The Most Common Causes of Your Air Compressor Humming
You've suddenly got a humming air compressor. What's the deal with that? If your air compressor hums instead of starting up, it's trying to tell you something.Humming air compressors indicate a problem. When it comes to equipment, humming usually indicates an electrical problem. You can get to the bottom of an air compressor hum with a little troubleshooting. In many cases, you can even resolve your problem right away.Not Enough Power
Compressors are extremely portable, and you can take them wherever you need to go as long as you have access to power. If you need to work away from a power source, make sure you have an extension cord that is rated for the task.The gauge of extension cords varies. The lower it is, the better the cord is suited for heavy-duty and outdoor applications. Higher gauge wires (typically 14 and above) can cause power draws that cause your air compressor to hum.An Unloader Valve That isn't Working Properly
Excess pressure in the tank is relieved by unloader valves. If your unloader valve traps air inside your compressor, the stress on the motor will cause it to fail. The air compressor will hum if the motor cannot start due to excessive air buildup.Turn off your compressor to troubleshoot it. Empty the tank with the hose to relieve pressure. Start the compressor. If the compressor motor starts but does not hum after draining the tank, your unloader valve is most likely to blame.Filters in the intake system are clogged.
Air compressor intake filters keep dirt and crud out of your machine. But the trapped media accumulates over time and restricts airflow into the motor. Compressors will stall if there is insufficient air, and this is the thing that causes your compressor to hum when you try to restart it.Unscrew and remove your air filter to see if it is the cause of your air compressor humming, then restart your machine. If it works, your filter needs to be cleaned.Blocked Tank Check Valve Needed to Clean
Blocked valves stop the air inside your tank or compressor header from coming back through the inlet line after shutdown. Damage can occur if the valve becomes stuck open. If it is held closed, it can cause a pressure increase, which frequently results in your air compressor humming.Tank check valves are typically attached to the tank near the point where the pump-head line connects. Remove yours and clean the valve of any debris. If the check valve isn't working properly, it's usually just a matter of cleaning. Rinse several times with a clean solvent, allow to dry completely, and reassemble. If cleaning the tank check valve does not improve its performance, it should be replaced.Capacitor Problem
Compressors require a lot of power. Capacitors inside these machines provide the extra energy required to start your compressor. These devices function as batteries, storing electricity.They will, like batteries, eventually reach the end of their useful life. They can also lose function much faster if they are damaged by a voltage spike, corrosion, or high temperatures. In this case, you should contact a professional repair service or replace your compressor.Contact All Air Compressors To Deal With Your Air Compressor Issues In Sydney!
