What it is
The Hamworthy Temperature Sensor Flow and Return is a 10K NTC thermistor used to monitor flow and return water temperatures on Hamworthy floor standing boilers. It is supplied under part number 533901431 and listed as a temperature sensor measuring 6 x 45. The sensor provides the temperature signal the boiler controls use for modulation and temperature regulation.
Signs this part needs replacing
- Boiler locks out or reports a flow or return temperature fault
- Temperature readings from the boiler controls appear inaccurate or unstable
- Erratic modulation or burner behaviour that does not match the actual system temperature
- Open circuit, short circuit or resistance reading that falls outside the expected 10K NTC curve
- Sensor resistance drifting or reading inconsistently when checked against temperature
Before you order
- Confirm the existing sensor is a 10K NTC type before ordering
- Check the probe size and mounting arrangement match the 6 x 45 sensor listed here
- Verify the boiler model against the fit list above
- Check the sensor wiring and plug connections, as a poor connection can mimic a failed sensor
