You are able to start your air compressor easily in the fall and summer, even in the end of the spring. However, your machine become more difficult to start in the winter when the temperature drops to under 0oC. Why does it happen so?
To answer this popular question, you have to understand that air compressor motors with 120 VAC work very close to the line as it is linked to the electricity power in a 120 VAC supply circuit and the amount of energy is very essential for your compressor engine to boot and work.
In the southern and northern areas of the global, people call this phenomenon snow. If there’s snow, the weather is cold, and your air compressors become just so cold as the surrounding environment when they are placed in an cold area, like in the picture below, you should bring it out of the cold workshop and warm it up.
The compressor can’t run in condition of cold weather
Which is the reason for that? The compressor oil is the most exact answer for this problem.
If you have your best air compressors for home which belongs to the lubricated model, then what matter to oil you can imagine when the weather becomes cold? It can get more viscous, thicker, and the oil layer is thicker so it goes inactively and moves more difficultly.
The pump of the compressor is splashed up by compressor lubricating oil when it was last running, and now that oil is close to, or is frozen solid.
Therefore, your air compressor is cold, thick and maybe frozen oil. When your air compressor comes to the power available in warm temperature, it is already marginal. Another cause creating this poblem is that the machine operation could now not be optimal as it’s no longer new. Then, it may be ice up.
The extra load on the motor by the thickened oil means the motor could not turn over, you may get a fuse blown or a breaker lets go, and at last, the air compressor will not begin as the temperature is too low.
Some other problems with non-lubed Air Compressors
Many people buy air compressors which are marked non-lube, or oil-less, are definitely factory lubed – in concept of the life of the compressor – these machines don’t need oil to be able to run.
In those air compressors, however, there is still factory lube, and they have the same phenomenon. Chilled and frozen lubrication adds load to the air compressor begins circuit, often to the point where the machine are not able to start.
How to solve this problem.
The most simple way you should do is to bring your compressor indoors in a few hours and then you could start it. This method will make your machine warm up and when the compressor is warm to room temperature you can plug it into the electricity power source and/or turn it on if your devices have an ON/OFF button.
It’s just a trick to resolve this kind of problems. Of course, sometimes you are still able to start your compressors when it is cold. Besides, there are some cases as your machine can not run without problems’ temperature. You should consider this.
