How to Fix an Air Compressor Outside That Stopped
Air compressors are typically long-lasting tools that require little maintenance. When a compressor that has been functioning suddenly stops, the cause is usually related to several common issues. Compressors need electricity to run the motor, a sealed tank to hold the pressure and a clear air way to deliver the compressed air to your tools. Troubleshooting these three will typically provide a solution. Since pressurized tanks are potentially hazardous, any compressor that does respond to these steps should be professional repaired. Does this Spark an idea?

Check to be sure that the air hose is connected properly to your tool and to the compressor, and that any stopcocks in the line are turned to the open position to allow free flow of air. Trace the line outside to the compressor and check each fitting, reconnecting fittings or opening closed valves.

Check to see that the electric power switch is on at the compressor. If not, switch it to the "On" position. If the compressor returns to its normal function, return to normal use, if not, check the reset button. This is a small black or red button on the back or bottom of the compressor motor, designed to prevent overheating. Depress this button. If this doesn't work, try releasing the pressure to kick the compressor on. Look for a small metal/ plastic valve with a ring through it. Pull out this ring to release the spring-loaded valve and let air out. Once it falls below the threshold setting, it should kick back on. If not, proceed to the next Step.

Open the gas cap on gas-driven compressors. Check to see if the tank has fuel. If not, fill and restart. Check the air filter, typically located behind a plastic grill on top of the motor. Clean a dirty filter with paint thinner, and allow it to dry before returning it and restarting the motor. Use a spark plug wrench to remove the plug and check for a blackened end; replace a worn plug and restart.

Check the cord on electric compressors to be sure it is plugged in. Trace any extension cords back, checking each connection to the wall plug and ensure that the plug is correctly inserted. If the power supply seems intact but the compressor still does not come on, check your home's breaker box to see if any circuit breakers are tripped. Look for breakers with a small red square in the indicator window. Flip the breaker off and on to make certain it is reset and check the compressor for proper function.

Test the outlet by plugging in a small radio or lamp that you know is functional. If it works properly, remove any extension cords between the compressor and the wall outlet and plug it in directly to an outlet and turn it on. If it comes on, replace the extension cord.

Tighten the valves and check for leaks if your compressor comes on but does not fully charge. Adjust the air regulator to the correct pressure level. Adjust the lower threshold by turning the set screw, located near the regulator. This screw will have a plus and minus sign near it. Turn this screw to adjust when the compressor comes on after the air is depleted to a certain level. Adjust it as needed.
