2:57 AMThe fan in the refrigerator has stopped working
The fan in the refrigerator has stopped working.
Symptoms of a malfunctioning refrigerator fan:
The breakdown of the fan in the refrigerator can be judged by two main signs.
1 The appearance of previously uncharacteristic noise during operation of the refrigerator
2 Complete lack of cooling in the refrigerator.
The main causes of the malfunction
The fan consists of a motor, a shaft, a propeller. Electronically controlled. The protection is in the form of a fuse. The unit is started by the defrost timer signal.
When the fan in the refrigerator does not turn on, it is not necessary to change the entire assembly. The kit consists of several parts. Some of them are repaired separately. The most common causes of breakdowns are:
1 Freezing of propeller blades. A large formation of ice and snow on the blades does not allow further rotation of the fan
2 The motor is out of order. The motor fails due to voltage drops, work at high loads. Overheating, winding defect.
3 Shaft breakage, deformation, jamming. Lack of lubrication in bearings. The problem manifests itself with natural wear or factory defects.
4 Defective control module. Chips, radio components burned out, there are oxidation on the boards.
It is possible to determine the exact malfunction only after diagnosing the refrigerator. In some cases, poor-quality plastic of the blades can become the cause of the breakdown. Some of the manufacturers save on materials that crack, break during operation and subsequently scatter into separate elements. Broken elements can block the rotation of the knot.
The No Frost system is significantly different from other cooling options. And if the refrigerator fan does not turn on, then the interior of the refrigerator will completely stop cooling. In this case, due to the absence of warm air flows, the evaporator will remain cold, and the chambers will become warm. At the same time, the compressor continues to work properly, which is why it is quite difficult to identify a breakdown.
If the fan in the refrigerator with normal freezing does not spin, the equipment will continue to work properly, since only some functions will not work:
forcing cold air flows for rapid cooling;
