What it is

The Baxi 5134158 is a sensor lead for the supplementary burner on Baxi gas boilers. It carries the sensor signal from the supplementary burner to the boiler's control circuit, allowing the appliance to monitor and manage burner operation. It is listed under burner spares for the Baxi Ecogen range.

Signs this part needs replacing

  • Supplementary burner fails to light or lights intermittently
  • Boiler locks out or reports a flame or ignition fault
  • Burner shuts down shortly after starting
  • Visible damage to the lead, such as cracked insulation, scorching or exposed conductor
  • Loose or corroded connector at the sensor or control end

Before you order

  • Check the appliance data badge to confirm the model and GC number
  • Compare the part number on the existing lead, where it is still legible
  • Check the connector type and lead routing against the failed component before fitting
  • Confirm the fault lies with the lead rather than the sensor or control board
