This aftermarket replacement RV air conditioner motor is designed to directly replace the Century ORV4540, Dometic 3105054.005, and Duo Therm F42 series motors. Engineered for three-speed operation, it features a thermally protected sleeve bearing to enhance durability and performance under typical RV rooftop conditions. The motor’s 1/5 horsepower rating and 115V AC power supply make it suitable for a variety of RV air conditioning units, providing reliable rotation at 1,650 RPM in a counterclockwise direction from the lead end. The inclusion of a 5 MFD capacitor with two pins ensures proper start and run functions, while the insulation class B rating allows operation in ambient temperatures up to 40°C.
The motor’s frame size of 42 with a 5" diameter complements the semi-enclosed, air-over design, allowing efficient cooling during operation. Mounting is facilitated by three ear brackets with 0.56" holes spaced on a 6" bolt circle plus one extended bolt at the lead end, ensuring secure installation. The dual shaft design measures 4" by 1/2" by 2-1/2", compatible with the original equipment’s mechanical connections. Wiring leads include both 42" lengths with AMP pins and 26" leads with female spade terminals for flexible connection options. Weighing 5 kg, this motor balances sturdy construction with manageable handling during replacement.
Ideal for RV owners seeking a precise, aftermarket alternative to original motor units, this part aligns with key model numbers and specifications to maintain the performance of rooftop air conditioning systems.
