What To Know
- Loose or corroded electrical connections at the compressor, breaker panel, or wiring can create resistance and cause excessive current flow, resulting in a tripped breaker.
- If the voltage supplied to the compressor is too low, it can cause the motor to draw more current, potentially tripping the breaker.
- Significant air leaks in the compressor system can reduce its efficiency, causing the motor to work harder and draw more current, leading to a tripped breaker.
Air compressors are essential tools for various tasks, from powering pneumatic tools to inflating tires. However, when a Craftsman air compressor repeatedly trips the breaker, it can be frustrating and disrupt your workflow. This blog post will delve into the potential causes behind this issue and provide detailed troubleshooting steps to help you resolve it effectively.
Causes of Tripped Circuit Breaker
1. Overloaded Circuit: The air compressor may be drawing too much current for the circuit it is connected to. This can occur when the compressor is under heavy load or when other high-power devices are operating on the same circuit.
2. Faulty Compressor Motor: A malfunctioning motor can cause excessive current draw, leading to a tripped breaker. This can be due to worn-out brushes, damaged windings, or a short circuit.
3. Undersized Wiring: The electrical wiring connecting the compressor to the breaker panel may be too thin to handle the current load. This can cause overheating and a tripped breaker.
4. Loose Connections: Loose or corroded electrical connections at the compressor, breaker panel, or wiring can create resistance and cause excessive current flow, resulting in a tripped breaker.
5. Low Voltage: If the voltage supplied to the compressor is too low, it can cause the motor to draw more current, potentially tripping the breaker.
6. Damaged Pressure Switch: A faulty pressure switch can cause the compressor to run continuously, overloading the circuit and tripping the breaker.
7. Excessive Air Leaks: Significant air leaks in the compressor system can reduce its efficiency, causing the motor to work harder and draw more current, leading to a tripped breaker.
Troubleshooting Steps
1. Check Circuit Load: Ensure that no other high-power devices are operating on the same circuit as the air compressor. If possible, move the compressor to a dedicated circuit.
2. Inspect Motor: Listen for unusual noises or vibrations from the motor. If detected, contact a qualified electrician or repair technician to diagnose and repair the motor.
3. Verify Wiring: Ensure that the wiring connecting the compressor to the breaker panel is rated for the current load. If the wiring is undersized, upgrade it to a thicker gauge.
4. Tighten Connections: Check all electrical connections at the compressor, breaker panel, and wiring. Tighten any loose screws or terminals.
5. Measure Voltage: Use a voltmeter to measure the voltage supplied to the compressor. If the voltage is consistently below the recommended level, contact your utility company.
6. Replace Pressure Switch: If the pressure switch is suspected to be faulty, replace it with a new one. Follow the manufacturer’s instructions for installation.
7. Locate Air Leaks: Inspect the compressor system for air leaks. Use soapy water or a leak detector to identify and seal any leaks.
Recommendations
Troubleshooting a Craftsman air compressor that keeps tripping the breaker requires a systematic approach to identify and address the underlying cause. By following the troubleshooting steps outlined in this guide, you can effectively resolve the issue and restore the compressor’s functionality.
Frequently Asked Questions
Q: What are some signs of a faulty air compressor motor?
A: Unusual noises, vibrations, overheating, or a burning smell.
Q: How do I know if the wiring to my air compressor is undersized?
