I saw A.O.Smith? brand blower motors, but I didnโt see one for the Coleman ac.
I think they make really good hot water heaters. I had one last a, long time.
Hi, this may help,
The AO Smith brand was used in the Domeitic AC's or at least on the older Brisk Air units. I have not had one fail yet on the Brisk Air II so I do not know if they stuck with them.
Not sure if you knew, Coleman-Mach has a standard 2-year part and labor warranty.
https://coleman-mach.com/service-support/warranty/You said two seasons; I didn't know when the installation dates. There may be some warranty left on it. They may make you take it to a service center to pay for the warranty.
On the motor issues, by chance, while you are in AZ now, did the camper come back northeast into freezing temps since it was installed? Or go to north AZ where it does snow? I know some of the Dometics that live in the eastern winter states have an issue with the motor rotor getting corroded to the stator over the winter/springtime thaw. The motor sweats from the fast-rising spring temp on a frozen motor, condensation starts inside the motor, and it can lock up the motor in the worst case. This issue comes in different levels of binding, but it can give symptoms as you are stating. That said, this may not be the issue if your camper never went through a freeze/thaw cycle.
The compressor can sometimes have big and little capacitors on the compressor, with one being a hard start capacitor. The fan normally only has one capacitor, which has less start-up surge. There are ways to test the capacitor, some digital multimeters have a test on them, and the older analog meters can tell if the capacity is dead.
Heads up, when you get a new motor, which may be a different brand and model than the one you had, check the label for the required capacitor size; not all AC fan motors use the same size. You might have to change the capacitor to work correctly with the new motor as the size is different.
Hope this helps
