I own a 1984, Modern Maid Downdraft Cooktop, model #KET-570. The switch for the exhaust fan is bad. It is a rotary switch, meaning it has a knob that turns. The switch is obsolete but it was produced by Maytag and GE as well as Modern Maid. I am hopeing someone has one that they can sell me. Here are the specs:
Modern Maid part #74-03-104 Maytag Part #0042048 GE part #GEHWB24X5191 The printing on the back says the swith is rated at 10 amps and 120 volts. It also says 1/2 hp.
I hope someone out there has one they can part with. Thanks...
