Why does my Graco Industrial Equipment hose not maintain temperature while spraying?
- C
  cjohnstonSep 9, 2025
  If the hose temperature isn't maintained during spraying, consider: * Setpoint adjustment: Increase A and B setpoints, as the hose is designed to maintain, not increase, temperature. * Ambient temperature: If it's too cold, increase A and B setpoints. * Flow rate: Use a smaller mix chamber or decrease pressure if the flow is too high. * Preheating: Ensure the hose is fully preheated before spraying. * Voltage: Verify the line voltage, as low voltage reduces power to the hose heat system.

  Thomas ParkerAug 23, 2025
  If the motor isn't working, consider these potential causes: * Loose connections: Check the connections at the motor control board. * Circuit breaker: Reset the breaker (CB5) and check the voltage output. * Worn brushes: Inspect the brushes and replace if shorter than 0.7 in (17 mm). * Brush springs: Realign or replace broken or misaligned brush springs. * Brush holder: Clean the brush holder if brushes or springs are binding. * Armature: Replace the motor if the armature is shorted. * Motor commutator: Have the motor commutator resurfaced if damaged. * Motor control board: Replace the board if it's damaged.

What causes erratic display on Graco Industrial Equipment; display turns on and off?
- J
  jessicapotterAug 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?
- R
  Rebecca MahoneyAug 28, 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?
- R
  rriosSep 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?
- L
  luisdavenportSep 17, 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 to do if Graco Industrial Equipment primary heater(s) does not heat?
- E
  Eric HowellSep 7, 2025
  If the primary heater(s) do not heat, check the following: * Heat turned off: Press the A or B zone keys to turn the heat on. * Temperature control alarm: Check the temperature display for a diagnostic code. * Thermocouple signal failure: Check for a disconnected Fluid Temperature Sensor (FTS) or thermocouple.

What causes low pump output in Graco Industrial Equipment?
- D
  Dr. Melissa WoodardSep 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.
