![]() ![]() Improper mounting - A further cause of noise is when the compressor is mounted loosely.Take out the cylinder head and check for dirt on the piston, then replace the gasket and reattach the head. Problem pistons - Noise also occurs when the piston hits the valve plate.Check to see whether the crankcase needs new oil or bearings, or if it needs to be replaced outright. Troubled crankcase - Another common noise culprit is the defective or oil-deficient crankcase.Check for looseness in the pulleys, cooler, flywheel, clamps, belt, accessories, etc. Loose parts - Noise is often the result of loose internal parts.When a reciprocating type air compressor makes loud noises that seem obnoxious and out of character, it’s likely due to one of the following, easily corrected issues: You will be able to identify a leak by bubbles forming at the point of leakage. Then, take a solution of dish soap and room temperature water and brush it onto each compressor and the coupler end. First, pull the hose away from the compressor coupler. If you cannot pinpoint the leak visually or by listening for it, try soaping the compressor’s connections. Feel for the leak - You may be able to feel the air leak with your fingers by running them along the hoses and other components.Listen for the leak -If the air leak is bad enough, you will be able to hear a hiss where the air is escaping.To try and find the leak, do the following. If you plug in the compressor, the pressure switch response to the air leak and dropping compressor pressure will be to start the compressor again. If you shut down the compressor when the tank is filled with air and then find that the pressure gauge is showing a drop in pressure, you know that the compressor is leaking air. With compressors, operation failure could stem from one of the other issues covered in this air compressor troubleshooting guide. In most cases, however, the failure could be simply caused by oversights like an unturned switch, a lack of fluid or an unplugged cord. When you’re used to a machine working and one day it fails to power on, the experience can be quite shocking. Pressure disparity - If the tank pressure is too low in relation to the cut-in pressure, replace the pressure switch for one with reduced cut-in.This can possibly be remedied with adjustments to the pressure switch. Power switch failure - When the compressor fails to power on, it could be due to a lack of contact between the pressure switch and inner circuitry.If your compressor is failing to work properly, it could simply be from a nearly empty oil tank. Lack of oil - Users sometimes forget to check or change the fluids, and the consequences are often grievous.No power - If the compressor lacks electrical power, check the power button and activate the reset switch if needed.The most common problems can be remedied as follows: Fortunately, operational issues are among the easiest problems to diagnose and remedy on air compressors. If a compressor fails to operate, it’s usually caused by a basic problem or simple oversight. The following air compressor troubleshooting tips can help solve some of the most common problems that are known to occur with air compressors. However, any piece of equipment may fail from time to time, leaving you wondering, “What’s wrong with my air compressor?” Whether there’s a problem with the motor, lubricant supply or pressure, the issue needs to be remedied before it spirals into a costly repair. While compressed air is relied upon for heavy-duty tasks that would otherwise require tremendous manpower, a compressor will sometimes require regular maintenance to ensure proper operation. The air compressor is a powerful machine that, in today’s high-tech world, is used by everyone from auto mechanics to furniture makers, in addition to manufacturers large and small. ![]()
