Kenmore cooktops: series and lineup
Kenmore cooktops follow the same decode-the-prefix pattern as Kenmore ranges, because Frigidaire built nearly all of them. Electric cooktops in the 790 prefix block include the 790.42739403, 790.45103410, 790.42732401, 790.43043401, and 790.42743401. Gas cooktops in the same block include the Kenmore Elite 790.33233400 and the base 790.32094400, and at the top of the lineup, the Kenmore Pro 790.30503601 is a gas cooktop built to the same professional-styled standard as the Kenmore Pro range. One notable exception to the Frigidaire pattern is the 911.42676991 electric cooktop, which carries the 911 prefix tied to Roper — a Whirlpool subsidiary — meaning its control and heating-element architecture follows Whirlpool’s design rather than Frigidaire’s, even though it wears the same Kenmore badge as the 790-series units around it. That single exception is exactly why we confirm the full model number on every kenmore cooktops call rather than assume every Kenmore cooktop shares one parts catalog. You can browse the units we service in our model directory.
Technologies and features
Kenmore cooktops built on the dominant Frigidaire 790 platform pair sealed gas burners or a smoothtop electric surface with the same control-panel styling used across the Kenmore cooking lineup, stepping up to continuous cast-iron-style grates and higher-output burners on the Kenmore Elite 790.33233400 and Kenmore Pro 790.30503601. The Roper-built 911.42676991 electric cooktop instead runs Whirlpool-family radiant-element and infinite-switch control logic under its own Kenmore control panel. Because a cooktop has no oven cavity, it also has no RTD probe or self-clean door latch to fail, which narrows the parts list compared with a range: on a Frigidaire-built gas 790-series cooktop, the parts that wear are the sealed burners, the spark-ignition module, and the burner control valves; on an electric 790-series smoothtop, the radiant elements and their infinite switches; and on the Roper-built 911.42676991, the same radiant-element and switch layout under Whirlpool’s wiring convention.
Common issues and maintenance
Kenmore does not publish a confirmed error-code display specific to standalone cooktops, so a kenmore cooktops call is diagnosed by symptom and by confirming which OEM built the unit. A gas burner that will not ignite is most often moisture trapped under the burner cap, a clogged burner port, or a weak spark-ignition module — check for moisture and a clean port before assuming the igniter has failed. A burner that clicks continuously after lighting usually means a stuck-open igniter switch or a wet control knob. On an electric smoothtop, an element not heating points to a failed radiant element or its infinite switch, while a cracked or scratched cooktop surface is a physical-damage concern rather than an electrical problem and is typically a surface replacement. An unresponsive control panel or knob is frequently a membrane-switch failure behind the control face. Routine care helps across every platform: keep burner caps and ports clean and dry, avoid dragging heavy cookware across a smoothtop surface, and clean spills before they bake onto the glass or drip into a gas burner base. It is also worth noting that a cooktop paired with a separate wall oven is diagnosed independently from that oven — a cooktop ignition or element failure has nothing to do with the oven cavity’s RTD sensor or control board even when both share the same kitchen wall, so describing exactly which appliance is misbehaving saves a wasted diagnostic step. A homeowner can safely check for moisture under a gas burner cap, confirm nothing metallic or misshapen is blocking an electric element from seating flush, and wipe the control panel dry before assuming a genuine component has failed.

When to call for repair
Sealed gas burners and spark-ignition modules, radiant elements and infinite switches, and control-panel membrane switches are best handled by experienced technicians who confirm whether your cooktop is the dominant Frigidaire-built 790 platform or the Roper-built 911.42676991 before ordering parts. As an independent, third-party repair service we are not affiliated with Kenmore, Sears, or Transformco, and our specialist technicians back every visit with a 30-day labor warranty on the workmanship. Note the exact symptom and whether your cooktop is gas or electric, and your full model number, when you book. A clear quote is given before work begins and the total depends on the diagnosis; pricing starts from a trip-and-diagnostic fee, and we never quote a fixed repair price sight unseen.
