DIY Fix: Troubleshooting Your Craftsman Air Compressor Not Working Issue

If you're a DIY enthusiast or a professional, a Craftsman air compressor is a valuable tool in your arsenal. However, like any mechanical device, it can encounter issues that prevent it from working correctly. In this article, we'll explore common problems that can cause your Craftsman air compressor to fail to start, and provide step-by-step troubleshooting solutions to get it up and running again.

Possible Causes of Your Craftsman Air Compressor Not Working

1. Power Supply Issues
2. Faulty Wiring
3. Clogged Air Filter
4. Low Oil Level
5. Faulty Relay or Contactor
6. Faulty Pressure Switch
7. Faulty Safety Valve
8. Faulty Pressure Relief Valve

1. Power Supply Issues

Before diving into the more complex issues, it's important to check the power supply. Here's what you can do:

• Check the Power Cord: Ensure that the power cord is not damaged and is properly plugged into an outlet.
• Check the Outlet: Make sure the outlet is functioning correctly by plugging in another device.
• Check the Breaker/Fuse: If you have a circuit breaker or fuse box, check to see if the breaker has been tripped or if a fuse has blown.

2. Faulty Wiring

Faulty wiring can be a serious issue and should be addressed by a professional if you're not confident in your electrical skills.

• Inspect the Wiring: Look for any signs of damage or loose connections.
• Test the Wiring: Use a multimeter to test the wiring for continuity.

3. Clogged Air Filter

A clogged air filter can restrict airflow and cause your compressor to overheat or fail to start.

• Clean or Replace the Air Filter: Depending on the type of filter, you may need to clean it with a damp cloth or replace it with a new one.

4. Low Oil Level

Low oil levels can damage your compressor and prevent it from starting.

• Check the Oil Level: Refer to your Craftsman air compressor manual for instructions on how to check the oil level.
• Add Oil: If the oil level is low, add the appropriate type of oil to the compressor.

5. Faulty Relay or Contactor

A faulty relay or contactor can prevent your compressor from receiving power.

• Inspect the Relay or Contactor: Look for any signs of damage or wear.
• Test the Relay or Contactor: Use a multimeter to test the relay or contactor for continuity.

6. Faulty Pressure Switch

The pressure switch is responsible for turning the compressor on and off. If it's faulty, your compressor may not start.

• Inspect the Pressure Switch: Look for any signs of damage or wear.
• Test the Pressure Switch: Use a multimeter to test the pressure switch for continuity.

7. Faulty Safety Valve

The safety valve is designed to release pressure if it becomes too high. If it's faulty, it may prevent your compressor from starting.

• Inspect the Safety Valve: Look for any signs of damage or wear.
• Test the Safety Valve: Use a multimeter to test the safety valve for continuity.

8. Faulty Pressure Relief Valve

The pressure relief valve is responsible for releasing excess pressure from the compressor. If it's faulty, it may prevent your compressor from starting.

• Inspect the Pressure Relief Valve: Look for any signs of damage or wear.
• Test the Pressure Relief Valve: Use a multimeter to test the pressure relief valve for continuity.

Conclusion

Troubleshooting a Craftsman air compressor that's not working can be a daunting task, but by following these steps, you can identify and resolve common issues. Remember to always consult your compressor's manual for specific instructions and to ensure your safety. If you're not confident in your ability to perform these tasks, it's best to seek the help of a professional. With a little patience and determination, you can get your Craftsman air compressor up and running again in no time.
