If you’re buying your first air compressor, understanding how to spot signs of a problem can be important. With so many internal components and unusual noises, it can be tough to narrow down the source of an issue otherwise. The good news is that when you understand some of the things that could happen with the compressor, it can simplify the troubleshooting process. Here are a few common issues you might experience along with some advice for resolving them.
Compressors are not quiet equipment, but that doesn’t mean that your new compressor should be excessively noisy. Familiarize yourself with the sounds that your compressor normally makes so that you can identify any unusual noises right away. For example, if the compressor starts to squeal, rattle or whine, it’s a pretty good sign that something isn’t right.
Shut the machine off and check the oil first. If the oil level is low, top it off. Then, turn it back on again and let it run for a minute or two. Listen to see if the added oil quiets the noise. If not, shut it off again and check the flywheel, belts and pulleys. They should all be tight. Tighten any bolts if necessary. If this doesn’t solve the problem, you’ll need to have the compressor serviced, as it could be a problem with the cylinder head.
Discoloration in the Oil
You should check the oil in the compressor on a regular basis. If that oil is hazy, creamy-colored or milky, it’s an indication of moisture problems. Water in the oil creates this reaction. It usually happens when the environment where the compressor is running is very humid. Try running a dehumidifier in the shop or moving the intake lines to somewhere drier. In addition, change the oil right away when you see this kind of discoloration.
An air compressor that knocks persistently when it’s running often has a loose flywheel or a bearing that’s going bad. This is particularly likely when the noise is rhythmic. Shut down the compressor and check the flywheel condition. It should be tight. If it’s loose, tighten the central mounting bolt. If this doesn’t stop the noise, a technician will have to check the connecting rod bearings and the main bearings inside the unit.
An air compressor is a valuable investment for most any garage or shop. This is particularly beneficial if you’re running power tools of any kind. Understanding these common signs of trouble will help you avoid complete equipment failure and protect your compressor investment.
