What is the cause of refrigerator compressor not working

What is the cause of refrigerator compressor not working Ambient temperature is too low: it is more difficult to recover, the compressor cannot work for a long time, the compressor oil becomes thicker, and the lubrication performance will be worse; PTC starter failure: if the PTC starter is damaged, you can replace it Overload protector failure: failure occurs, replace it; compressor internal failure: determine that the compressor holds the shaft and replace it. <img src="{{media url=&quot;magefan_blog/What_is_the_cause_of_refrigerator_compressor_not_working.jpg&quot;}}" alt="" />

Introduction to the principle of electric screw machine

One. The electrical control system of the microcomputer controller electric screw air compressor is the key system of the electric screw compressor. Its main function is to reduce the voltage and reduce the starting current when the three-phase asynchronous motor (capacity is greater than 10KW) is started, so as not to generate excessive power in the power supply line. Voltage drop to reduce the impact on the grid.
