What it is
This is a Worcester Bosch transformer, supplied under part number 7101640. It is the component that steps mains voltage down to the low voltage used by the boiler's control electronics, so the printed circuit board and connected sensors receive a stable supply. It is used across the Buderus and Worcester GB162 range and the Buderus 600-28C.
Signs this part needs replacing
- Boiler has no display or the control panel stays completely dead with mains present
- Boiler fails to fire and the PCB shows no activity despite a live supply
- Repeated fuse failure on the low-voltage side of the control circuit
- Intermittent shutdowns or erratic control behaviour that clears when the board is disturbed
- Visible overheating, discolouration or a burnt smell around the transformer windings
Before you order
- Check the GC number and appliance serial plate to confirm the boiler model before ordering
- Compare the numbers on the existing transformer against the alternative numbers listed below
- Confirm whether any mounting hardware or seal from the original assembly is being reused
- This is not a gas-carrying component, but work inside the appliance casing should be carried out by a competent person
