What it is
The Potterton 10/18761 is a thermistor used to sense domestic hot water and central heating water temperature on compatible Potterton gas boilers. It reports water temperature back to the boiler's control system so that firing and modulation can be managed correctly. This sensor supersedes earlier code 43001101.
Signs this part needs replacing
- Boiler displays a temperature-related fault code or lockout
- Domestic hot water runs hot and cold instead of holding a steady temperature
- Central heating flow temperature reads incorrectly or erratically on the display
- Boiler short-cycles or fails to modulate as expected
- Sensor readings drift from the actual measured pipe temperature
Before you order
- Confirm your boiler model against the fitment list above
- Check the existing sensor's part number and connector type before removal
- Inspect the sensor wiring and plug for damage or corrosion
- Isolate the appliance and follow the manufacturer's procedure for sensor replacement
