Possible Causes
Unplugged or failed Crystal Quest power supply, Tripped GFCI or breaker, Faulty power jack or internal fuse, Defective main control board
How to Fix / Troubleshooting
Safety first: Use caution around electrical outlets. Do not work on live circuits.
- Check outlet: Verify the outlet has power by plugging in another device. Reset any tripped GFCI or breaker.
- Inspect adapter: Confirm the Crystal Quest AC adapter is firmly plugged in and not warm, swollen, or damaged. Replace with an OEM adapter if suspect.
- Check power jack: Wiggle the power plug at the valve. If the display flickers, the jack or board is loose or damaged and the Crystal Quest main control board may need replacement.
- Board replacement: If a known-good adapter and outlet do not power the unit, replace the main control board following Crystal Quest service procedures.
