation, so it is normal for the door to heat up.

It is normal for the refrigerator to make a strong vibration sound when it starts and stops.

The lights won't go out after closing the door.

Reason: This is because the plastic cover of the thermostat door lamp is located too inside and the position is not in place. After the door is closed, the door light switch button cannot be pressed and the light will not go out.

Troubleshooting: To solve this problem, find the fixing screw position of the plastic cover of the door light of the thermostat, loosen it and pull the plastic cover outward until the door light switch can be pushed, then tighten it, close the refrigerator door and hold the door light switch.

Extended data:

1, the thermostat can't be turned off and won't stop, which will make the temperature in the refrigerator lower and lower. If the refrigeration effect is poor and the machine does not stop, it means that the refrigerant in the refrigeration system is leaking, not the fault of the thermostat.

2, temperature imbalance is mostly caused by mechanical parts failure, long-term operation without downtime, long-term downtime is a fault phenomenon.

3, the most common thing is that the refrigerator does not start, generally the thermal protector is broken.
