Product Description
The Braemar BM 325 & X PCB Circuit Board BSC 3 Star Gas Ducted Heater PN. 628820 is an integral component of the Braemar BM 325 & X gas ducted heating system. It is responsible for managing and controlling the electrical functions that ensure your heater operates safely and efficiently. The PCB (Printed Circuit Board) regulates vital components like the gas valve, blower fan, ignition system, and temperature sensors, allowing the heater to maintain optimal operation.
Key Features and Functions of the PCB:
-
Main Role of the PCB:
- The PCB in the Braemar BM 325 & X is the control hub for the heater, directing the various components in the system. It ensures the ignition sequence is initiated, the gas valve opens at the appropriate time, and the system runs efficiently and safely.
- The board monitors inputs from sensors, such as temperature or airflow, and adjusts the heater's operation to ensure that it reaches the desired temperature and maintains that level.
-
Key Functions:
- Ignition Control: The PCB ensures that the heater ignites properly by controlling the timing of the gas valve opening and the spark from the igniter. Without the PCB, the heater would not be able to light the burner.
- Temperature Regulation: The PCB helps control the fan speed and burner operation to maintain the desired temperature in the room. It makes adjustments as needed to prevent overheating or underheating.
- Safety Monitoring: The PCB is responsible for monitoring the system’s safety parameters. If there’s an issue with the airflow, pressure, or another critical factor, the PCB can shut down the system to prevent damage or hazards, such as a gas leak or overheating.
- Error Detection: The PCB can detect faults in the system and display error codes through the control panel. Common issues might include faulty sensors, electrical connections, or other system malfunctions. The error code will guide you in troubleshooting the problem.
-
Common Signs of a Faulty PCB:
- No Heat or Heating Delays: If the PCB is faulty, it may prevent the heater from igniting or cause a delay in the ignition process, resulting in no heat output.
- Error Codes or Flashing Lights: The control panel may display error codes or flashing warning lights, indicating a problem with the PCB or other parts of the heating system.
- Inconsistent Heating: A malfunctioning PCB can cause the heater to operate erratically, providing inconsistent heating or not maintaining the desired room temperature.
- Failure to Start: If the PCB fails, the ignition process will not occur, meaning the heater will not start.
- System Shutdown: If the PCB detects a critical fault, such as a safety issue, it may automatically shut down the heater to avoid further damage.
-
Replacement Considerations:
- Correct Part Number (PN. 628820): Always ensure that the replacement PCB is the correct part for your Braemar BM 325 & X gas ducted heater. The part number PN. 628820 is specifically designed for this model, ensuring compatibility and proper function.
- Installation by Professionals: Replacing the PCB is a complex task and should be carried out by a licensed HVAC technician to ensure safety and correct installation. A technician will also verify that the replacement PCB is functioning properly after installation.
-
Installation Process:
- Turn Off Power and Gas: Before replacing the PCB, make sure the power to the heater is switched off and the gas supply is turned off to avoid electrical shock or gas leaks.
- Access the PCB: Open the front or side panel of the heater to locate the existing PCB. You may need to remove screws or panels to access the circuit board.
- Disconnect the Old PCB: Carefully disconnect all electrical wires and components connected to the faulty PCB. It is helpful to note the wiring configuration, or take photos, so that the new PCB can be connected in the same way.
- Install the New PCB: Place the new PN. 628820 PCB in the same position as the old one. Make sure it is securely attached to prevent electrical or mechanical issues.
- Reconnect the Wires: Reconnect all the wiring to the new PCB according to the original configuration. Ensure that the connections are tight and properly aligned.
- Test the System: After the new PCB is installed, restore power to the system and test the heater. Check that it ignites correctly, the blower motor operates, and the temperature regulation functions as expected.
-
Maintenance Tips:
- Regular Inspections: To ensure the proper functioning of your Braemar BM 325 & X heater, schedule regular inspections and maintenance. This allows technicians to check for issues with the PCB and other system components before they cause larger problems.
- Keep the Heater Clean: Dust and debris can build up inside the heater, affecting the performance of the components. Regular cleaning can prevent overheating and ensure airflow is not obstructed, which can affect the PCB’s performance.
- Annual Servicing: It is recommended to have your heater serviced once a year by a professional to check all components, including the PCB, and ensure optimal operation.
Conclusion:
The Braemar BM 325 & X PCB Circuit Board BSC 3 Star Gas Ducted Heater PN. 628820 is crucial for the proper functioning of your gas ducted heating system. If you're experiencing problems like no heat, inconsistent heating, or error codes, it might be due to a malfunctioning PCB. Replacing the faulty PCB with the correct PN. 628820 part ensures that your heater will run efficiently and safely.
For safe and effective installation, it’s recommended to have a licensed HVAC technician replace the PCB. Regular servicing and maintenance will help extend the life of the heater and ensure its efficient operation.
