How to Replace an MA-ND4 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.

    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


  5. 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.


  6. 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,

  7. 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
