Product Overview

The Myson Boiler Fan Assembly 402A1233 (4520645) is a combustion fan assembly designed for use within selected Myson heating systems.

The boiler fan is an important component of the combustion system. It provides the required airflow to support the combustion process and assists with the safe removal of combustion gases through the flue system during boiler operation.

The fan works together with the boiler control system and safety devices to help ensure the appliance operates correctly. If the fan does not operate within the required parameters, the boiler safety system may prevent normal ignition to support safe operation.

Technical Insight & Common Failure Symptoms

The boiler fan controls airflow to the combustion chamber and supports the correct operation of the combustion process. During normal operation, the fan must run correctly to allow the boiler to complete its ignition sequence and operate safely.

Over time, mechanical wear, electrical faults, debris, or internal component failure may affect fan performance.

Typical symptoms linked to a faulty boiler fan include:

• Boiler failing to ignite or complete the ignition sequence
• Fan making unusual noises or excessive vibration during operation
• Boiler locking out due to airflow or combustion-related faults
• Fan failing to start when heating or hot water is requested
• Reduced boiler performance caused by incorrect airflow
• Intermittent boiler operation or shutdowns

Replacing a faulty boiler fan may help restore correct airflow and support reliable boiler operation.
