As far as heating it up with a battery goes I am afraid that I may short the windings by burning away the laminate. At least I had adjusted it before it froze up and being new I fear that the only way that it could freeze up was that it was somehow overheated and the insulation that melted is holding it in place. As long as it isn't shorted I am ok and I have the spec sheet resistance values.

Can't you just lightly warm it up with a hair drier or heat gun wafted around the area or something so it's less likely to harm a winding trying to use it as a heating element?
