Take off the screw knob at the top left of the machine (the pressure foot tension control). Take the face plate off. Spray WD 40 lightly on the parts where the pressure foot rod is supported by the cast iron sewing machine frame. Gently heat it with a hair dryer. Stop every few minutes to try the foot lever. Once you get it heated up, spray it again with WD 40 on the rod. It should come loose.

Don't force it. Heat it and gently try rocking it up and down if it will move at all. New ones can be had but you should be able to keep yours.
