Product Description
The Braemar TQA 520 Gas Ducted Heater Blower Fan Motor Single Speed 315 Watt PN. 076935 is a key component of the Braemar TQA 520 gas ducted heating system. This motor is responsible for driving the blower fan, which circulates warm air throughout the ductwork and into the living spaces, ensuring your home remains comfortably heated.
1. Function of the Blower Fan Motor:
- The blower fan motor powers the fan that moves the warm air created by the heater into the ducts. This is essential for efficient heat distribution throughout the home.
- Operating at a single speed, this motor provides a consistent airflow throughout the heating cycle. It's ideal for systems where variable speeds are unnecessary, and steady airflow is sufficient.
- 315-watt power: The motor is rated at 315 watts, which provides sufficient power to push air through the entire system, ensuring that heat is distributed effectively and evenly across the house.
2. Key Features:
- Single Speed Operation: The motor operates at a fixed speed to provide constant airflow, ensuring consistent heating across all rooms.
- 315 Watt Power: The 315-watt motor is powerful enough to ensure effective airflow through the system, maintaining even heat distribution.
- Durability: The motor is built to last, capable of handling continuous use during the heating season without compromising performance.
3. Common Symptoms of a Faulty Blower Fan Motor:
- No Airflow: If the motor fails, it will prevent the blower fan from operating, which will lead to a lack of warm air circulation and ineffective heating.
- Inconsistent Airflow: A malfunctioning motor may cause inconsistent airflow, leading to uneven heating in the house.
- Unusual Noises: If you hear strange sounds such as grinding or squealing, it may indicate the motor’s bearings are worn or there’s internal damage.
- Overheating: A failing motor may overheat, triggering an automatic shutdown to protect the system. This could result in error codes or safety lockouts.
- Error Codes: Modern heating systems like the Braemar TQA 520 are equipped with safety features, and they may display error codes or enter lockout mode when the blower motor is not functioning properly.
4. Replacement Considerations:
- Correct Part Number (PN. 076935): Ensure that you use the correct replacement motor with part number PN. 076935 to maintain compatibility with your Braemar TQA 520 system.
- Motor Specifications: The replacement motor must match the original 315-watt, single-speed specifications for optimal performance.
- Professional Installation: Replacing the blower motor involves working with electrical and mechanical components, so if you're not comfortable with these tasks, it’s highly recommended to hire a licensed HVAC technician to handle the replacement safely and correctly.
5. Installation Process:
- Turn Off Gas and Power: Before working on the system, always ensure that both the gas supply and electrical power are turned off for safety.
- Access the Blower Motor: To access the motor, you will need to remove the front panel or cover of the heater. This may involve unscrewing or un-clipping the housing.
- Disconnect the Old Motor: Disconnect the wiring from the old motor and remove any screws or bolts that secure it in place.
- Install the New Motor: Position the new 315-watt motor in place, ensuring it's securely fastened. Reconnect the wiring, making sure the connections are accurate according to the manufacturer’s instructions.
- Test the System: After installation, turn the power and gas back on and test the system to ensure that the motor is working correctly and warm air is circulating properly.
6. Maintenance Tips:
- Regular Cleaning: Clean the motor and fan regularly to ensure there is no dust or debris buildup that could reduce airflow or efficiency.
- Inspect for Wear: Periodically inspect the motor for any signs of wear, such as unusual noises, vibrations, or decreased airflow.
- Lubrication (if applicable): If the motor has lubrication points, follow the manufacturer’s recommendations to keep it well-lubricated and prevent excessive wear.
7. Conclusion:
The Braemar TQA 520 Gas Ducted Heater Blower Fan Motor Single Speed 315 Watt PN. 076935 is essential for ensuring that your gas ducted heating system circulates warm air effectively. A malfunctioning motor can lead to a lack of airflow and uneven heating. Replacing the motor with the correct PN. 076935 part will restore the functionality of your heater and ensure consistent comfort in your home.
If you're unsure about replacing the motor yourself, it's always a good idea to consult a licensed HVAC technician to ensure proper and safe installation.
