What to do when Er shows on the rangeKind of codeSurface elements and induction
A radiant element, a coil or an induction zone did not heat the way the control expected, or ran hotter than it should. The pan, the switch behind the knob and the wiring to the element come first; on induction, the power board and the coil under the glass are checked next. A zone that will not switch off, or a crack in the glass, means the breaker goes off before anything else.
Usually leads toSurface element and glass top repair
Electric zones that stay cold, run too hot or will not switch off, and cracked or damaged glass on radiant and induction models.

Surface elements and induction on other makes
Gas range
Open flames on top and a gas-fired oven below, all fed by one supply line behind the range and lit by igniters rather than a match.
Dual-fuel range
Gas burners on top and an electric oven below, the combination most professional-style ranges use, needing both a gas line and a 240-volt circuit.
Induction range
A glass top that heats the pan itself through copper coils and power boards, over an electric oven, with electronics doing almost all the work.
