Why is there low hose heat in my Graco 246029 Paint Sprayer?
- GGeorge DavisSep 8, 2025
If your Graco Paint Sprayer has low hose heat, increase the A and B setpoints, as the hose is designed to maintain temperature, not increase it. Check and increase the hose temperature setpoint if necessary to maintain heat. High flow can also cause this; use a smaller mix chamber or decrease the pressure. If the current is low and FTS is not installed, install FTS. Also, ensure the hose heat zone has been on long enough to allow the hose to heat up, or preheat the fluid. Finally, check for loose hose electrical connections and repair as necessary.
