How a Kenmore cooktop reports a fault
Kenmore cooktops are mostly Frigidaire-built (790-series), with some Roper-built (911-series) electric models. A cooktop with a digital touch control shares the same Electronic Oven Control “F” code family as the range and wall oven from the same builder; a basic mechanical-knob electric or gas cooktop has no display at all and is diagnosed entirely by symptom.
Digital-control cooktops (Frigidaire-built)
Where a Frigidaire-built cooktop carries a digital control, it can show the same Electronic Oven Control codes as a Frigidaire range: F10/F11 (control or keypad fault) and F30/F31 (temperature-probe fault on models with a probe).
Standard electric and gas cooktop symptoms
A burner or element that will not heat usually traces to a failed switch, a burned element, or a faulty relay on the control board. A gas burner that will not ignite usually traces to a clogged igniter or orifice, or moisture in the igniter. An unresponsive touch panel points at a membrane-switch failure or a blown control-board fuse.
What to check, and when to call
Clean the surface and confirm cookware is flat and correctly sized before suspecting a part. A recurring digital fault code, a burner that will not heat on any setting, or a gas burner that will not ignite needs an experienced, independent technician with the correct genuine OEM part matched to your cooktop’s actual builder; if you ever smell gas, ventilate and shut off the supply first.
