Electrical "buzz" from my FW
I have had my FW since the late 1970's. Lately, when I touch the throat plate or hand wheel (both silver colored metal) I've gotten a slight "buzz." Now it seems to be affecting the bed extension, as well. Any recommendations on how to fix this problem? The plug is the original 2 prong. DH is fairly OK in the workshop. Any help is appreciated. Thanks!
