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="" />

Which refrigerator is better for cooling

Different cooling methods of refrigerators have different advantages, mainly depending on which cooling method is selected. The direct cooling refrigeration type is cheap, relatively energy-saving, and has good fresh-keeping and moisturizing properties, but the temperature is uneven, and it needs to be defrosted frequently.

Bearing and shaft fit tolerance standard

Bearing and shaft fit tolerance standard ①When the bearing inner diameter tolerance zone and the shaft tolerance zone form a fit, the tolerance code originally belonging to the transition fit in the general basic hole system will become an over-win fit, such as k5, k6, m5, m6, n6, etc., but the over-win amount is not Large; when the bearing inner diameter tolerance is matched with h5, h6, g5, g6, etc., it is not a clearance but an over-win fit.
