How to Fix / Troubleshooting
Safety first: Turn OFF power and gas. Do not attempt to repair the PCB at component level.
Steps to check and correct:
- Inspect PCB area: Remove the front cover and look for signs of water leaks, corrosion, or burnt components on the PCB. Address any leaks before replacing the board.
- Check all connectors: Reseat all harness connectors to the PCB to rule out poor contact.
- Power reset: Turn off power at the breaker for 5–10 minutes, then restore.
- Professional replacement: If error 67 remains, the PCB must be replaced with an OEM Noritz board by a qualified technician. Ensure correct model-specific board is used.
