Question: Will this work with VenTech speed controller (input: 120V, max 15amp) to change the rotational speed?
Document: With the fan running, the flap is pushed toward the straight down position and a gap opens up. At first, the gap was small and not much air was moving. I thought that this motor would not work.After a couple of minutes of running, however, the fan picked up speed substantially, and then stayed that way. At that point, the flap was opening 1/2&#34; to 1.4&#34; and a good amount of air was moving.
For 10 minutes time and 2 basic tools, I have a smooth quiet fan like new again. Easy change. Thanks !
I chose this rating for speed that I received the product and quality of the shiping time. Good product overall bolted right in place of old one.
I have 3 bathrooms where the vent fan needed replacement. My husband and I are both retired. He is disabled. I needed a fan motor that I could change. I knew that I could not install a whole new fan. LOL! I looked for something that would be easy to change without cutting into the ceiling. I found it. My house was built in 1986 and the same fans have been in the house. I ordered the fan kit and I am really glad that I did.
Installed it today. Saved me a ton and a lot of unnecessary work. If your bathroom fan starts making noises, this is the ticket.
Perfect replacement for a 42 year old ceiling fan. I replaced two of them and they work great. Definitely get it.
I sent it back because I didn't want to file down one of the prongs to make it work since I was installing in a rental that required the two slim prongs.
Was able to replace my old bathroom fans with new insides and they work great now. Glad I was able to replace and now have to buy new ones. Saved me lots of money
Had a bathroom fan go out a long time ago in my apartment and had no idea what to do about it. Finally thought to look up one of these on here. Installed it pretty easily in about 20 minutes. I have no experience with any stuff like this. It seems to work just fine. No complaints.
Great product. I am glad I was able to make it work for me. I spent about a third of what the NuTone motor would have cost, so if I have to replace another motor, I would gladly order another one of these and modify it.
Answer: no
