I agree, take the machine for a professional cleaning. The service may have a controller or know where you can get one. The machine plug is the hardest to find. You may be able to use a solid state controller, if it is not one of the pneumatic controllers. The solid state controller was $16.95 from Sew-Classic.Com. Wire can be purchased at a local hardware store by the foot. The plug for the machine is the hardest to find. Your service person may have one that will work. Good luck.
I just remembered, there is a shop in central Illinois, where my DGD got her machine. The owner's husband is a certified Bernina repairman. He fixes FWs also. The shop is Peace and Applique in Rochester, Illinois. You might try emailing them for information.
