Why does my Graco Industrial Equipment have no hose heat or low hose heat?
- W
  Whitney RiceNov 24, 2025
  Several factors can cause low or no hose heat: * Loose electrical connections: Check and repair hose electrical connections. * Tripped circuit breakers: Reset breakers CB1 or CB2. * Hose zone: Ensure the hose zone is turned on by pressing the zone key. * Temperature settings: Verify A and B temperature setpoints and the hose temperature setpoint are appropriately set and increase if needed. * Temperature control board: Check if the board LED is blinking; if not, check power connections. If the board has power but the LED isn't blinking, replace the board. * Flow rate: Use a smaller mix chamber or decrease pressure if the flow is too high. * FTS installation: Install the FTS if it is not installed. * Heat-up time: Allow sufficient time for the hose to heat up, or preheat th...

What causes erratic display on Graco Industrial Equipment; display turns on and off?
- J
  John PowellAug 27, 2025
  An erratic display that turns on and off may be due to: * Low voltage: Ensure the input voltage is within specifications. * Poor display connection: Check cable connections and replace any damaged cables. * Damaged display cable: Clean corroded connections or replace the cable if damaged. * Ungrounded display cable: Ground the cable. * Excessively long display extension cable: Ensure the cable does not exceed 100 ft (30.5 m).

Why is my Graco Industrial Equipment hose temperature exceeding the set point?
- H
  hallmichaelAug 27, 2025
  If the hose temperature exceeds the set point, consider these causes: * Overheating heaters: Check primary heaters for thermocouple problems or a failed element. * Faulty thermocouple connections: Ensure FTS connections are snug and clean. Also, check the connections of thermocouples to the long green plug on the heater control board, cleaning off any debris and re-plugging the wires and connector. * Damaged insulation: Ensure the hose bundle has adequate insulation evenly covering the entire length and connection joints.

What to do if there is no pressure on one side of Graco Industrial Equipment?
- J
  Jacob JohnsonSep 23, 2025
  If there is no pressure on one side, check if fluid is leaking from the heater inlet rupture disk (314). If so, check if the heater (2) and PRESSURE RELIEF/SPRAY valve (SA or SB) are plugged; clear them if necessary. Replace the rupture disk (314) with a new one, and do not replace it with a pipe plug.

What to do if temperature display does not illuminate on Graco Industrial Equipment?
- Z
  Zachary WeaverSep 18, 2025
  If the temperature display does not illuminate: * Check cable connections. * Clean corroded connections or replace the cable if damaged. * Swap the display connection to the motor control board with the connection to the heater control board to see if the heater control board is causing the problem. Otherwise, the display cable or display is failing.

What causes low pump output in Graco Industrial Equipment?
- D
  David WardSep 5, 2025
  Low pump output can be attributed to: * Obstructions: Clear any obstructions in the fluid hose or gun, and use a hose with a larger ID. * Pump valves: Consult the pump manual regarding worn piston or intake valves in the displacement pump. * Pressure setpoint: Reduce the pressure setpoint to increase output.
