Troubleshooting tips for your TNT air compressor when it won't start

Check the electrical outlet for power. Reset the house circuit breaker if the electrical outlet is dead. If the electrical outlet works, shut off the air compressor and bleed all the air from the tank. Flip the pressure switch control lever to the Auto position.

If the pump starts when the tank is empty, then the check valve may be stuck open. The check valve prevents tank air from back flowing to the pump. A stuck-open check valve causes high pump head pressure, preventing the compressor from restarting. Test the check valve by allowing the compressor to fill the tank until the pump shuts off. Then pull the ring on the safety valve to bleed air out of the tank to reach the cut-in pressure, so the pressure switch attempts to restart the motor to refill the air tank. If the compressor won't start with air in tank, replace the check valve.

If the compressor won't start with an empty air tank, replace the pressure switch if it isn't activating the pump motor. Replace the pump motor if it doesn’t start when activated by the pressure switch.

TNT air compressor safety tips

• Always wear a safety mask or respirator when using air tools or compressed air for cleaning.
• Work in a clean, dry, well-ventilated area.
• Never directly inhale compressed air. It isn't suitable for breathing.
• Don't leave air tools unattended with the air hose attached.
• Don't use inflator nozzles for dusting and cleaning.
• Check conditions of hoses and fasteners before each use. Replace the air hose if damaged. Tighten any loose fasteners before using the air compressor.
