Using It on the Job

1. Before starting any work, always isolate power to the heater at the main switchboard and confirm zero voltage with a calibrated multimeter.
2. Access the heater's control compartment and carefully locate the existing control board.
3. Photograph all wiring connections for reference before disconnecting any harnesses or sensors from the old board.
4. Remove any mounting screws or clips holding the old board in place and carefully extract it.
5. Install the new SY651972 board, ensuring it is correctly seated and all wiring harnesses are reconnected firmly and accurately.
6. Restore power and test the heater's operation through all modes (heat, fan only) to confirm proper function.

Limitations & Safety Notes

• Installation and servicing of gas appliances must be performed by a fully qualified and licensed gas fitter or HVAC technician.
• Always ensure electrical power is isolated and locked out before commencing any work on the heater.
• This board is specifically for Braemar TQ, TQD, and SSQ series models; confirm compatibility before installation.
• Follow all relevant Australian standards and Safe Work guidance during installation and testing.

When swapping out these control boards, always take a clear photo of the existing wiring setup before disconnecting anything. It's a quick habit that saves you a heap of headaches, especially when you're piecing it back together in a tight spot.

Pair With

Consider pairing this control board with a new ignitor or flame sensor for a complete heater overhaul. A quality digital multimeter is also essential for diagnostics and safety checks.
