Questions and answers
after a minute compressor trips circui breaker mechanical bind or electricial
The Harbor Freight Tools Central Pneumatic 40400 air compressor could trip the circuit breaker after one minute due to either a mechanical bind or an electrical issue.
1. Mechanical Bind: If there is excessive friction or a blockage in the motor or pump, the compressor may draw too much current, causing the breaker to trip. This could be due to improper lubrication, a seized piston, or debris in the pump.
2. Electrical Issue: If the motor is faulty, the capacitor is failing, or there is an issue with the power supply, the compressor may overheat and trip the breaker. Using an incorrect or undersized extension cord can also cause excessive current draw, leading to overheating and breaker trips.
To diagnose, check for unusual noises, ensure proper lubrication, inspect the power source, and verify that the extension cord (if used) meets the required specifications.
