Features:
Note: This replacement motor is designed for use in Dometic Fan-astic roof vents with 17-rpm motors manufactured in 2014 or after.

plug and play can't beat that.half the price of costco
the crew was very helpful trying to get me the correct parts.
Product was match to OEM part.
Fit perfect
Fit correctly and matched the color of my wiring also
Good price, timely delivery and Josh kept me informed every step of the way. Just installed the lift motor and it works perfect.
Love shopping with this company! From placing the order to receiving it! The customer service is top notch! I highly recommend buying from this company! Have and will continue to do business here!
Working as it should. I was reading reviews on this unit that said to reverse polarity on other sites. No need for that. This is ove course bit faster than the 8 rpm I replaced but the fit is exact. No problem. I'll buy again if the need arises. Nice people to work with and fast shipping.
Fast shipping and part worked well. I would definitely use them again as it came boxes well and worked as it should.
Replacement motor worked GREAT. Fit Gr eat!
Only needed the housing. I wish it was available as metal. Easy swap.
Great service and delivered timely.
Works as ad
Exact fit. The spline shaft on the replacement lift motor is metal vs. plastic on the original motor which stripped and cracked, requiring replacement. Anticipate better longevity from this unit.
The exact replacement part for my fantastic fan and only took a couple of minutes to install and works perfectly.
Works like a new one. Thanks for the he lp!
Installation was simple and it works as it should. Thank you for having the parts! :)
Thank you, Showed up fast.
Arrived fast and in perfect shape. Installed and working in under 10minutes. Great service.
So far so good… tried two units from Amazon both failed…hoping for a better result here

I might be a little biased, but I like to think we're a step above the online jungle. I hope this one treats you much better!
Works as promised. Love the tips like reversing the wires. Probably would've never figured that out on my own.
It's a perfect fit and easy replacement. Like another reviewer mentioned, the plastic spline shaft on ours cracked and, thankfully, the replacement is metal. Thank you, Etrailer.
Thank you for having the part, but also thank you for the exceptional customer service. We will look to etrailer for future needs.
Quick shipment. Perfect replacement with easy instructions provided by etrailer.
Ordered this motor and it fixed my problem. It also showed up when expected. I also found the person I spoke to on the phone to be knowledgeable, professional and very courteous. I will use e-trailer in the future for any parts I may need.
