What it is
The Baxi 720885501 is a fan wiring harness supplied for the Megaflo 2 System Compact GA range of gas boilers. It carries the low-voltage supply and feedback signals between the combustion fan and the appliance control board, so the fan runs at the speed the PCB demands for the current firing rate. The harness is built as a compact assembly to suit the tight layout inside the Compact GA casing.
Signs this part needs replacing
- The fan fails to start, or runs only intermittently, with the boiler locking out shortly after a demand for heat.
- Fan-related fault codes appear on the appliance display and clear only temporarily after a reset.
- The harness connector or individual conductors show heat damage, brittleness or discolouration.
- The plug does not sit firmly on the fan or PCB terminal, or the wiring has been chafed against the casing.
- Fan speed is erratic, causing poor combustion readings or repeated ignition attempts.
Before you order
- Check the appliance GC number against the compatibility list to confirm the harness suits your model.
- Note the alternative number 1119936 when cross-referencing older documentation or stock records.
- Inspect the fan and PCB terminals at the same time, as a damaged connector can affect a replacement harness.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
