Comments about Motor Replacement Kit:
The MA-ND5 is an upgrade actuator over the MA-ND3 that were origional equipment on my duct work. I'm very satified with the ease of installation and knowing I've purchased a newer /upgraded version damper motor at a terrific price, thanks again Pexsupply for a nice buying experience without any B/S
Bottom Line Yes, I would recommend this to a friend

Not mechanically inclined? No worries!
from Atlanta, GA
I'm reasonably good with pliers and a screwdriver, but I'm no engineer. I had no problem at all replacing the old motor on my damper. Just be sure you orient the damper position correctly before locking it down. The red/green lights to show closed/open are good.
from Blue Springs MO
Replacement for a 3 series motor, exact fit - easy instalation. Didn't need any of the brackets or screws. Con - did not include a damper position indicator, the old 3 series one did not adapt.
from New Freedom PA
The part ordered from Pex came very quickly, was packaged safely, and there were no problems at all with the order. I would definitely order from Pex Supply again. Great experience overall.
Works with Honeywell EnviraZone Panel
from Houston, TX
I replaced my Carrier WeatherMaker zone controller with a Honeywell EnviraZone panel. Those damper motors were relying on the Carrier zone controller to turn them on/off, so they kept running non-stop since they Honeywell doesn't work that way. They are also motor open/close (no springs). I replaced them with these damper motors and they work great with the Honeywell panel. They also allow the zone ON/OFF lights to work correctly on the Honeywell panel. A nice touch to also have the red and green LED lights on the motors to indicate if they are in the open or closed position. They installed right over the existing damper knob and I tightened them securely. They were easy to install and were fully adjustable for their open/close distance.
Great service from PEX, and great product fit for ND3 replacement. Ten mins to replace, and the new unit seems to have quite a few updates since the ND3.
Easy DIY Project
By DIY Enthusiast
from Denville, NJ
I ordered 2 MRK units to replace EWC Controls Inc. MA-ND3 damper motors that had stopped functioning. It took about 20 minutes to replace both units. You need only to disconnect three wires from the old units and then remove the old units from the damper per the accompanying instructions. The MRKs are then reattached in the same manner. Just make sure to label the wires so you hook them back up to the correct terminals. Also make sure when you attach the motor to the damper actuator that the damper and the actuator clamp are both oriented to the open position. This was one project that is as easy to accomplish as you think it should be.
Used to replace MA-ND3 damper motors in residential application. Easy installation and the directions were fairly easy to follow. Only gave 4 stars because they have only been installed for about 3 wks. We'll see if they perform for the long term.
I used these to replace the Carrier Comfortmaker actuators installed in my house in 1997. These actuators are working great! I had to reposition the old rear mount that was already in place on my dampers - but it all worked out in the end.
