Glowworm Betacom2 24 28 Boiler Main PCB 0020118138

Product Overview

The Glowworm Boiler Main Printed Circuit Board (Part Number: 0020118138) is an electronic control component designed for Glowworm Betacom2 24 and 28 combination boilers manufactured from 2012.

The PCB forms part of the boiler's central electronic control system, processing electrical signals from connected sensors, switches and other components to coordinate appliance operation.

It supports essential boiler functions, including ignition sequencing, burner control, temperature monitoring and the response to central heating and domestic hot water demand.

Correct PCB operation is important for normal boiler functionality and the operation of its electronic 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 main PCB acts as the boiler's central electronic controller, receiving information from connected components and coordinating the appliance's operating sequences.

Electrical faults, damaged connections, moisture exposure or deterioration of electronic components may interfere with normal PCB operation.

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

• Boiler failing to start or operate correctly.

• Intermittent boiler operation.

• Boiler failing to respond to central heating demand.

• Boiler failing to respond correctly to domestic hot water demand.

• Boiler failing to complete its normal ignition sequence.

• Unexpected boiler shutdowns or safety lockouts.

• Irregular operation of connected electrical components.

• Visible damage or deterioration affecting the circuit board.

These symptoms do not necessarily confirm a faulty PCB, as similar problems may result from wiring, sensors, ignition components, the user interface PCB or other boiler controls. Correct professional diagnosis should be carried out before replacing the board.

Safety Advice

Boiler printed circuit boards are safety-related electronic components. 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 that the correct PCB is installed and all electrical connections are securely fitted.

Any required PCB configuration and appropriate electrical safety, ignition, flame supervision and operational checks must be completed before returning the boiler to service.
