Use this 17-rpm auto-lift motor to replace the damaged one in a Dometic FanTastic B Series roof vent with a powered lift arm.
Features:
Note: This replacement motor is designed for use in Dometic FanTastic roof vents with 17-rpm motors manufactured in 2014 or after. If your fan is of a lower rpm or manufactured before 2014, this motor will still work, but you will need to cross the wires. For example, instead of red to red and black to black, you will need to connect the red wire to the black wire and the the black wire to the red wire.

Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a quick look at this replacement off-white 17 rpm lift motor for the Fan-Tastic Vent B Series roof vents with powered lifts. Now, if you're needing to replace a damaged 17 rpm auto-lift motor in your Fan-Tastic Vent B Series roof vent with a powered lift arm, then this just might be what you need. This replacement motor is designed for use in the Fan-Tastic Vent roof vents with a 17 rpm motor manufactured in 2014 or after. Now, if your fan is of a lower rpm or if it's manufactured before 2014, I have good news for you.
This will still work but you will need to cross the wires. For example, instead of the red wire, let me get you in frame here. Instead of the red to red and black to black, you would just need to connect the red wire to the black wire and the black wire to the red wire. And as I mentioned at the beginning of our time together, this is off-white in color. And you are going to get everything that you see here along with the mounting screws for your installation.
Well, that's gonna conclude our brief look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

I did reach out to the manufacturer and it depends on the model number of the fan as to whether it can be switched to a manual operation. The lift motor is a replacement for more than one model. The knob is going to be difficult to turn, even if the fan has a manual mode.

After one year of use, the replacement motor continues to work as it should. Needless to say, I am pleased with its performance.
