Synchron 37944L replacement “yellow wire” left hand rotation for direct replacement of Ztech Buetler motorized damper applications. If your motor carries this part number, this will be the exact replacement motor for your application. Mounts with two screws. Note: Synchron Motor number 37944L has become very difficult to obtain due to a manufacturing shortage not expected to recover until late 2022. However, we offer two Belimo kits designed to replace the 37944L at about the same cost, which mount a far more robust Belimo commercial motor in the place of the old Synchron motor. Both Belimo kits carry a 5 year warranty and will far outperform the original motor. Use the BH Kit 2 (three wire upgrade https://www..com/dp/B08NRKZL3Q?ref=myi_title_dp) or TFB Kit 2 (uses the two original wires - message us via for more info on two wire version). From Retrozone, where dampers are our only business!

Worked
I ordered the first motor and it froze up after 2 days. Seller promptly sent me a new one and it’s been going strong for a month.

Perfect fit
It’s the exact same motor brand that was in my system. Quick and easy install, thank you.

Great replacement damper motor!
I used this to replace an old damper motor that had gone bad. My original motor was stamped with the following information (Cramer Company, 9739, P/N 61047, 1 RPM, 24V 60HZ), but it seemed that that motor had been discontinued. I found Retrozone and gave this motor a try and it worked perfectly!

Worked like a charm.
It took less than 5 min to install the part and restore my Split system HVAC back to normal operation. Now we are not Roasting upstairs and freezing down stairs. My wallet and wife are happy again.
