KitchenAid KCED600G Glass Cooktop Repair

On a KCED600G, every cooking zone is driven by its own switch. That is why a single cold zone beside two working ones sends us to that zone’s switch, terminal block and wiring before we ever suspect the rest of the cooktop. It is also sold as KCED600GSS, and the repair approach is the same for both.
A glass-top cooktop of this age is usually dropped into a countertop cutout and has been through years of heavy pots and spills. The failure we meet most often is a switch that welded shut, so the zone glows at full heat whatever the knob says. We shut the circuit off at the breaker, test the switch with a meter, and replace only what the readings point to.
Every visit starts with a written price, and the work carries our 30-day workmanship warranty.
Turn the cooktop's breaker off and leave it off. A zone that ignores the knob almost always has a switch stuck closed, which means the element draws full power continuously. We confirm it with a meter and swap the switch.
We advise against it. Liquid can reach the hot elements through a crack, and the damage can spread with heat. Switch the cooktop off at the breaker until we have inspected the glass and quoted the repair in writing.
We check that zone's switch for continuity, then the terminal block and the element's resistance. Because each zone has its own circuit, this narrows the cause quickly without taking apart the working zones.
