What it is
The NTC tank/external sensor wiring is a Potterton Commercial thermistor lead used to connect the tank or external NTC sensor to the boiler's control circuit. It carries the sensor signal so the boiler can read stored water or external temperatures and regulate firing accordingly. This item is listed under gas boiler spares for the Potterton Commercial Sirius range.
Signs this part needs replacing
- Temperature readings from the tank or external sensor are erratic, fixed or clearly wrong
- The boiler fails to respond to changes in stored water or external temperature
- Intermittent lockouts or shutdowns traced to a lost or unstable sensor signal
- Visible damage to the lead, such as cracked insulation, crushed cable or a corroded or loose plug
- Open or short circuit across the lead when tested
Before you order
- Confirm the appliance model against the fit list above before ordering
- Check the part number on the existing lead or the appliance documentation matches 5141496
- Inspect the sensor connector type and routing on the appliance to confirm the lead is the correct item for the installation
- If the sensor itself is also suspect, identify whether the sensor or the wiring is at fault before replacing
