What it is
The Baxi 720848601 is a printed circuit board (PCB) supplied for the RDS System 28 LPG appliance range. It is the control board that runs the appliance's operating sequence, handling ignition timing, fan and pump control, temperature sensing inputs and fault code output to the display or diagnostic interface. The board is listed by Baxi under part type PCB and carries the alternative number 1110869.
Signs this part needs replacing
- The appliance fails to fire or runs through the start sequence without igniting
- Repeated lockouts or fault codes that clear and then return after a reset
- No response from the controls, or a blank or unlit display
- Heating and hot water behave erratically, with the pump or fan not starting on demand
- Visible damage on the board itself, such as scorching, a blown track or swollen capacitors
Before you order
- Confirm the GC number and model on the appliance data badge against the compatibility list before ordering
- Check the existing board's part number and any alternative number printed on the PCB label
- Inspect the board connector plugs and harness for corrosion or heat damage, as these can mimic a board fault
