What it is

The FLOW CONTROLLER (20 SECTION)- FLUE is a Potterton flow controller supplied under part number 5141236. It is a flow switch component used on Potterton Commercial NXR5I boiler assemblies, where it monitors water flow through the appliance and provides the signal that permits burner operation. The part is specified for the 20 section build of the NXR5I range.

Signs this part needs replacing

  • The boiler runs the pump but the burner fails to fire on a call for heat.
  • Repeated lockouts that clear on reset and then recur during operation.
  • Intermittent or lost flow signal at the control, causing the appliance to shut down mid-cycle.
  • Circulation is present at the pipework but the boiler does not register flow.

Before you order

  • Confirm the appliance model and section count match the fit list above, as the controller is specified by section rating.
  • Check the existing part number 5141236 against the component being removed.
  • Verify that flow, not temperature or pressure, is the reported fault before replacing the controller.
  • Inspect the surrounding pipework and connections for debris or restriction that could affect flow sensing.
