Things to consider.

• Is the tank full of air so it doesn't think its supposed to kick on?
• Is there a "reset" button on the motor that is tripped?
• Is the Regulator adjustment being done correctly?
• Is it plugged in to a proven working power source?
• Is there is "not" enough restriction to the air flow that the gauge won't move up?
• With the Regulator turned all the way off, does the compressor build up pressure then shut off?
• When you open the tank drain slightly does the compressor kick on at about 90~100psi using the Tanks gauge to measure?
