Just What We Were Looking For
Posted by Raymond L Turgeon on 20th Mar 2019
Our HVAC company wanted to replace the entire damper because they claimed the damper was no longer available. That may be true but this replacement option was easy to install and did the trick.

Easy installation
Posted by Pete on 12th Jan 2018
Previous motor failed after 18 years. HVAC company quoted me $360 plus installation - went on web and found this one for $70. Fast delivery and installation took less than five minutes. I will be ordering another one as a spare since I have two more zones using similar age damper motors. Thanks ewcestore!

Still a DIYers Dream!
Posted by Unknown on 5th Dec 2017
My 2nd sub zone motor in attic went bad 2 years after the first one. I figured it was not far behind as they do have finite life. One lasted 12 and the other 14 years. Used this order to replaced a 2nd tired MA-ND3 which was in it's 14th year. Very easy to replace and test. Like another person who posted feedback, my lights were cycling red/green but the damper was not moving. Friends of mine have paid 300 dollars or more for this 15 minute job. Thank you EWC Store!

Easy Replacement for DIYer

Used to replace 2 15 year old damper motors. Took less than 20 minutes to install both. Easily saved myself hundreds of dollars. Fast shipping and quality products. Couldn't be happier.

Saved me $hundreds
Posted by Wendy on 3rd Sep 2015
After watching your YouTube video on how to install a new damper motor, I realized that although the red and green lights on my MA-ND3 were lighting appropriately, the motor was not working. Thanks for offering this product online and for the instructional video. You saved me hundreds of dollars because I didn't have to hire a professional. Very fast shipment and easy installation, too.
Thanks!
Wendy
