How does the LCD interface improve troubleshooting?

The built-in 2-line by 16-character LCD delivers plain-text messages and numeric values so you can read temperature, status, and error codes at a glance. Clear diagnostics reduce time spent guessing and limit unnecessary part swaps during service calls.

• Shows real-time temperature and operating state

What problems can replacing the PCB resolve?

Installing the NEWNUVAIP 013464F often cures control and display-related symptoms that impair heater performance. It addresses both user-interface failures and control logic issues that produce inconsistent heating or frequent fault conditions.

• Blank or unreadable LCD screens and missing temperature readouts
• Inaccurate or unstable temperature control and cycling
• Unresponsive front-panel buttons or failure to start
• Persistent, unclear, or frequent error codes caused by board faults

How do I confirm compatibility before ordering?

Verify compatibility by checking your heater’s model number and control board part label. Compare the listed models and production dates with your unit, and inspect your current board’s connector layout and LCD type to ensure a correct replacement.

• Confirm your heater’s exact model (sticker on the unit) and production year
• Compare connector positions and mounting holes to the OEM board
• Ensure your existing board uses a 2-line, 16-character LCD interface
• Contact a certified technician if you’re unsure about fitment or wiring

Who is this replacement board for? The NEWNUVAIP 013464F is intended for pool and spa owners, service technicians, and facility maintenance teams working with Raypak digital gas heaters that match the listed model numbers. If your unit suffers from display failures, erratic temperature control, or unresponsive controls and you want a like-for-like PCB swap, this board provides a practical, plug-and-play repair option. Always power down and follow safety procedures or consult a professional installer when replacing control electronics.
