20942 Blower Motor 115V 3-Speed Replacement

This 3-Speed Blower Motor 20942 is built for dependable performance, smooth airflow, and quiet operation—everything your heating system needs to get back to doing its job without the drama. Designed as a direct replacement for Fasco 71731407 and Silent Flame SF782012, it fits right in without forcing you into complicated modifications or guesswork.

Built for Consistent, Everyday Performance

With a 1/50 HP motor, this unit delivers steady airflow without overworking your system. Whether you're maintaining a gentle heat circulation or pushing warm air more aggressively, the three-speed functionality (1550 / 1300 / 1100 RPM) gives you flexibility to match your comfort level.

Running on 115V at 60Hz and drawing just 0.95 amps, it’s efficient enough to keep energy use in check while still delivering the performance you expect.

Three Speeds, Total Control

Not every day calls for the same heat output—and this motor gets that.

• High speed (1550 RPM): When you need fast, powerful airflow

• Medium speed (1300 RPM): Balanced performance for everyday use

• Low speed (1100 RPM): Quiet, steady circulation without excess noise

The result? A more comfortable space without constantly adjusting your system.

Designed with Protection in Mind

This blower motor is thermally protected, which means it automatically safeguards itself from overheating. That’s one less thing to worry about—especially during long heating cycles when your system is working overtime.

Straightforward Replacement, Less Hassle

If you’re replacing a worn-out Fasco 71731407 or Silent Flame SF782012, this motor is designed to step in seamlessly. No complicated installs, no unnecessary modifications—just a practical, reliable fix that gets your system back on track.
