Maintenance Tips

• Protect from moisture & corrosion: Ensure the control panel housing is sealed—water intrusion is a leading cause of board failure in heat pump systems.
• Check power supply stability: Verify proper voltage and breaker sizing to avoid electrical surges that can damage the PCB.
• Inspect wiring connections regularly: Loose or corroded wires can cause faults, display issues, or intermittent operation.
• Keep control compartment clean: Remove dust, insects, and debris that may short circuits or block airflow.
• Monitor error codes & display behavior: Address faults early—this board manages key heater functions and diagnostics.
• Avoid DIY handling of electronics: Static discharge or improper handling can damage sensitive components—use qualified technicians.
• Check transformer & fuse condition: Many “no display” issues stem from supporting components, not just the board itself.
