Video Transcript for Fantastic Vent RV Vents and Fans FVK6050-80 Review

Today we're going to be taking a look at a replacement lift motor. This replaces a damaged auto lift motor in a Fan-Tastic vent B series roof vent with powered lift arms. You'll notice that the housing is off white in color. It's going to include one 7 RPM replacement auto lift motor. The motor actually has a label on it. It's going to indicate that it is 7 RPM and on the other side it's going to indicate that it is a 12 volt DC motor.

It's going to feature a two wire design. You're going to have a red wire and a white wire. They have the connectors on them, which allows for easy and quick wire connections. The housing does feature the built in mounting tabs and it's going to come with two mounting screws for installation. The screw heads are painted to actually match the color of the housing to give it that clean finished look. Here I have a black knob located right here.

Now this knob needs to be pushed all the way down for auto operation. As you can see there, it has a large indicator sticker on there. Then when you want to operate the unit manually, you just pull out on the handle and you can easily do that for manual operation. When you're ready to use it in auto mode, you just push it back down and it's ready to go. The mount holes on this unit, again there's going to be two mount holes on it.

I did take a measurement of the distance we have between those mount holes going center on center at a straight line measurement and I got a measurement of 3 and 3/8 on an inch. That's going to do it for today's look at the replacement 7 RPM auto lift motor.

Use this 7-rpm auto-lift motor to replace the damaged one in a Fan-Tastic Vent B Series roof vent with a powered lift arm.


I got exactly what I expected. The packaging was the right size and not overdone, yet product properly protected. Product looks exactly as it does in the pictures. I had to wait a very long time for it (5+ weeks), nevertheless I'm still happy with the product.

Its been working as expected. No issues at all. Very happy that this was is a quality product.

Fits perfectly and installed easily. The video could cover installation as well even though it's very easy. My only concern was lining up the lift motor drive "axle" with the fan.


Fantastic group of people to work with!
fit, exact replacement and fast shipping.
Excellent work everyone!

Perfect fit easy to install fast delivery happy camper

Its not stopped working 2nd time out

This was my first time dealing with etrailer, and it was wonderful. This company is one of the few I have encountered during the past few years that takes the concept of 'customer service' seriously. Info arrived via email reply ASAP, ordering items was made easy for me, delivery occurred within a few days, and it took me altogether 2 minutes to install the replacement and enjoy my Fantastic Fan again. Also ordered handles for my bathroom and shower fans (they were broken for years, I live full time in my Airstream) and feel like I just bought my aluminum 'tiny house'. Companies such as etrailer make living like this easy.
Thank you, everyone at etrailer, from the bottom of my heart for caring for your customers :-) I am looking forward to the next part breaking with a lot less nervousness than before, now that I know etrailer :-)

Very well. No problems. Love etrailer and the people one can talk to. Excellent service, excellent product, absolutely reliable. Thank you, etrailer :-

Perfect fit. Exact replacement. Stopped working within 6 months, however.


Packed well and prompt delivery. Will certainly use again.

As expected, I needed to trim the bottom cover and add spacer & longer screw to connect with lid arm of 15 year old Fantastic Fan. Used original handle as it fit better in opening. Will fill in corner with sheet plastic.

Great. Only had to trim the older style enclosure to fit the new motor. Working fine several tomes a week. Thanks for prompt service

Works great, now


This was a replacement for the exhaust fan in my shower in my motorhome. It has worked great since it was replaced.


Great service, Just what I need, 5 star, would order again

Still working great, use it another. Thank you

It worked as described but that did not fix my problem because I ordered the wrong part.


Exact replacement, works great!


A perfect OEM replacement for my fantastic fan motor, the lift capability having failex because of gear stripping. All is right in the world again.

As a followup. The fan works as expected.

Recv'd part - all installed. And it works! :O


Not sure if there was any problem with the Replacement Lift Motor for Fan-Tastic Vent B Series Roof Vents with Powered Lifts, but after a few months it failed too. I believe the issue is the crank arm gears were worn and they don't seem to engage completely. So, it will fail after a period of time, my suggestion would be to replace the crank arm and the lift motor as a pair and it would probably last much longer. We ended up replacing with a complete insert upgrade that came with new motors and crank as part of the package. The new parts don't seem to disengage to open the lid manually, which seem to be a better system.


Great communication especially with today’s supply chain challenges. Will definitely order here again!


This replacement part installed as if it was in the factory down to the wires. Plug and play.


Product was the best price I could find and the delivery was on time. I am traveling around the country and needed the motor prior to leaving the sight I was in, in one week, got the motor two days prior to departure. The only problem was created by the labels applied to the package by the UPS and USPS. The labels were not readable by the delivery man so it went back to the local PO. I had to go to the tracking site in order to see that several calls needed to be made to get things worked out.

Still working fine

This is a new style motor drive. I doesn't fit the same as the old style motor drive and doesn't fit an older style fantastic vent. The shaft is not long enough to stay in contact with the splined shaft of the opener mechanism. When the motor was running had to press my thumb on the handle to apply enough pressure for the shafts to stay in contact to open or close the vent. If you tried to use the handle in the manual position you could not open or close the vent. Once in a while the motor would run on its own as there would be no pressure to stop it. This happened several times while driving down the road.


Quick and accurate information and delivery response was excellent. Associate was very through and knowledgeable and helpful.


The item arrived at quickly. I had called dometic who handles fan-tastic products for the correct part number. The item appeared to be an exact replacement. First issue, manual handle was too long. I had to replace it with the old knob. The other issue. The new case screw holes were slightly further apart. Had to remove the knob again and replace the new case with the old one and reattach the knob. The replacement part now has the vent fan operational.


Replaced the lid raising motors on two of my Fantastic Fans. Both are now functioning normally.

My only concern about this purchase was the labeling of the package. I am in a campground and for deliver, the site number must be listed in the address. I submitted the site number in my address but it did not make it to the package label. This required a call to your company to correct the error. This change was handled very well and then I received my package.


This replacement part was not an exact replacement for the original as the shape was slightly different, but it fit and works. The mounting holes fit and the shaft connector was the correct length.

The replacement motor continues to work without issue.
