What it is

The Potterton 5132575 is the wiring harness for the heating NTC sensor and pump (flow) circuit on Potterton Commercial boilers. It carries the sensor and pump connections to the boiler control, so the flow temperature can be read and the pump switched correctly. NTC sensors change resistance with temperature, which makes the integrity of this wiring run critical to accurate flow temperature measurement.

Signs this part needs replacing

  • Flow temperature readings that are erratic, implausible or inconsistent with the boiler's actual operation
  • Sensor or flow-related fault codes appearing at the boiler control
  • Lockouts or overheat trips linked to incorrect flow temperature sensing
  • Heat damage, brittleness or chafing on the harness insulation
  • Corroded, loose or intermittent connector terminals at the sensor or pump end

Before you order

  • Confirm the appliance model and variant against the boiler's wiring diagram before ordering
  • Check whether the fault lies in the wiring or in the NTC sensor or pump itself
  • Inspect the existing harness connectors for corrosion, heat damage or loose pins
  • Verify the part number 5132575 matches the number shown on the component being replaced
