Vaillant VC 112 142 182 242 282 Boiler Fan Module PCB 130451

Product Overview

The Vaillant Boiler Fan Module PCB (Part Number: 130451) is an electronic fan-control component designed for selected Vaillant Thermocompact and Combicompact boilers.

The circuit board forms part of the boiler's electrical control system, supporting the operation and monitoring of the fan and associated combustion airflow controls.

It works alongside other boiler control components to support the required operating conditions during the ignition and combustion sequences.

Correct operation of the fan-control PCB is important for reliable boiler functionality and the operation of its associated safety controls.

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 PCBs should be professionally inspected and tested to confirm correct operation before installation.

Technical Insight & Common Failure Symptoms

The fan module PCB is a specialised electronic control board associated with the boiler's fan and combustion airflow system.

Electrical faults, damaged connections, moisture exposure or deterioration of electronic components may interfere with the fan-control circuit and associated boiler operating sequences.

Possible symptoms that may indicate a fan-control PCB or associated electrical problem include:

• Boiler fan failing to start or operate correctly.

• Intermittent fan operation.

• Boiler failing to complete its normal ignition sequence.

• Burner failing to ignite when the required airflow conditions are not established.

• Boiler failing to respond correctly to heating demand.

• Unexpected boiler shutdowns or safety lockouts.

• Irregular operation of the fan-control circuit.

• Visible damage or deterioration affecting the circuit board.

These symptoms do not necessarily confirm a faulty fan module PCB, as similar problems may result from the fan motor, wiring, air pressure switch, other electronic controls or restrictions within the combustion and flue system. Correct professional diagnosis should be carried out before replacing the board.

Safety Advice

Boiler fan-control PCBs are safety-related electrical components within gas-fired appliances. Inspection, removal and installation must only be carried out by a Gas Safe registered engineer who is suitably qualified for the appliance and work being undertaken.

Always isolate the appliance's electrical supply before carrying out any work and follow the manufacturer's installation and servicing instructions. Ensure the correct circuit board is installed and all electrical connections are securely fitted.

Appropriate electrical safety, fan operation, airflow monitoring, ignition and combustion safety checks must be completed before returning the boiler to service.
