Baxi Boiler Fan + Sensing Electrode Service Kit 5132366 720011701 5109925

Product Overview

The Baxi Boiler Fan and Sensing Electrode Service Kit (5132366, 720011701 & 5109925) is a replacement service kit designed for use within selected Baxi heating systems.

This kit combines important combustion-related components, including the boiler fan and sensing electrode. The boiler fan provides the required airflow for the combustion process and assists with the safe removal of combustion gases through the flue system. The sensing electrode helps monitor flame detection, allowing the boiler control system to confirm safe burner operation.

A correctly functioning fan and sensing electrode are essential components for reliable ignition, combustion control, and safe boiler operation.

Technical Insight & Common Failure Symptoms

The boiler fan and sensing electrode work together as part of the combustion and safety system. The fan controls airflow into the combustion chamber, while the sensing electrode provides flame feedback to the boiler electronics.

Over time, these components may experience wear, electrical faults, contamination, or performance issues.

Typical symptoms linked to faulty fan or sensing electrode components include:

• Boiler failing to ignite
• Boiler locking out during the ignition sequence
• Fan not starting or making unusual noises
• Intermittent burner operation
• Flame detection faults
• Boiler shutting down shortly after ignition
• Combustion-related fault codes

Replacing worn combustion components may help restore correct ignition, flame detection, and reliable boiler operation.
