What it is
The Hamworthy S70C main control PCB is the primary control board for Hamworthy Sherbourne wall hung gas boilers. It governs ignition, flame supervision and boiler sequencing. The board is configured for natural gas; where LPG is used, the PCB requires a program change that must be specified at the point of order.
Signs this part needs replacing
- Boiler fails to ignite or locks out repeatedly with no other fault identified
- Blank or unresponsive control panel display
- Erratic operation, such as random lockouts or the fan and pump running without a demand
- Burner fails to modulate, or the boiler cycles abnormally
- Visible scorching, burnt tracks or other physical damage on the board
Before you order
- Confirm the appliance is a Hamworthy Sherbourne S65 or S70 wall hung boiler.
- Check the existing board's part number and model marking against 533901381 and S70C.
- Confirm whether the installation is natural gas or LPG; LPG requires a program change that must be specified on order.
- Isolate the boiler from the electrical supply before fitting.
