What it is

Siemens LMU64 main PCB control box manufactured for Hamworthy. It is configured for the Purwell Variheat PV65HE natural gas floor standing boiler and controls ignition, sequencing and safety functions. This PCB is model-specific, so the exact boiler model must be identified before ordering.

Signs this part needs replacing

  • Boiler fails to fire or does not respond to a call for heat
  • Repeated lockouts or error codes on the boiler display
  • No display, no power to the control panel, or unresponsive controls
  • Fan, pump or ignition sequence not starting
  • Intermittent operation or unexpected shutdowns

Before you order

  • Confirm the exact boiler model is the Purwell Variheat PV65HE
  • Confirm the boiler is the natural gas (NG) version
  • Check the existing PCB markings match Siemens LMU64 and part number 533901517
  • PCB is model-specific; a different configuration will not be suitable
