The E30IC80QSS shares its documents with the 36-inch model. A buzzing or humming pan on induction is normal at high power, especially with layered-base cookware. A zone that shuts down during long boils on an E30IC80QSS is usually overheat protection, and ventilation below the counter is checked.

The E36IC80ISS is an earlier Icon 36-inch induction cooktop. Codes that name one side of the cooktop usually point at that side’s generator board rather than the controls. We note which zones still work on an E36IC80ISS; that pattern narrows the board.

The EW30IC60LS is a 30-inch Wave-Touch induction cooktop sharing its guide with the 36-inch EW36IC60LS. Its cooling fan runs during and after cooking, which is normal. If the EW30IC60LS fan is silent and zones shut down early, the fan is tested.

The EW36IC60LS is the 36-inch Wave-Touch induction cooktop. Its wider glass puts more keys under spills, and a boil-over across the control strip can lock the cooktop until wiped. We clean and dry the control area of an EW36IC60LS before testing its touch board.
