The E30DF74GPS is an Icon pro-style dual-fuel range. Its heavy oven door puts load on the hinges, and a door that does not close evenly lets heat escape and slows preheat. We check the hinges and gasket of an E30DF74GPS with slow preheat before the elements.

The E30GF74HPS is an Icon pro-style gas range. Bake and broil complaints on it are diagnosed separately, since broiling uses its own heat source. On an E30GF74HPS that bakes but will not broil, the broil burner’s ignition is checked.

The E36DF76GPS is the 36-inch Icon dual-fuel range. Its spark module feeds every burner igniter, so one module failure can stop all burners from sparking. If every burner of an E36DF76GPS stops clicking at once, the spark module is tested before individual igniters.

The E36GF76HPS is the 36-inch Icon gas range. Its wide oven uses a strong igniter and large burner; slow ignition shows first as a longer preheat. We time preheat on an E36GF76HPS as part of any heating complaint.

The EI30EF35JS is an IQ-Touch electric freestanding range with a published wiring diagram. With the diagram, element and relay circuits are traced directly rather than guessed. An EI30EF35JS that shows F30 after cleaning may have a sensor connector disturbed at the back of the oven.

The EI30GF35JS uses the ES 1030/1031 electronic oven control, according to its service data sheet. That sheet lists the control’s tests, which we run before replacing the control for any F-code. A gas EI30GF35JS that lights but will not hold temperature is checked at the sensor and then the igniter.

The EI30DS55JS is an IQ-Touch dual-fuel slide-in: gas burners on top, electric oven below. Its oven codes follow Electrolux’s F-code list, while burner problems do not produce codes. When an EI30DS55JS burner will not light, we check the cap, the igniter and the spark module in that order.

The EI30IF40LS is an Electrolux freestanding induction range. A cooling fan runs while zones are on and after, which some owners mistake for a problem. Supply-voltage codes on an EI30IF40LS point at the 240-volt circuit; both breaker halves and the terminal block are checked.

The EW30GS75KS is a K-generation Wave-Touch gas slide-in. Its oven relies on a glow-bar igniter; a bar that glows but never lights the burner is too weak to open the valve. We measure igniter current draw on an EW30GS75KS rather than judging it by the glow.

The EW30DS75KS is a K-generation Wave-Touch dual-fuel slide-in. Its convection oven has an element behind the fan cover; if convection bake runs cool, that element is tested. On an EW30DS75KS, burner and oven repairs are separate paths, so we note exactly which part of the range misbehaves.
