Haier refrigerator always drips water, which means the door is not closed properly.

The refrigerator door is not closed properly. It may be that there is a gap in the back door after closing the door, and the rubber sealing ring is not stuck or dropped, resulting in the door not being closed tightly. It is also possible that the switch sensor of the refrigerator has been replaced and the alarm has been falling. There is something wrong with the main circuit board of the refrigerator, and a circuit of the alarm and sensor is out of order. 1, to find out the cause of the problem, first of all, you can put your hand on the edge of the car door and carefully feel whether there is chill or cold air flowing out. If the sealing ring is aged or damaged by violence, it may be deformed. Sealing ring and magnetic stripe are the key points to close the refrigerator door. If there is a problem, it is difficult to tighten the door, and it is necessary to measure and replace the rubber ring. 2. But if there is no air conditioner, it should be that the alarm is broken. Check whether the current of the switch inductor is normal. Whether the sensor fails due to cold or not, you can replace it with a new sensor. 3. There is something wrong with the main circuit board of the refrigerator, and a circuit of the alarm and sensor on the main circuit board is out of order. Observe whether the cooling effect of the air conditioner is normal. If there are abnormal ultra-low temperature, alarm and sensor suppression circuits, if the interior lights are not on, then these problems may have occurred. Remove the circuit board for maintenance. If it is difficult to maintain, just replace the new circuit board.
