What to do if my Graco Tradeworks 170 Paint Sprayer is plugged in but the motor won't run?

If your Graco Paint Sprayer's power switch is on, and it's plugged in, but the motor doesn't run, and the pump doesn't cycle, here are a few things to check: * Ensure the pressure isn't set to zero; turn the pressure control knob clockwise to increase the pressure setting. * Try a different electrical outlet, or test the outlet with a known working device. Also, reset the building circuit breaker or replace the fuse. * Inspect the extension cord and sprayer electric cord for damage, replacing them if necessary. * If paint or water is frozen or hardened in the pump, unplug the sprayer and allow it to thaw completely in a warm area before attempting to restart it. If the paint is hardened, the pump packings, valves, drivetrain, or pressure switch may need replacement.
