How do I know if this motor fits my furnace?
Verify the part number on your existing motor or consult your furnace's service manual. This 48-frame motor is a standard fit for many Armstrong and Lennox units requiring a 1075 RPM 230V 1/2 HP motor.

Can I use a different capacitor with this motor?
It is essential to use the capacitor MFD rating specified on the new motor's nameplate to ensure proper starting torque and to prevent internal overheating.

Is this motor reversible?
Standard R47543-001 motors are designed for specific rotation directions. Always confirm the rotation (CCW or CW) against your original blower wheel requirement before installation.
