Product Description
The Braemar Gas Ducted Heater PCB Control Board (Part No. 651989) is an important component in Braemar gas ducted heating systems, specifically designed to work with the TQM 6 model. The PCB (Printed Circuit Board) is responsible for controlling and managing the various functions of the heater, including regulating temperature, fan speeds, and gas flow. It acts as the brain of the system, ensuring everything operates efficiently and safely.
Key Features and Function of the Braemar Gas Ducted Heater PCB Control Board (Part No. 651989):
-
Compatibility:
- This control board is specifically designed to fit Braemar TQM 6 gas ducted heaters. It ensures proper communication between various components of the heater, such as the gas valve, fan motor, and thermistor.
-
Central Control Unit:
- The PCB control board serves as the central processing unit (CPU) of the gas heater. It interprets input from the thermostat and sensors, sending commands to other parts of the system to maintain a consistent room temperature.
-
Regulation of Heating Functions:
- The PCB is responsible for activating the gas valve, which controls the flow of gas to the burner. It also regulates the fan motor to distribute warm air evenly throughout your home.
-
Temperature and Safety Management:
- The control board continuously monitors the heater's temperature and ensures that it doesn't overheat or operate outside of safe parameters. If it detects a problem, such as an issue with airflow, the PCB can trigger safety shutdowns to prevent damage to the unit or potential hazards.
-
Error Detection and Diagnostic Features:
- Many modern PCB control boards, including this one, have built-in diagnostic capabilities. The control board can detect faults or malfunctions in components like the fan, thermistor, or gas valve, and provide error codes to help you identify the problem.
-
User Interface Communication:
- The PCB communicates with the user interface (such as a remote control or thermostat) to adjust temperature settings, fan speeds, and other parameters according to your preferences. It ensures smooth communication between the user and the heater’s internal systems.
-
Durability and Reliability:
- The PCB is designed for long-term operation and is built to withstand the rigors of regular heating cycles. It's engineered to be reliable and resistant to wear and tear, ensuring consistent performance over time.
Symptoms of a Faulty PCB Control Board:
-
No Heat Output:
- If the PCB control board is malfunctioning, the heater may fail to produce any heat. This could be due to issues with the gas valve, burner ignition, or fan operation.
-
Error Codes or Warning Lights:
- The control board may display error codes or activate warning lights to indicate problems with components such as the gas valve, thermistor, or fan motor. These codes are helpful for diagnosing issues.
-
Inconsistent Temperature Control:
- If the PCB is malfunctioning, the heater may struggle to maintain a consistent temperature. You might notice that the heater overheats or fails to reach the set temperature.
-
Unusual or Noisy Operation:
- A malfunctioning control board can cause irregular fan speeds or trigger the fan motor to operate erratically. If the board sends incorrect signals to the fan motor, it could result in unusual noises or erratic air circulation.
-
Failure to Start:
- If the PCB is damaged, the heater might fail to start or respond to thermostat adjustments. This could be due to an issue with the board not sending the correct signals to activate the gas flow or fan motor.
How to Replace the Braemar Gas Ducted Heater PCB Control Board (Part No. 651989):
-
Turn Off Power and Gas Supply:
- Before attempting any repairs, ensure that the power supply to the heater is turned off, and the gas supply is shut off to prevent accidents or injury.
-
Remove the Access Panel:
- You will need to remove the access panel to reach the control board. Depending on your model, this might require unscrewing or detaching the panel. Be sure to keep any screws or fasteners in a safe place.
-
Disconnect the Wiring:
- Carefully note the wiring configuration of the old PCB. Disconnect the wiring from the old control board. You may want to take a photo or label the wires to ensure they are reconnected correctly on the new board.
-
Remove the Faulty PCB:
- The control board is typically secured with screws or clips. Carefully remove the old PCB from its mounting position.
-
Install the New PCB:
- Place the new Braemar PCB Control Board (Part No. 651989) into the mounting position. Secure it with screws or clips as needed.
-
Reconnect the Wiring:
- Reconnect the wiring to the new control board. Ensure each wire is connected to the correct terminal, following the notes or photo you took earlier.
-
Reassemble the Heater:
- Once the new PCB is installed and wired, replace the access panel and secure it with screws or fasteners.
-
Turn on the Heater and Test:
- Turn the power and gas supply back on and test the heater. Set the thermostat to the desired temperature and check for proper operation. Make sure the fan, gas flow, and temperature regulation are working as expected.
-
Check for Error Codes or Malfunctions:
- If the heater displays any error codes or malfunctions, refer to the Braemar user manual to troubleshoot further. Ensure the new control board is functioning correctly and communicating with all system components.
Maintenance Tips for Your Braemar Gas Ducted Heater PCB Control Board:
-
Regular Inspection:
- Periodically check the control board for any signs of wear, damage, or electrical faults. Look for burn marks or corrosion on the connections that may indicate problems.
-
Clean the Heater:
- Dust and debris can accumulate around the PCB. Clean the surrounding area to ensure airflow around the board remains unobstructed. Be careful not to damage any electrical components.
-
Monitor Error Codes:
- If the system is equipped with error codes, always take note of them and address any issues promptly. If you continue to get error codes after replacing the control board, it may indicate a larger system problem.
-
Test Thermostats and Sensors:
- The PCB relies on input from thermostats and sensors. If you experience temperature regulation issues, check that these components are working properly as well.
-
Prevent Overheating:
- Ensure that your gas ducted heater has proper ventilation and isn’t blocked. Overheating can cause damage to the PCB and other components.
Conclusion:
The Braemar Gas Ducted Heater PCB Control Board (Part No. 651989) is an essential part of the TQM 6 model and serves as the control center for managing your heater's operations. If you're experiencing issues like no heat, temperature inconsistencies, or error codes, the PCB may be the cause.
