Air compressors are a great addition to any shop, but when they stop working it can be frustrating. One of the most common problems with air compressors is a bad start capacitor. This component serves the compressor start-up, and if it’s not working properly the compressor won’t run at all. Luckily, replacing a start capacitor is a relatively simple task that you can do yourself. With a few tools and some patience, you should be able to get your air compressor up and running in no time at all. How to Replace a Start Capacitor on an Air Compressor: The Significant StepsIf your air compressor won’t start, there’s a good chance that the start capacitor is the problem. During the normal use of the compressor, the startup capacitor may break down over time due to normal wear and tear or it may stop working if it becomes too hot. Before you begin, it’s important to gather the proper tools. You’ll need a screwdriver, a wire stripper, and a new start capacitor. You can purchase a replacement capacitor at most hardware online stores. Once you have the necessary tools, follow these steps to replace the start capacitor on your air compressor: 1. Disconnect the Power:As a first step, make sure that the air compressor is unplugged from the power source. Once the power is disconnected, you can begin working on the compressor. It is a wise idea to also wear safety glasses to protect your eyes. 2. Remove the Cover:The next step is to remove the cover from the air compressor. This will give you access to the start capacitor. In the event that the cover has been removed, locate the capacitor on the board and remove it from the wires. 3. Strip the Wires:Using a wire stripper, strip about ½ inch of insulation from the end of each wire. It’s important to be very careful when you’re doing this so you don’t damage the wires. Just a small nick in the wire can cause major problems. 4. Connect the Wires:Now it’s time to connect the new capacitor. Take a black wire from the capacitor and attach it to the black wire connected to the air compressor. Do the same with the white wires. As soon as you have connected both wires, you can screw on the cover and plug in the compressor. 5. Test the Compressor:To test the compressor, turn it on and see if it starts up properly. If it does, then you’ve successfully replaced the start capacitor. If not, then you may need to consult a professional for help. These are the basic steps you need to follow in order to replace the starter capacitor on an air compressor. Tips for Maintaining Your Air CompressorTo keep your air compressor in good working condition, there are a few things you can do.
By following these tips, you can maintain the performance of your air compressor and extend its lifespan. ConclusionNow that you have the knowledge to replace an air compressor start capacitor, instead of paying a mechanic to do it for you, it is possible to do it yourself and save some money. Just be sure to follow the steps carefully and have the right tools for the job. Just by following the steps in this article, it should be achievable to start using your air compressor in a few minutes. Thanks for reading.
