To Next PageTo Next PageWhat to do if the fan is not working on my Graco Reactor A-25 Paint Sprayer?
If the fan isn't working, it could be due to a blown fuse, so replace it. Also, check for any loose wires. If neither of those is the issue, the fan itself may be defective and need replacement.
What causes a fluid leak in the pump packing nut area of my Graco Reactor A-25 Paint Sprayer?
A fluid leak in the pump packing nut area is likely caused by worn throat seals, so replace them.
What to do if Graco Reactor A-25 Paint Sprayer display does not illuminate?
If the display doesn't illuminate, check if the power cord is plugged in and the disconnect switch is ON. Also, ensure the input voltage is within specifications and check all wire and cable connections.
Why is fluid pressure low or dropping in my Graco Reactor A-25 Paint Sprayer?
Low or dropping fluid pressure can be caused by several factors. Ensure the air supply pressure is adequate when spraying. It might be necessary to increase air compressor size to meet flow requirements. Also, remove any airline quick disconnects and use a 3/8 in. (0.95 cm) ID or larger air supply hose (or 1/2 in. (12.7 mm) if longer than 25 ft (7.6 m)). Finally, check for icing in air motor exhausts or mufflers.
Why are the display buttons not working properly on my Graco Reactor A-25 Paint Sprayer, and I cannot exit an operation?
If the display buttons aren't working correctly and you can't exit an operation, it could be due to a broken membrane switch, so replace it. Another possibility is a disconnected or broken ribbon cable, so connect or replace the cable.
What does it mean if the hose display reads 0A on startup for my Graco Paint Sprayer?
If the hose display reads 0A on startup, it indicates that the FTS is not installed and the zone is off. Install the FTS, or adjust the current to the desired setting.
How to troubleshoot no hose heat in my Graco Reactor A-25?
If there's no hose heat, start by checking the hose electrical connections for any looseness and repair if necessary. Make sure the circuit breakers (CB1 or CB2) haven't tripped and reset them if needed. Verify that the hose zone is turned on by pressing the zone key. Also, check if the A and B temperature setpoints are too low and increase them if necessary. A failed temperature control board could also be the problem. To check the temperature control board, open the cabinet and see if the board LED is blinking. If not, check the power wiring connections to ensure the board has power. If the board has power and the LED is not blinking, replace the board.
What causes low heat in A or B zones of my Graco Paint Sprayer?
Low heat in zones A or B can stem from various causes. First, check if the A and B temperature setpoints are too low and increase them if needed. High flow can also be a factor, so consider using a smaller mix chamber or decreasing the pressure. Other potential issues include a defective heater, loose connectors or wire nuts, low voltage, an overheated temperature control board (check fan operation, ensure the door is closed, and verify cooling holes are clear), or fluid that is too cold (preheat the fluid).
What to do if Graco Paint Sprayer heat zones do not operate?
If the heat zones aren't working, first, connect the power cord. Then, turn the Main Disconnect Switch ON. Finally, check the power cord connections to ensure they are properly connected.
What to do if the circuit breaker trips on my Graco Reactor A-25 Paint Sprayer?
If the external main supply power circuit breaker trips and the Reactor disconnect switch fails when switched on for your Graco Paint Sprayer, it could be because the power terminal jumper was left in the 200-240V, 1 phase position while using 200-240V, 3 phase or 350-415V, 3 phase power. To fix this, place the jumpers in the correct position. Also, replace the main power disconnect switch.
