What Element Stuck on High means on your Kenmore cooktop (kenmore cooktop element stuck on high)
A kenmore cooktop element stuck on high problem means a burner does not cycle down when a lower setting is chosen, staying at full output instead. On a knob-controlled cooktop, a failed infinite switch that is not properly cycling power is the near-universal cause. On an electronic touch-control cooktop, a stuck relay or triac on the control board is the equivalent failure.

Symptoms
The signs below help confirm you are dealing with this condition rather than a different problem on your Kenmore cooktop. You may notice one of them or several together, and they can appear gradually or suddenly after a power event, a wash or cook cycle, a spill, or recent installation or service.
- The element glows at full brightness regardless of the setting chosen
- Food scorches or boils over because the burner will not step down
- Turning the element off entirely is the only way to stop the heat
- Other elements on the same cooktop cycle normally
Common causes
Several different problems can produce these symptoms. Working through the most likely causes in order separates a quick owner-level check from a problem that needs trained service and the correct Kenmore parts.
- Failed infinite switch (knob models) — the switch is stuck closed instead of cycling on and off to regulate heat
- Stuck relay or triac (electronic models) — the control board is not switching power to that element
- Welded switch contacts — a specific failure mode of an infinite switch after years of use
- Control board failure — less common, but possible on touch-control cooktops
Troubleshooting steps you can try
Work through these checks in order before calling for service. Stop wherever you are unsure, or where mains voltage, gas, a hot oven cavity, water, or a sealed component is involved, and hand the rest to a qualified technician.
- Turn the affected element off at the knob or touch control and confirm it fully stops heating.
- If the element cannot be turned off, or immediately restarts, disconnect power at the breaker until it can be serviced.
- Do not leave the cooktop unattended if an element cannot be controlled.
- Note which specific position is affected to help the technician target the right switch or relay.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the infinite switch, relay/triac (electronic models), and touch control board. The correct part for your Kenmore cooktop is matched from the model and serial number, and genuine OEM components are fitted through trusted parts suppliers rather than generic substitutes so performance, safety, and the appliance long working life are all protected. Confirming the failed part before ordering avoids replacing more than the problem actually requires.
