Hey Scott,
We don't have a replacement motor for a Coleman-Mach 48209-0650, unfortunately. I'm not finding it on other sites either, so I don't know that it's a replaceable part from Coleman-Mach. Because of that, it may be time to replace that unit. A replacement would require updating your system from a R410a refrigerant to an R32 system due to the new EPA regulations that started in 2025. These two refrigerants and their components are not compatible, so you'd need a new AC unit, distribution box, and thermostat. This is made easy with our Furrion Chill Cube RV AC System # FR27TD that includes all required components for a non-ducted system. If your system is ducted, you can use Furrion Chill Cube RV AC System # FR39TD which is the same otherwise.
What do you think happened to the motor on your 2023 Keystone Montana 3901RK? Are you prepping for a trip, maintaining, or winding down for the season?

The AC units are the Coleman Mach 15 Quiet efficient models. The full load amperage rating of these condenser/ evap motors is approximately 1 amp lower than the standard Coleman Mach motors, Hence the Efficiency nomenclature on these AC units. The motor on one of my units is starting to have some bearing noise at initial start up, but quiets down when the bearings warm up in the motor. I would like to have a spare Motor on hand for, if/When this motor gives up the ghost. I was hoping that E trailer would have a contact at Coleman so that we could get the correct part, or part#
