What it is
The Ideal 174865 is a sensor used across Ideal solar thermal and commercial appliance ranges. It monitors temperature inside the unit and passes that reading to the control system, which uses it to regulate operation and keep performance steady. It sits in the thermostats, thermistors and sensors group of Ideal spare parts and is a serviceable item, replaced when its readings stop tracking the actual system temperature.
Signs this part needs replacing
- Temperature readings that drift away from the actual system or cylinder temperature
- The appliance cycling on and off more frequently than normal
- Lockouts or fault codes linked to temperature sensing
- Hot water or collector temperature that no longer matches the set point
- Intermittent running as the sensor or its connection degrades
Before you order
- Check the appliance model and serial number against the compatibility list before ordering.
- Confirm the number on the existing sensor; 1780382 is also used to identify this part.
- Inspect any seal or gasket at the sensor pocket and renew it if it is worn or hardened.
