What it is
The Hamworthy thermocouple with special high temperature rating, part number 533901220, is a flame-sensing safety component for Hamworthy UR series floor standing boilers. It is used in permanent pilot (P/Pilot) assemblies to detect the pilot flame and maintain the gas valve during operation. The high temperature rating suits pilot locations where standard thermocouples may be affected by heat.
Signs this part needs replacing
- Pilot flame lights but goes out when the control knob is released.
- Boiler fires briefly then shuts down because the pilot flame is not proving.
- Repeated lockouts or loss of flame signal during operation.
- The pilot requires the button to be held for an unusually long time before the burner stays lit.
Before you order
- Confirm your appliance model is listed in the Fits section.
- Check the existing thermocouple connection and pilot assembly arrangement.
- Verify part number 533901220 against the manufacturer's parts list.
- Ensure the pilot assembly uses a permanent pilot (P/Pilot) configuration.
