What it is

The FLOW CONTROLLER (18 SECTION)- FLUE is a Potterton Commercial flow controller supplied as a boiler spare for the Potterton Commercial NXR5i range. It is listed under the flow switch category and is fitted in the flue section of the appliance. Its role is to sense flow through the flue path and signal the boiler control to allow or prevent operation.

Signs this part needs replacing

  • Boiler locks out or fails to fire despite a proven demand for heat
  • Intermittent operation that clears when the flue flow path is disturbed
  • Fault code or diagnostic indication relating to flue flow or air pressure
  • Boiler running only when the flue is at a particular temperature or load
  • Visible damage, contamination or sticking at the controller

Before you order

  • Confirm the appliance model and section count match the fitment list
  • Check the existing controller against part number 5141234
  • Verify that the fault is traced to the flue flow controller and not to the flue itself
  • Confirm the appliance is isolated and safe to work on before removal
