What To Know
- A loose or damaged belt can cause the compressor to vibrate and make noise.
- Drain the tank regularly, especially if you use the compressor frequently or in humid environments.
- A faulty pressure switch may cause the compressor to run constantly, not build pressure, or shut off prematurely.
Air compressors are the backbone of many workshops and garages. When your trusty Craftsman air compressor starts acting up, it can bring your projects to a screeching halt. But don’t panic! With the right guidance, you can diagnose and fix the issue, restoring your compressor to its former glory. This comprehensive guide will walk you through the common problems and provide step-by-step instructions on how to fix Craftsman air compressor issues.
Common Problems and Troubleshooting
1. No Power
- Check the power cord: Ensure it’s securely plugged into an outlet and the switch is turned on.
- Inspect the fuse or circuit breaker: If the cord is fine, check if the fuse or circuit breaker has tripped.
- Test the motor: Use a multimeter to check if the motor is receiving power.
2. Compressor Not Building Pressure
- Check the air filter: A clogged filter can restrict airflow. Clean or replace it.
- Inspect the unloader valve: It may be stuck or faulty, preventing air from entering the tank.
- Examine the pressure switch: It may be malfunctioning and not activating the compressor when pressure drops.
3. Compressor Running Constantly
- Adjust the pressure regulator: It may be set too low, causing the compressor to run continuously.
- Check for leaks: Inspect the hoses, fittings, and tank for any leaks that could be causing a pressure drop.
- Examine the pressure switch: It may be faulty and not shutting off the compressor when the desired pressure is reached.
4. Excessive Noise
- Lubricate the compressor: Insufficient lubrication can cause gears and bearings to wear and make noise.
- Check the air filter: A dirty filter can restrict airflow and create noise.
- Inspect the belt: A loose or damaged belt can cause the compressor to vibrate and make noise.
5. Compressor Overheating
- Clean the radiator: Dust and debris can clog the radiator, preventing proper cooling.
- Check the oil level: Low oil levels can cause overheating and premature wear.
- Inspect the fan: The fan may be damaged or not working, preventing proper air circulation.
6. Water in the Tank
- Drain the tank: Condensation can build up in the tank. Drain it regularly to remove excess water.
- Check the air intake: Ensure the air intake is not drawing in moist air, which can contribute to water accumulation.
- Install an air dryer: An air dryer can remove moisture from the compressed air before it enters the tank.
7. Compressor Not Starting
- Check the power supply: Ensure the compressor has power and the switch is turned on.
- Inspect the start capacitor: A faulty capacitor can prevent the motor from starting.
- Examine the start relay: It may be malfunctioning and not engaging the motor.
In a nutshell: Breathe New Life into Your Craftsman
With the knowledge gained from this guide, you’re now equipped to diagnose and fix common problems with your Craftsman air compressor. Remember, regular maintenance and proper usage can extend its lifespan and keep your projects flowing smoothly.
Basics You Wanted To Know
1. What type of oil should I use for my Craftsman air compressor?
Use high-quality compressor oil specifically designed for air compressors. Check the manufacturer’s recommendations for the recommended oil type and viscosity.
2. How often should I drain the water from my air compressor tank?
Drain the tank regularly, especially if you use the compressor frequently or in humid environments. Draining the tank prevents water buildup and extends the compressor’s longevity.
3. What are the signs of a faulty pressure switch?
A faulty pressure switch may cause the compressor to run constantly, not build pressure, or shut off prematurely. It may also fail to activate the motor when pressure drops.
