How to judge the starter of the refrigerator compressor is broken Types of refrigerator compressor starters 1. The heavy hammer starter, the part that is easily damaged is the poor contact of the start contact. During the measurement, the weight starter can be removed and measured with a multimeter ohm block according to the original installation direction. The starting contact resistance should be infinite; turn the weight starter 180°, and the starting contact should be in good contact. 2. PTC magnetic disc starter, the part that is easily damaged is the magnetic disc overheating damage. During the measurement, the PTC magnetic disk starter can be removed and the magnetic disk in the magnetic disk starter can be taken out. Under normal circumstances, the resistance between the two planes of the PTC magnetic sheet is more than ten ohms at room temperature, and the resistance value in the hot state (heating the PTC magnetic sheet while measuring) is infinite.
How to judge the starter of the refrigerator compressor is broken If it is a PTC starter, it can be measured by the resistance file R×1 ohm of the multimeter. The M and S holes should have a resistance of more than 10 ohms to 20 ohms. If the resistance is found to be infinite, it means that it is damaged; if it is The heavy hammer starter is also measured with the multimeter's resistance file R×1 ohm. Put the starter vertically, the coil is below, and the red and black test leads are inserted into the starter M and S holes. The starter is reversed and the coil is vertically above. At this time, it should be in closed communication. If it still fails, it means that it is damaged. Then measure the M and S holes and the output end should be in closed communication. If it fails, it means that the coil is damaged.
Why is the refrigerator starter broken Why would the refrigerator starter break? It may be that the exhaust port of the compressor in the refrigerator is leaking, causing the refrigeration effect of the refrigerator to be too low, and then the refrigerator cannot be cooled normally. It may be that the refrigerant in the refrigerator is not enough, which causes a problem in the internal cooling of the refrigerator. Even if the temperature inside the refrigerator has fallen, it cannot be stabilized. Either the electric shock on the temperature controller of the refrigerator has a poor contact phenomenon, which will cause the compressor of the refrigerator to appear irregular and frequently operate. It may also be that the temperature control range of the refrigerator temperature controller is too small, causing the temperature inside the refrigerator to drop slightly before disconnecting, so that the compressor of the refrigerator will be operated frequently. Either the voltage that the refrigerator is connected to is not stable enough, and the instability of the general voltage will also cause the refrigerator to stop itself for a while, and then turn on again by itself. Anyway, if there is a problem with the starter of the refrigerator, it will definitely affect the normal operation of the refrigerator. Because it is difficult to find the cause of the failure of the refrigerator starter, it is better to require professional personnel to judge. And after determining the cause of the failure of the refrigerator starter, it also needs to be repaired. It is estimated that it is impossible to operate in our own words, so it is better to ask a professional master to judge at the beginning, and then the repair will be better. . It always costs money, and we can still make it easy, which is also better.
