Rebuild 53 thru 62 heater switches. I can replace the steel cable and outer shield. We also reseal the resistor and test for proper operation. Cost $100. Cam must be good in your switch. We will be servicing the cam in the future. Will sell switches outright as well, 58 to 62 $200., 56 and 57 $225. 53-55 $250. These are original switches.
