Ideal Mini C24 C28 C32 Boiler Temperature Sensor Thermistor 172496

Product Overview

The Ideal Mini Boiler Temperature Sensor Thermistor (Part Number: 172496) is a replacement temperature-sensing component designed for selected Ideal heating systems.

Part number 172496 is identified as a Temperature Sensor (BI1001 117), forming part of the boiler's temperature monitoring and control system.

The thermistor detects changes in water temperature through variations in electrical resistance, allowing the boiler's electronic control system to monitor temperature and regulate appliance operation.

Accurate temperature sensing is important for reliable heating and domestic hot water temperature control.

ℹ️ Product Condition Options:

This part may be available in New or Refurbished condition. Please select your desired option from the dropdown menu above. Refurbished parts should be professionally tested to confirm correct operation before installation.

Technical Insight & Common Failure Symptoms

The thermistor is a temperature-sensitive electrical component whose resistance changes as temperature varies. The boiler's Printed Circuit Board (PCB) uses this resistance information to monitor water temperature and control the appliance's operation.

A faulty thermistor or associated electrical connection may provide incorrect temperature information, affecting heating or hot water performance.

Possible symptoms that may indicate a thermistor or associated component problem include:

• Boiler failing to maintain the required water temperature.

• Incorrect or inconsistent temperature readings.

• Intermittent boiler operation.

• Boiler failing to respond correctly to temperature changes.

• Unexpected boiler shutdowns or lockouts.

• Temperature sensor-related fault indications.

• Heating or hot water performance affected by incorrect temperature feedback.

These symptoms do not necessarily confirm a faulty thermistor, as similar problems may result from wiring, electrical connections, circulation issues or other boiler components. Correct professional diagnosis should be carried out before replacement.

Compatibility

This part (MPN: 172496, Additional Reference: BI1001 117) is identified for selected Ideal Mini C24, C28 and C32 boiler systems.

Please verify the boiler model, original part number and sensor specifications against the manufacturer's technical documentation before ordering to ensure correct fitment.

Safety Advice

Boiler temperature sensors and associated electrical components should only be diagnosed, removed or installed by a suitably qualified and competent heating engineer.

Always isolate the appliance's electrical supply and allow the heating system to cool before carrying out any work. Where removal of the sensor involves opening the hydraulic circuit, the system must be safely isolated and depressurised. Follow the manufacturer's servicing instructions and complete all required electrical, leakage and operational safety checks before returning the boiler to service.
