What it is

The Gledhill GT309 is a flame sensing electrode for Gledhill Gulfstream A-Class boilers. It sits in the combustion path and returns a flame signal to the boiler control, allowing the appliance to confirm that ignition has taken place and to shut down safely if the flame is lost.

Signs this part needs replacing

  • Boiler locks out shortly after ignition or fails to prove flame
  • Repeated ignition attempts, with the burner lighting and then extinguishing
  • Intermittent lockouts that clear on reset but return
  • Flame failure fault codes logged by the boiler control
  • Visible damage, contamination or corrosion on the electrode probe or its lead

Before you order

  • Confirm the appliance is a Gledhill Gulfstream A-Class
  • Check the existing electrode part number against GT309
  • Isolate the electrical supply and gas before fitting
  • Inspect the electrode lead and connection point for damage
