This vintage Farberware Perfect Heat model 100 heat control and power cord unit will work with the company's vintage and some newer model electric skillets, frying pans, buffet cookers, griddles, woks, and other small appliances where the temperature control is not on the appliance itself. It's the earlier 1960s American made Bakelite model with non-polarized plug. It's been tested and works fine, with the white triangle indicator lighting up red when the desired temperature has been reached. The white numbers on the dial are have discoloration from age and use.
