Replacing the run capacitor is recommended when installing a new HVAC blower motor to ensure optimal torque and efficiency

making it suitable for motor and resistive loads

remove the protective cap and turn the setting screw

While it can physically fit

The unit delivers a linear 0 to 10 Vdc output signal over its 0 to 100 psi range

Carrier HC39SB115 Blower Motor 318172-701 Replacing the run capacitor isThe Carrier HC39SB115 Blower Motor is a high efficiency Direct Drive PSC Motor engineered for consistent airflow in residential and light commercial forced air systems. Operating at 115V with a 1 4 HP output, this 4 speed motor provides 1075 RPM performance to meet original equipment specifications. As a Permanent Split Capacitor design, it utilizes a 7. 5 MFD at 370V capacitor (sold separately) to maintain high torque and energy efficient operation.
