What it is

The Potterton 665964 is an ignition and ionisation unit for Potterton Commercial gas boilers. It forms part of the pilot assembly, providing both the ignition spark and the flame ionisation signal that proves the pilot is lit. It is suitable for use with natural gas and LPG.

Signs this part needs replacing

  • Boiler fails to ignite or locks out
  • No flame detection, causing repeated lockouts
  • Pilot will not light or stay lit
  • Intermittent ignition or flame failure during operation
  • Error codes relating to ignition or flame sensing

Before you order

  • Confirm your boiler model and kW rating against the fits list
  • Check fuel type (natural gas or LPG) is compatible
  • Verify the existing part number or visual match
  • Ensure safe isolation of gas and electrical supplies before fitting
