Signs this part needs replacing

  • The bulb no longer sits securely in the holder
  • The holder is cracked, deformed or corroded
  • The bulb works loose in service, causing erratic temperature sensing
  • The boiler cycles or overheats because the bulb is not held in its correct position
  • Visible damage or distortion around the holder body or its seating

Before you order
