Question and Answers


Why does the air compressor only come on when the relay clicks?


The click you are hearing is the motor protector closing inside the motor. Something is causing your motor to draw excessive amperage and tripping the motor protector.

If you are using an extension cord, it might not be heavy enough. The power from the house wiring might not be strong enough to run the compressor. The motor might have an internal problem causing the protector to trip.

Someone needs to check the voltage to the compressor and see if the voltage drops below 110 when the motor tries to start.
