It does sound like you have water intrusion and that is causing the
problem. Most likely it has been happening for a long time, and has been
with the lubricant and emulsified - this can freeze up very easily. A
temporary cure could be some form of heating (use the resistance heater cable
used to keep gutters free of ice) but that will take power (117v) to
operate. Removing and cleaning it up is the correct solution.
Kurt's web site is a good reference for disassembly, cleaning and sealing
of small prop pitch motors.
The photo below is one of the keys to sealing the gear assembly. The seal
must be pliable, intact and lubricated. Not shown in Kurt's photo's is
any form of rain shield or "umbrella" which I use to further divert water
away from the spline seal.

I seem to be having some problems with my small prop pitch rotor freezing
When the temperature is below freezing. I'm assuming it's a two part
First, water must be getting in somehow.
Second, the water freezes when its cold.
My rotor installation looks like the fifth picture at
So, first, how do I manage to reduce water ingress?
Second, how do I manage to heat the rotor? I don't have 120v at the tower
And it is about 400 feet from the house.
