Working on an old frigidaire SxS, customers returned home to a non functioning old style ice maker. Supply cord in freezer shocks me, can see arcing in connecting plug. The frezer door has 2door switches, one for freezer light & the other I surmise for the ice auger. The rear of unit has 3 water valves I would like to trace wiring out of courousity & also know how they are plumbed. I also would like to know as much info that I can find. This is my way of educating myself, do not have the luxury of attending traing schools. Yours help is always highly appreciated. Patricio
