What to do if my Graco Paint Sprayer motor won’t operate?
- CCassandra FernandezAug 7, 2025
If your Graco Paint Sprayer motor won’t operate, try the following: First, slowly increase the pressure setting. If that doesn't work, the spray tip or fluid filter may be clogged, so relieve the pressure and clear the clog or clean the gun filter. If water or water-based paint has frozen in the sprayer, thaw it completely in a warm area before starting. If paint has hardened, replace the pump packings. Also, check the displacement pump connecting rod pin and ensure it is in place and secured with the spring retainer. If the fan still won’t turn, replace the motor.
