The ultimate guide to resolving husky air compressor startup issues

Air compressors are essential tools for various industries and home projects, and Husky air compressors are known for their reliability and durability. However, like any mechanical device, they can sometimes encounter issues that prevent them from turning on. If you’re facing this frustrating situation, don’t worry; this comprehensive guide will help you troubleshoot the problem and get your Husky air compressor back up and running in no time.

Common Reasons Why Your Husky Air Compressor Won’t Turn On

1. Power Supply Issues

• Check the power cord: Ensure that the power cord is securely plugged into both the compressor and the power outlet. Inspect the cord for any damage or loose connections.
• Test the power outlet: Use a voltage tester to confirm that the power outlet is providing electricity. If the outlet is faulty, contact an electrician.
• Check the circuit breaker or fuse: If your compressor is plugged into a circuit breaker or fuse, make sure it has not tripped or blown. Reset the circuit breaker or replace the blown fuse.

2. Pressure Switch Malfunction

• Inspect the pressure switch: The pressure switch controls the compressor’s cycling. If it fails, the compressor may not turn on or may not maintain the desired pressure. Check the switch for any loose wires or faulty connections.
• Test the pressure switch: Use a multimeter to test the continuity of the switch. If the switch is faulty, it needs to be replaced.

3. Motor Problems

• Check the motor brushes: The motor brushes supply electricity to the motor. Worn or damaged brushes can prevent the compressor from starting. Inspect the brushes and replace them if necessary.
• Test the motor windings: Use a multimeter to test the resistance of the motor windings. If the windings are open or shorted, the motor may need to be repaired or replaced.

4. Air Filter Clogged

• Inspect the air filter: A clogged air filter can restrict airflow to the compressor, causing it to overheat and shut off. Check the filter and clean or replace it if it’s dirty.

5. Low Oil Level

• Check the oil level: Insufficient oil can cause the compressor to overheat and shut down. Check the oil level and add more oil if necessary. Refer to the manufacturer’s instructions for the recommended oil type and quantity.

6. Safety Features Activated

• Overload protection: Husky air compressors have built-in overload protection to prevent overheating. If the compressor is overloaded, it will automatically turn off. Allow the compressor to cool down before restarting it.
• Thermal overload switch: If the compressor overheats, the thermal overload switch will trip, preventing damage to the motor. Reset the switch once the compressor has cooled down.

7. Other Possible Causes

• Damaged start capacitor: The start capacitor helps the motor start. If it fails, the compressor may not turn on.
• Faulty unloader valve: The unloader valve releases pressure from the air tank when the compressor is not running. A faulty valve can prevent the compressor from starting.
• Leaking air hoses or fittings: Leaks in the air hoses or fittings can cause the compressor to lose pressure and prevent it from turning on.

Troubleshooting Steps

1. Check the power supply and power cord.
2. Inspect the pressure switch and test its continuity.
3. Examine the motor brushes and test the motor windings.
4. Check the air filter and clean or replace it if necessary.
5. Verify the oil level and add more oil if required.
6. Reset any activated safety features, such as overload protection or thermal overload switch.
7. Inspect other possible causes, such as a damaged start capacitor, faulty unloader valve, or air leaks.

Final Note: Resolving the Issue

By following the troubleshooting steps outlined above, you can identify and resolve the issue preventing your Husky air compressor from turning on. Remember to address the root cause of the problem to ensure that the compressor operates reliably in the future. If the issue persists after trying all the troubleshooting steps, it’s recommended to contact a qualified technician for further assistance.

Popular Questions

Q1. Why is my Husky air compressor not starting but humming?
A. This could indicate a problem with the motor brushes or windings. Check the brushes for wear and test the windings for continuity.

Q2. What does it mean when my Husky air compressor turns on and off repeatedly?
A. This may be caused by a faulty pressure switch or a leak in the air system. Inspect the pressure switch and check for any leaks in the hoses or fittings.

Q3. How often should I change the oil in my Husky air compressor?
A. Refer to the manufacturer’s instructions for the recommended oil change interval, which typically ranges from 500 to 1000 hours of operation.
