12V DC drive head motor for Dometic 9100 Power Patio Awnings. Found on the right side of the awning, connecting the roller tube to the extension hardware. White finish. 13-1/2" overall length. Compatible with 910, 915, 916, and 917 models. Cross-references 3310423.137B and 3310419.209B.
The Dometic 3310423.209B is the 12V DC drive head motor used on the right side of a Dometic 9100 Power Patio Awning. It connects the roller tube to the extension hardware and is the component that actually powers the awning open and closed at the push of a button. When this motor fails, the awning typically stops responding to the switch, moves unevenly, or requires manual assist to extend or retract, and replacing the drive head restores full powered operation without needing to replace the entire awning assembly.
This part is specific to the right-hand side of the awning — the 9100 series uses a torsion assembly on the opposite (idler) side that is a separate, non-motorized part. The white finish matches the majority of factory 9100 awning hardware, and the 13-1/2" overall length with a 5" wire lead and connector is designed to drop into the existing wiring harness without modification.

This is the right-hand, motorized drive head. The opposite (left/idler) side of a 9100 awning uses a separate, non-motorized torsion assembly and is not interchangeable with this part. Confirm which side of your awning has failed before ordering.
The same drive motor is available in black as Dometic 3310423.209U, for 9100 awnings with black hardware trim.
