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="" />
