Thank you for your suggestions. The rotor is the 1048D. Abut 3 years old. The
pot resistance measurements do not vary with temperature. More likely
mechanical in the area of the motor interface to the ring. I allowed it to
stall for several minutes a couple of times, probably not a good idea, and
when it heated up enough it turned.

[TowerTalk] Preventing tic ring motor from freezingDate: Mon, 24 Nov 2008
Hi Not sure which model or revision you have but assume it's the older
aluminum box encased motor unit.The ring rotor is a basic electro/mechanical
unit and it's weak line is it's positioning " POT" there are two I call them
the black ones and the blue one's . The blue ones are the latter and less
susceptible to moisture invasion compared to the black ones, both are the weak
links in a EMF strike but that's another story. The " failure FREEZE "
indicates to me Moisture there are no relays in the unit only the "POT"remove
the wires from the in shack control box ( when it's frozen up ) #4 is CW #6 is
CCW and #5 is the wiperThe pots is 500 OHM so a simple wire wring out OHM
check between #4,#5,#6 will determine if it is in fact your thermal failure.

Other times it works perfectly. Maybe I got the tropical version :-). I don't
believe it is associated with water entering. It is sealed and this occurs even
when the WX has been dry for days. Carl says there is no grease inside. In any
case I was thinking of some type of heating strip used for gutters or similiar.
This poses the problem of thermostat and supply voltage problems. > It has
