What To Know
- If the compressor is connected to a circuit breaker or fuse, it may have tripped or blown.
- The pressure switch is responsible for turning the compressor on and off based on the air pressure in the tank.
- If the compressor is making strange noises, such as grinding or squealing, it could indicate a motor issue.
A Craftsman air compressor is a valuable tool for many homeowners and professionals alike. However, when this essential equipment fails to operate, it can be a frustrating and time-consuming experience. If you find yourself asking the question, “Why is my Craftsman air compressor not working?” this comprehensive blog post will guide you through a series of troubleshooting steps to help you diagnose and resolve the issue.
Common Causes and Solutions
1. Power Supply Issues
- Check for a loose or disconnected power cord. Ensure that the cord is securely plugged into both the compressor and the power outlet.
- Verify that the power outlet is functioning. Plug another device into the outlet to confirm that it has power.
- Reset the circuit breaker or fuse. If the compressor is connected to a circuit breaker or fuse, it may have tripped or blown. Reset the breaker or replace the fuse.
2. Pressure Switch Malfunction
- Inspect the pressure switch. The pressure switch is responsible for turning the compressor on and off based on the air pressure in the tank. Look for any loose wires or damaged components.
- Adjust the pressure switch. The pressure switch may be set incorrectly. Refer to the compressor’s manual for instructions on how to adjust the switch.
- Replace the pressure switch. If the switch is damaged or malfunctioning, it may need to be replaced.
3. Motor Problems
- Listen for unusual noises. If the compressor is making strange noises, such as grinding or squealing, it could indicate a motor issue.
- Check for overheating. Touch the motor to see if it is excessively hot. Overheating can damage the motor.
- Lubricate the motor. The motor may require lubrication. Refer to the compressor’s manual for the recommended lubricant and lubrication schedule.
4. Air Leaks
- Inspect the hoses and fittings. Check for any leaks or loose connections in the air hoses and fittings. Tighten any loose fittings and replace any damaged hoses.
- Use soapy water to detect leaks. Apply soapy water to the hoses and fittings. If bubbles appear, it indicates a leak.
- Repair or replace the leaky component. Once you have located the leak, repair or replace the affected component.
5. Tank Issues
- Drain the tank. Condensation can accumulate in the air tank over time. Drain the tank to remove any water or debris.
- Inspect the tank for damage. Look for any rust, dents, or cracks in the tank. A damaged tank can be dangerous and should be replaced.
- Clean the tank. If the tank is dirty or contaminated, it may need to be cleaned. Use a mild detergent and water to clean the tank.
6. Other Possible Causes
- Check the air filter. A clogged air filter can restrict airflow and cause the compressor to overheat. Clean or replace the air filter as needed.
- Inspect the unloader valve. The unloader valve releases pressure from the tank when the compressor is turned off. If the valve is malfunctioning, it can prevent the compressor from building pressure.
- Look for any loose or damaged wires. Loose or damaged wires can disrupt the electrical circuit and prevent the compressor from operating.
Troubleshooting Tips
- Refer to the compressor’s manual. The manufacturer’s manual provides detailed instructions and troubleshooting tips specific to your model.
- Contact Craftsman support. If you are unable to resolve the issue on your own, contact Craftsman support for assistance.
- Consider professional repairs. If the problem is complex or requires specialized knowledge, it may be necessary to seek professional repairs.
