7. Test: Restore power and test the heater's functions, including ignition, fan operation, and safety cut-outs.

Limitations & Safety Notes

• This transformer is specifically for Braemar gas heating appliances with 240V input and 24V control circuits.
• Installation and servicing of gas appliances must be performed by a licensed professional in Australia.
• Always ensure power is isolated and verified dead before commencing any electrical work.
• Mismatching voltage or current ratings can damage the heater's control board or create a fire hazard.
• Follow all manufacturer's instructions and relevant Australian electrical safety standards during installation.

Tradie Pro Tip

Before you even pull out the multimeter to check the transformer, always give the heater's wall controller a good check. Sometimes a flat battery or a setting error can mimic a control circuit issue, saving you a strip-down. If that's good, then check for 240V AC going into the transformer and 24V AC coming out. No 24V out means it's time for a swap.

Pair With

This transformer pairs well with other Braemar control boards, ignitors, and gas valves if you're undertaking a wider heater repair. Don't forget a good quality multimeter to assist with fault finding.
