Why does my Graco 17N162 make no sound when I pull the trigger?
- Mmolly74Sep 9, 2025
If your Graco Paint Sprayer makes no sound when you pull the trigger, it could be due to several reasons: * The diagnostic light doesn't blink upon plugging in, indicating no power. Verify the power supply to the sprayer. * If the diagnostic light blinks once, wait 20–30 minutes for the motor to cool down. * If the diagnostic light blinks four times when the trigger is pulled, it indicates a locked rotor. In this case, the pump and/or motor assembly may need replacement. * The Smartcontrol may need replacement, or the motor itself may need to be replaced.
