Take some WD 40 and spray a liberal amount on the shaft where it enters the motor and spin it a few times by hand (unit off) and then try it again. Do this several times over a few days if it does it again. This will usually resolve this, but if not you need a new motor OR perhaps a hard start kit from Dometic. About $25 or so and not hard to install if you are somewhat handy with tools. Hope that proves helpful here. Please get back to me again if we need to dig deeper into this as all followups are included in our fee.

Just checking back in to see if you were able to get this resolved or so you still need some additional input from me here?
