Older Kenmore gas cooktops split into two ignition styles depending on age — standing-pilot units that stay lit continuously, and later electronic-ignition units that spark on demand — and the two are diagnosed differently, so confirming which type is installed is the first step before assuming a problem.

Touch controls that stop responding on a Kenmore electric cooktop are more than an inconvenience — in some failure patterns, they’re a real safety concern.

The wrong cleaning routine is one of the fastest ways to shorten the life of a Kenmore smooth-top electric cooktop’s surface and controls.

Kenmore’s standalone electric cooktops from this era are mechanically simple compared to current induction cooktops — no networked electronics, just burner elements, a switch assembly, and (on smoothtop units) an infinite-switch control. Problems are usually isolated to a single burner circuit rather than the whole unit.
