How to Replace an MA-ND4 / MA-ND5 Motor (04:40)
The current version of power open / power closed motor used on our dampers is the MA-ND4. The previous two motors, the MA-ND3 and MA-ND3B are similar in design and the same instructions apply. The replacement is ordered from an EWC Controls distributor as an "MRK" (motor replacement kit). The kit contains an MA-ND4 motor as well as brackets permitting replacement of most of our older, obsolete power open / power closed motors.

  1. Perfect! 5 Star Review

    Posted by on 6th Aug 2015

    We had two actuators out which eventually killed our outside unit. When the unit died we replaced it, but did not replace the actuator motors. We couldn't find them locally. Without functional actuators the system just couldn't keep up. We finally found the right actuator motors on EWCEstore and had them shipped overnight. They were exactly what we needed! They took about 15 minutes each to install. Our house is now habitable. Customer service was awesome, as well. - Thank you so much!

  3. It's magic! 5 Star Review

    Posted by on 20th May 2015

    My old damper motor started working again the moment the kit arrived and I found the right wrench. I'll keep the replacement part, just in case. Really fast shipping BTW! And the Youtube installation video is excellent.

    I was very satisfied with this damper motor. It was delivered in a timely manner and was easy to install. Thank you for your service


  6. Just what I needed 5 Star Review

    Posted by on 25th Aug 2014

    Glad I could order this replacement through. Saved hundreds $$$. Took me 15 minutes to replace the motor. Was an exact fit. No issues. Ordered a second one for my AC system once I was sure I had the right part.


  7. Easy to install even for a novice 5 Star Review

    Posted by on 28th May 2014

    I am not handy. I am just not. I own standard tools, but I can honestly barely use them. They serve more as ornamentation than for function. I had a MA-ND3 fail, sort of obviously. The lights were working, but no motion was happening. The motor was obviously failed.

    I watched this video

    https://www.youtube.com/watch?v=SjvW7fCj-2E

    It literally took me 15 minutes to replace the motor, where 10 of those minutes were caused by poor lighting around the motor. Once I had a flashlight all was solved.

    It couldn't have gone any easier or quicker.

    Problem solved.

    Cheers,

  8. thanks! saved me a TON of money! 5 Star Review

    Posted by on 11th Apr 2014

    My damper motor (MA-ND3) went out (was stuck in the open position) in a multi zone system and caused the upstairs to freeze while the downstairs remained warm. I confirmed it was getting the 24vac from the control board but just wasn't turning.

    I call the old air company that I used in the past for "the big jobs". they quoted $758 bucks to replace the damper motor! and that included a "loyalty discount" of 10% and free labor! Can't believe they had the nads to use the words "loyalty" and "seven hundred and fifty eight dollars" in same sentence.

    I pulled the old ... "...uh... i'll get back to you" and found stores.ewcestore.com and the Motor Replacement Kit for $70 and thanked the Lord.

    I splurged on the shipping (since I felt that I was saving 700 bucks), got the MRK with a quickness and replaced it in about 10 minutes.

    Damper is opening and closing with ease now. Thanks ECW Store!
    Frank
