I parked my 10 footer at 135w a few weeks ago in preparation for snow. When I got back from vacation the dish would not move. I went out and looked at it today and the actuator is closed completely and i can hear the motor try to move when actuated but nothing. I tried pushing on the dish to help it but it still won't go. I have a few spare actuators that I will have to setup maybe next week.

The actuator is a Superjack and I haven't had any problems with it until now. Does anyone have any experience or tips on how to unjam one of these? I am hoping that I can fix it. I have a brand new actuator in the basement but it is a cheap model and would prefer not to use it.
