Product Description
The Braemar TQM 520 Gas Ducted Heater Blower Fan Motor Single Speed 315 Watt PN. 076935 is an integral component in the Braemar TQM 520 gas ducted heating system. This motor powers the blower fan that circulates warm air through the ductwork, helping to maintain a consistent and comfortable temperature throughout your home or building.
1. Function of the Blower Fan Motor:
- The blower fan motor in the Braemar TQM 520 heater moves warm air produced by the gas burner through the ducts and into the rooms, ensuring efficient heat distribution.
- This motor operates at single speed, meaning it runs at a constant, fixed speed to provide continuous airflow throughout the heating process.
- With a 315-watt power rating, it has enough capacity to circulate air effectively through the heating system.
2. Key Features:
- Single Speed: The motor operates at one consistent speed, ensuring uniform airflow without adjusting to changes in heating demand. This is ideal for systems where steady airflow is sufficient.
- 315 Watt Power: The 315-watt motor provides enough power to move air through the system, ensuring that the heater can maintain effective heating performance throughout your home or building.
- Durable and Reliable: Designed for long-term use, the motor is engineered to handle continuous operation, offering dependable performance during the heating season.
3. Common Symptoms of a Faulty Blower Fan Motor:
- No Airflow: If the motor fails, the fan will not operate, and as a result, warm air will not circulate, making the heater ineffective.
- Inconsistent Airflow: A faulty motor may cause intermittent airflow, leading to uneven heating in the rooms. Some areas may be too hot while others remain cool.
- Unusual Noises: Grinding, squealing, or buzzing sounds are often indicative of worn bearings, damaged parts, or motor failure.
- Overheating: A failing motor may overheat, causing the system to shut down automatically to protect the components. This can trigger a safety lockout or error code.
- Error Codes: If the motor is malfunctioning, your Braemar TQM 520 heater may display error codes or enter a lockout mode.
4. Replacement Considerations:
- Correct Part Number (PN. 076935): Ensure that you use the exact replacement motor with part number PN. 076935 for compatibility with your Braemar TQM 520 system.
- Motor Specifications: The replacement motor should be a 315-watt, single-speed motor to match the specifications required for your heater.
- Professional Installation: Replacing the motor involves electrical and mechanical work, which can be complex. It's recommended to hire a licensed HVAC technician to ensure proper installation and safety.
5. Installation Process:
- Turn Off Gas and Power: Before starting any work, make sure to turn off both the gas supply and electrical power to the system to ensure safety.
- Access the Blower Motor: Remove the cover or front panel of the heater to gain access to the blower fan motor. This might involve unscrewing or unclipping the cover.
- Disconnect the Old Motor: Carefully disconnect the wiring from the old motor, and remove any screws or bolts that secure it in place.
- Install the New Motor: Place the new 315-watt motor in the correct position, ensuring it's securely fastened and the wiring is reconnected as per the manufacturer’s instructions.
- Test the System: Once the new motor is installed, turn the system back on and check that the blower fan is working properly, and air is circulating throughout the system.
6. Maintenance Tips:
- Regular Cleaning: Dust and debris can accumulate on the blower fan and motor, reducing efficiency. Clean the motor and fan regularly to ensure the system operates efficiently.
- Inspect for Wear: Check the motor for any signs of wear, such as strange noises or vibrations, which could indicate the need for replacement.
- Lubrication (if required): Some motors may require periodic lubrication. If the motor has lubrication points, follow the manufacturer's guidelines to ensure proper maintenance.
7. Conclusion:
The Braemar TQM 520 Gas Ducted Heater Blower Fan Motor Single Speed 315 Watt PN. 076935 is essential for circulating warm air through the heating system and ensuring even heat distribution throughout your home. If the motor fails, it will cause issues like no airflow or inconsistent heating. Replacing the motor with the correct PN. 076935 part number will restore the heater's functionality.
For safe and proper installation, it is advisable to consult a licensed HVAC technician if you're not comfortable handling the replacement yourself.
