Product Description
The Braemar TG TH PCB 3 Star Gas Ducted Heaters PN. 628820 is an essential component in the Braemar gas ducted heating systems. The PCB (Printed Circuit Board) plays a key role in controlling and managing the operation of the heater, ensuring it functions safely and efficiently.
Key Features and Details:
-
Function of the PCB:
- The PCB serves as the brain of the heating system, managing all the electrical signals and communication between various components like the blower motor, gas valve, thermostat, and sensors.
- It monitors inputs from various sensors, such as temperature and pressure sensors, and adjusts the heater’s operation accordingly to maintain the desired room temperature.
- The PCB is responsible for controlling the ignition sequence, the blower fan operation, and other key functions required for the gas heater to operate properly.
-
Role in the Heating System:
- Temperature Control: It ensures the system maintains the correct temperature by regulating the burner and blower fan's performance.
- Safety Protocols: The PCB monitors the performance of key components to detect faults and activate safety protocols if any problems occur (e.g., overheating, gas flow issues, or fan malfunctions).
- Energy Efficiency: By controlling the operation of the system's components, it helps the heater operate efficiently, contributing to overall energy savings.
-
Common Symptoms of a Faulty PCB:
- No Heat Output: If the PCB is faulty, the heater might fail to ignite or distribute heat properly, resulting in no warm air being generated.
- Error Codes or Flashing Lights: Many modern systems have an error code system that signals when there is a problem with the PCB. This could include flashing lights on the control panel or a specific error code indicating a PCB malfunction.
- Inconsistent Heating: If the PCB is malfunctioning, the system may not regulate the temperature properly, leading to uneven or inconsistent heating in different areas of the home.
- Failure to Start or Shutdown: The heater might fail to start up or shut down unexpectedly due to PCB issues in managing the sequence of operations.
- Unusual Noises: A faulty PCB can cause electrical issues that may lead to buzzing, clicking, or other unusual noises from the system.
-
Replacement Considerations:
- Correct Part Number (PN. 628820): To ensure compatibility, make sure the replacement PCB has the exact part number PN. 628820, which is specifically designed for the Braemar TG TH 3 Star Gas Ducted Heaters.
- Compatibility: Check the specifications and model of your heating system to ensure the PCB is compatible with your unit. It is crucial to match the model and functionality of the PCB to avoid any compatibility issues.
- Professional Installation: Given the complexity of installing a new PCB, it’s highly recommended to have a professional HVAC technician handle the replacement to avoid damaging the system or improperly wiring the new board.
-
Installation Process:
- Turn Off Power and Gas Supply: Before working on the heater, make sure to turn off both the electrical power and gas supply to prevent any accidents.
- Access the PCB: Open the front panel of the heater to access the existing PCB. You may need to remove screws or panels to get to the board.
- Disconnect the Old PCB: Carefully disconnect the wiring from the old PCB. Take note of the wiring configuration, as you will need to connect the new PCB in the same way.
- Install the New PCB: Mount the new PN. 628820 PCB in the same position as the old one. Ensure that it is securely attached and that all the connections are properly aligned.
- Reconnect the Wiring: Reconnect all the wiring to the new PCB according to the original configuration. Ensure all electrical connections are secure and properly placed.
- Test the System: Once the new PCB is installed, turn the system back on and check for correct operation. Ensure that the system ignites, the blower fan operates, and the temperature control functions as expected.
-
Maintenance Tips:
- Regular System Checks: Regularly check the system’s performance to ensure it’s operating correctly. If you notice any unusual behavior or warning signs like error codes or malfunctioning components, consider inspecting the PCB.
- Keep the Heater Clean: Ensure the heater is free of dust and debris, as dirt buildup can cause overheating or damage to sensitive electronic components like the PCB.
- Professional Servicing: It's advisable to have your system serviced annually by a qualified HVAC technician to ensure that all components, including the PCB, are functioning optimally.
Conclusion:
The Braemar TG TH PCB 3 Star Gas Ducted Heaters PN. 628820 is a critical component that controls and manages the electrical functions of the Braemar TG TH heating system. If your heater is not functioning correctly, showing error codes, or has no heat output, a faulty PCB may be the cause.
By using the correct PN. 628820 replacement PCB, and with professional installation, you can restore the heater’s functionality and ensure it operates efficiently and safely.
