Hi Dan, I had used the jack two times just a couple weeks before it "stuck" so I thought it couldn't be "seized". I just didn't think it had had enough time for that. I put a rag on the motor output shaft gear and grabbed it with a small pliers. It didn't take much force for it to loosen up. I then hooked up a 12 volt power supply to the motor and ran it a few minutes in each direction. It ran fairly smooth from the beginning and seemed OK. I put everything back together and ran the jack up and down enough to put normal loads on it and again, it ran fine without any unusual noise or vibration. There had to be some moisture down in the motor bottom bearing to cause it to "stick" so I suspect it's just a matter of time. But for now it looks like I am OK.
Thanks for clarifying. A good nudge could've been anything from the pliers you used to a pipe wrench and a breaker bar. :) I'll give the pliers a try next time I have problems, and I'm just a little annoyed with myself that I didn't give something like that a try before sending mine back.
