Technical Overview
Overview & Function
The Dometic 3314471.013 is the fan motor assembly for listed Penguin II rooftop air conditioners. The fan motor drives condenser and evaporator airflow, so a failing motor announces itself with humming, slow starts, weak cooling, or a seized shaft on hot days. Replacing the same-number 3314471.013 assembly restores designed airflow and lets the refrigeration circuit perform to rating again.
Fitment & Compatibility
Confirm 3314471.013 on your motor nameplate or the Penguin II service parts list, including the suffix digits. The assembly mounts to the factory motor brackets and connects to the original capacitor and wiring for that model. Because shaft length, rotation, and mounting ears are model-specific, match the complete number rather than substituting by appearance.
Technical Construction & Specifications
The assembly includes the motor wound to the Penguin II specification with factory shaft dimensions, mounting provisions, and lead configuration for the model's capacitor circuit. Bearings are sealed for rooftop duty with moisture and temperature cycling, and the shell finish resists corrosion in the condenser airstream. Electrical ratings follow the dataplate of the original motor for the listed Penguin II variants.
Installation & Maintenance Guidelines
Disconnect all AC power and confirm zero energy before opening the shroud. Photograph wiring, discharge the capacitor with proper procedure and tools, then unmount the old motor and transfer the fan hardware if the service guide directs. Mount the new 3314471.013 assembly, reconnect leads and capacitor per the diagram, and spin-check for clearance. Restore power and verify both fan speeds, cooling performance, and normal amperage before closing the shroud.
