Bathroom Fan Motor Compatible with Nutone QT-110N Series - Quiet 100

Our review of this replacement bathroom fan motor finds it best for homeowners and maintenance pros who need a direct, no-fuss swap for Nutone QT series units. The motor delivers a clear practical win: it restores ventilation quickly with a rated 100 CFM and a modest 3.5 sones sound level, so bathrooms clear steam faster without loud noise. Installation is straightforward for someone comfortable with basic wiring and in-ceiling access, and the unit is sized to match the original assembly so cutters or major disassembly are rarely required.

Key Features

• Compatibility: Direct replacement for many Nutone QT models, which reduces time spent searching for a matching assembly.
• Performance: Rated at about 100 CFM with 1450 RPM to clear moisture and odors efficiently in small to medium bathrooms.
• Quiet operation: 3.5 sones configuration keeps noise low compared with older or worn motors, making it less intrusive in daily use.
• Compact size: The 6.69 in x 6.10 in x 4.72 in housing is designed to fit existing housings without cutting or plaster work.
• Simple electrical spec: Runs on 120 Volt AC at 60Hz and draws about 0.3A, matching typical residential circuits for easy replacement.
• Included assurance: Packaged with a 5-year assurance and seller support for fit or damage concerns.

Who It's For

This motor is ideal for homeowners, landlords, and building maintenance staff who already own a Nutone QT series exhaust fan and want a cost-effective repair instead of replacing the whole fixture. It suits small to medium bathrooms where a 100 CFM output and quieter operation are desirable.

Because the unit is a direct replacement assembly, it is not targeted at custom ventilation projects that need atypical airflow, exotic voltages, or different mounting geometries. If you require higher CFM for a large bathroom or a different airflow profile, look for a fan designed for that capacity.
