Keep your NuTone 769RL bath fan operating efficiently with genuine OEM replacement parts from Repair Clinic. The NuTone 769RL is a ceiling-mounted bathroom exhaust fan sold in A unit and B unit motor assembly configurations that mount into the same 769RL housing. The B unit is the current production motor assembly and the A unit was the earlier version. Proper bathroom ventilation requires the fan to operate at full airflow capacity. A blower wheel coated with lint deposits delivers a fraction of the rated cubic feet per minute and allows moisture to remain in the bathroom, promoting mold growth on walls and ceilings. Repair Clinic stocks genuine NuTone OEM parts for the 769RL including the NuTone bath fan motor parts and NuTone blower wheel parts.

NuTone 769RL: A Unit vs B Unit Motor Assembly and the 763RL Relationship
The NuTone 769RL is available with an A unit motor assembly (earlier production) and a B unit motor assembly (current production). Both units install into the same 769RL housing. The NuTone 763RL is a related model in the same product family and some motor and blower wheel parts are interchangeable between the 763RL and 769RL. Always confirm the specific unit letter designation from the installed housing label before ordering a replacement motor assembly to ensure you receive the correct mounting bracket orientation and wiring plug configuration.
Most Replaced Parts on the NuTone 769RL
Motor Assembly for the NuTone 769RL
The motor assembly drives the blower wheel that generates exhaust ventilation airflow. The 769RL motor assembly is sold as a complete unit including the motor, blower wheel, and mounting bracket. Confirm whether your 769RL uses the A unit or B unit motor assembly from the label on the installed housing before ordering, as the mounting bracket orientation differs between the two production versions.
Blower Wheel for the NuTone 769RL
The blower wheel mounts to the motor shaft and generates the airflow that draws moisture and odors from the bathroom. Lint and dust accumulate on the blower wheel blades over time, reducing airflow capacity and increasing the load on the motor bearing. Cleaning the blower wheel annually with a vacuum and soft brush maintains rated airflow performance and extends motor bearing life.
Grille Assembly for the 769RL
The grille covers the fan opening and mounts with spring clips that release by squeezing and pulling straight down. A yellowed, cracked, or damaged grille can be replaced without disassembling the motor or blower assembly.
Duct Connector and Housing Components
The duct connector joins the fan housing to the exhaust duct run. A duct connector that has pulled loose from the fan housing allows exhaust air to discharge into the ceiling cavity rather than to the exterior, causing moisture accumulation in the attic or ceiling space. Inspect the duct connection annually when cleaning the blower wheel.

NuTone 769RL Bath Fan Parts FAQ
What is the NuTone 769RL and what are its A unit and B unit designations?
The NuTone 769RL is a ceiling-mounted bathroom exhaust fan. The A unit and B unit designations identify the motor and blower assembly sold separately from the complete fan housing. The B unit is the current production motor assembly and the A unit was the earlier production version. Both units mount into the same 769RL housing.
Is the NuTone 769RL the same as the NuTone 763RL?
The NuTone 769RL and 763RL are related bath fan models in the same NuTone product family. Some motor and blower wheel parts are interchangeable between both models. Always verify the specific unit designation from the installed housing label before ordering a motor or blower wheel replacement.
Why is my NuTone 769RL running but producing very little airflow?
Reduced airflow from the NuTone 769RL is most commonly caused by a blower wheel that has accumulated heavy lint and dust on its blades, reducing the wheel’s ability to move air. Cleaning the blower wheel thoroughly is the first step before ordering any replacement parts. If cleaning does not restore airflow, the blower wheel may need replacement.
How do I replace the motor in a NuTone 769RL?
Turn off the circuit breaker serving the fan. Remove the grille by squeezing the mounting clips and pulling it straight down. Disconnect the motor plug from the wiring harness in the housing. Unscrew the motor mounting bracket and slide out the complete motor and blower wheel assembly. Install the new assembly, reconnect the plug, and restore power before testing.
