. How to identify the 3 terminals on the casing of a hermetic compressor?<br></br> The resistance between running terminal (R), starting terminal (S), common terminal (C), RS is greater than the resistance between SC and RC. The resistance between RS is equal to the resistance between SC and the resistance between RC.

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="magefan_blog/What_is_the_cause_of_refrigerator_compressor_not_working.jpg"}}" alt="" />

Compressor: It is a complex machine running at high speed. Ensuring adequate lubrication of moving parts such as compressor crankshafts, bearings, connecting rods, pistons, etc. is the basic requirement for maintaining the normal operation of the machine. For this reason, compressor manufacturers require the use of specified grades of lubricating oil, and require regular inspection of the lubricating oil level and color

Symptoms of refrigeration system failure 1. Detection of pressure and temperature of refrigeration system (1) The pressure concept of the refrigeration system The refrigeration system can be divided into high and low pressure during operation. The high pressure section is from the discharge port of the compressor to before the throttle valve. This section is called the evaporation pressure.
