Common faults of refrigerator thermostat

As we all know, the finished product of any mechanical product is composed of scattered parts; from the beginning of assembly, each of their parts has a very important "mission" to complete, and their existence determines the product's Degree of operation. The product I want to tell you today is an important part of the refrigerator-the thermostat. Maybe there are many people who don't know the thermostat very well. The thermostat is a machine that controls the temperature as the name suggests. It is one of the important parts of the refrigerated cabinet, and when the temperature controller fails, the cabinet temperature will be too high and the number of startups will be frequent; the same reasoning will also cause the temperature in the cabinet to be too low and the compressor will continue to work . Will cause great damage to the cabinet and the compressor.

　　 1. The temperature sensor head of the thermostat is not in its original position, and it is loose and shifted. This will cause inaccurate temperature control, which will affect the working time of the compressor. In the long run, the compressor will be damaged by frequent switching on and off. Solution: Just fix the temperature sensor in the original position.

　　2. The contacts inside the thermostat are linked together. The main phenomenon is that the compressor does not stop. Solution: cut off the power supply of the cabinet, and repeatedly adjust the thermostat from lowest to highest, then from highest to lowest, cycle several times, then adjust to gear, and then turn on the power and compressor after 15 minutes or so It can be stopped. Then the contacts of the thermostat are separated.

　　3. The temperature sensing tube may be damaged due to its long service life or some external forces. Solution: buy a new one and replace it again. The general price is about＄ 30 .
