etrailer is great, no issues. Switch by fantastic fan, not so much. This switch should have lasted years not months. I hope the the replacement switch from etrailer lasts longer than the factory’s.

Well here is an update for our switch. So far so good. Haven’t had an issue and switch still working. Fingers crossed for another year.

This was delivered on time and it replaced the 30-year old switch perfectly!! My class B is 30 years old and it is a relief I can find parts to keep it going in tip-top shape. etrailer has been a terrific resource for that over the years. Thanks!! :-)

A year later, my replacement switch has worked just great. These older van gems often need updates here and there. This product kept me from having to replace the entire fantastic fan. It works just as one wants it to and was easy to replace. Im still very pleased. Thanks etrailer!

This didn't work for my Fantastic vent fan. I don't know what model number of fan I have, but my RV is a 2007 and the Fantastic Fan has/had a rain sensor control system that didn't work. I thought that this 3 speed controller would work, but one lead goes to a PC board and I don't know where to locate that lead to my PC board, which is probably why my fan doesn't work. The switch was fine, just didn't work for my fan.

Thanks for your reply. Unfortunately, I cannot find what model fan you have either. The replacement switch you bought just changes the speed of the fan, so if the fan is not working you may need to replace the whole unit. This is the fan that works with the replacement switch:

The product was great, but didnt work for my application. I kept it and may need to use it the future.

so glad has the parts I need especially the hard to find older parts. Will continue to to look to when I need parts. Plus it doesn't take weeks waiting.


The item came in when expected and in perfect condition. The only problem is I ordered the wrong one.


Good replacement for an old fantastic f an.


Replacement switch works great and is an exact match.


It’s so nice to have my new fantastic vent fan switch in and the fan working once again. It’s a simple five minute replacement. Thanks again to etrailer for a quick ship and a reasonable product price.


Bought a replace switch through [online vendor] and it stopped working within a month. Replaced it with this switch a year ago and it is still running my fan!


Great service!


perfect for my project / repair


Replaced switch in a 25 year old fantastic fan. Perfect fit, form and function. Easy installation.


My Fantastic vent fan model 3300 quite working, the fan motor worked with a set of jumper wires so Thought the problem might be the 3 way switch. After I received the new switch from etrailer it was a quick and easy job installing it. The fan now works like new. Finding the switch, ordering it and a quick delivery made it an easy fix. Thanks etrailer.

Still just like new!

Exact fit and function replacement for the original 3-speed switch for our 6 y/o Fantastic fan vent. Works like new.

Still working like new.
David - 07/23/2021


Had a single speed vent fan. I wanted to upgrade to a multi speed fan without having to change out the entire fan assembly. This switch was easy to install and works great. Saved money and time.

Fan switch is still working great after one year. Glad I purchased this.
Joy C - 08/24/2021


Worked great in replacement of my 05 fans. Shipping was moved up on order and received it a full week ahead of time.


Same as original. Got my fan back up and running.


I haven’t installed them yet. I have to straighten out all the bent metal that got mangled during shipping. A flimsy bag was not enough protection

I will have our customer service team reach out to you.

Works great and was exactly what we nee ded


Ordered 2 each replacement Fantastic Fan vent lids, lift crank assemblies and switches. etrailer had best pricing based on my internet search.

Items arrived quickly and were well packaged. I was pleased to discover that the replacement lids included the hinges. Changing out the lids was as simple as removing 4 screws from each old vent lid, fitting replacement lids, and reinstalling the old screws. Lift cranks and switches were exact replacements and also very easily installed.

I highly recommend etrailer for providing the exact replacement parts at best prices, and with speedy delivery!


I ordered this fan switch and it is a direct replacement for one that I had replaced a number of years ago. I was pleased with the service and the delivery in a few days! I will remember if I need to replace other items on my trailer!


this order has been delivered very fast. It works as expected and solves the problem. The Fan-Tastic roof vent is 7 years old but the Replacement 3-Speed Switch fits 100%. Unfortunately the Thermostat doesn't work either so I had to bridge it to get the fan working.


Great service was ordered and shipped the same. Had to return one item, which was easy to do.
