Titus HVAC 31671879 Motor
The Titus HVAC 31671879 Motor is a high-efficiency 3/4hp 120V motor engineered specifically for TQS fan powered terminals. As a veteran-grade HVAC blower motor replacement, this unit features a heavy-duty cast-iron frame and an open enclosure design to optimize thermal management during continuous operation. This single-phase motor is factory-calibrated for pressure-independent operation, utilizing an integrated PWM controller that responds to 1.0V to 10.0V signals. This ensures precise airflow control and significant energy savings when compared to traditional PSC motors. Designed for seamless integration into VAV box systems, the 31671879 provides bidirectional (CW/CCW) rotation capabilities and built-in thermal overload protection to safeguard the windings against overheating in high-static applications. For contractors performing a commercial HVAC motor repair, this OEM Titus component matches exact factory specifications for the Titus TQS Series, ensuring the fan curve and power consumption remain within original design parameters.
Key Benefits- Optimized Efficiency: Engineered for Titus TQS terminals, delivering up to 70% efficiency across the standard 300-1200 RPM operating range.
- Rigid Construction: Built with a cast-iron frame for superior vibration dampening and long-term structural integrity in air handler environments.
- Advanced Control: Features a factory-installed PWM controller for precise 120V single-phase performance and pressure-independent fan speed modulation.
- Safety Integrated: Includes automatic reset thermal overload protection to prevent motor failure during restrictive duct conditions or high-ambient operation.
- Universal Compatibility: Designed for VAV fan powered boxes, supporting both residential and light commercial air delivery systems.
Is the 31671879 motor compatible with non-Titus VAV boxes?
While technically a single-phase 120V motor, the Titus 31671879 is specifically programmed and calibrated for Titus TQS and TQP fan terminals. Using it in other brands may require manual recalibration of the PWM signal to match the specific fan wheel requirements.
How do I troubleshoot a motor that won't start?
Verify 120VAC at the high-voltage leads and check for a valid 1V-10V DC signal from the HVAC controller to the PWM board. If voltage is present but the motor is stalled, check the thermal overload and ensure the fan wheel rotates freely without mechanical binding.
Does this motor require a separate capacitor?
As a TQS-specific high-efficiency motor, it is often paired with a 25 MFD 370V oval capacitor if the specific terminal configuration requires it. Always check the wiring diagram on the Titus HVAC terminal before finalizing the installation.
