Why won't my Graco Magnum True Airless Project Painter Plus motor run?

If the Graco Paint Sprayer motor isn't running, first ensure the pressure control isn't set at zero; turn the pressure control knob clockwise to increase the pressure setting. Also, verify the electric outlet is providing power by testing it with a known working device and reset the circuit breaker or replace the fuse if needed. Check the sprayer and any extension cords for damage, replacing them if necessary. Lastly, a seized pump could be the culprit, especially if paint has hardened or water has frozen inside. If frozen, thaw completely before use. If paint has hardened, and removing the pump doesn't allow the motor to turn, consult an authorized service center.
