Compatibility and Buyer Check
Before ordering, confirm that your system manual or existing board label calls for GLX-PCB-DSP. This part should be matched by part number, display layout, connector position, board style, and system compatibility, not by image alone.
If the display board is not the only suspected issue, compare the Hayward GLX-PCB-RITE main circuit board before replacing more parts. For Aqua Rite Pro display-face or button issues, review the Hayward GLX-AR-PRO-MEM display membrane switch assembly instead of this standard Aqua Rite PCB display.
If your AquaTrol control unit is damaged beyond the display board, compare the Hayward GLX-CTL-TR-HP-T HP twist lock control unit or Hayward GLX-CTL-TR-RJ RJ straight blade control unit based on plug style and model.
What This PCB Display Does
The PCB display is the user-facing display board inside compatible Hayward salt chlorine generator controls. It helps show system readings, settings, and control information so the unit can be monitored during normal operation.
Replacing the display board may help when the screen is blank, faded, cracked, unreadable, or not responding as expected. It will not fix every salt system issue. No power, low chlorine output, incorrect salt readings, flow warnings, or cell errors may also come from the main PCB, transformer, fuse area, flow switch, salt cell, wiring, or water chemistry.
Before You Order
Check these details before purchasing:
- Confirm the exact part number GLX-PCB-DSP.
- Verify that your Hayward system uses this Aqua Rite PCB display style.
- Compare the board shape, LCD display position, connector points, and knob layout with your existing part.
- Inspect the control box for moisture, corrosion, burned marks, or loose wiring.
- Confirm whether the issue is the display board, main PCB, transformer, fuse, wiring, salt cell, or flow switch.
- If the unit has no power or intermittent power, check the Hayward GLX-XFMR transformer replacement before assuming the display board has failed.
- Do not install this part in an Aqua Rite Pro, OnCommand, or non-compatible system unless the service manual confirms fitment.
Installation and Safety Notes
Turn off power at the breaker before opening the control box or touching the display board. Do not work on pool electrical equipment while the system is powered.
Before removing the old PCB display, take clear photos of the wiring, connector locations, board orientation, and mounting position. Install the replacement in the same position as the original board. Do not force connectors, bend pins, or reuse damaged wiring.
After installation, close the control box properly, restore power, and confirm that the display, buttons or knob, system readings, and connected salt system functions are working normally.
Maintenance and Troubleshooting Tips
To help protect the replacement display board:
- Keep the control box closed and protected from moisture.
- Inspect wiring and connectors during routine service.
- Do not press or adjust controls with excessive force.
- Check transformer, fuse, main PCB, and wiring issues if the display problem returns.
- Keep the salt cell clean and water chemistry balanced to reduce system strain.
- Follow Hayward service instructions for diagnostics and startup after replacement.
