• Direct OEM Compatibility: Seamlessly replaces Sterling 11J31R01125 and Fasco 7121-5949 without field modifications.
• High-Speed Efficiency: The 3000 RPM output ensures reliable drafting through restrictive high-efficiency heat exchangers.
• Optimized Performance: Specifically calibrated for Sterling QV series (QVEF, QVED, QVES) and equivalent unit heaters.
• Industrial Build Quality: Engineered as a high-torque unit heater inducer to handle repeated startup cycles in demanding environments.

Common Questions:

Which heater models use this inducer motor?
This part is the primary power vent assembly for Sterling QV Series units, including common model numbers like QVEF030, QVEF200, and QVED400, as well as several Grainger/Dayton crossover models.

Can I use this to replace a 208-230V motor?
No, this is a 115V inducer. Always verify the voltage on your existing motor’s nameplate and check your control board output before ordering to prevent electrical failure.

Why is my inducer motor making a grinding noise?
Mechanical noise or vibrations usually indicate bearing wear or a compromised impeller. Replacing the draft inducer assembly early prevents total system lockout during cold-weather calls.
