What E33 means on a Kenmore range

The E33 error code on a Kenmore range indicates that the cooktop control board has detected a fault condition within one of the cooking zone pairs. Modern inductive and radiant cooktops often group heating elements into paired zones, and the control system continuously monitors these zones for proper electrical behavior. When the control board detects an anomaly, such as an unexpected signal, a failed component, or a communication breakdown between the surface elements and the control circuitry, it triggers E33 to alert the user and halt normal operation.

The fault most commonly originates in the surface element switch, the element itself, or the wiring harness connecting the zone pair to the main cooktop control board. Loose terminals, heat-damaged insulation, or failed heating coils can all send irregular signals back to the control board, causing this error. In some cases, moisture intrusion from boilover events can cause temporary shorts or resistance shifts in the affected zone's circuitry.

Because this error is flagged by the cooktop control board rather than a standalone component, diagnosing it requires isolating which zone pair is involved and then checking the associated switches, elements, and wiring connections. A reset using the STOP button or a full power cycle will clear the display temporarily. However, if the underlying fault is still present, the error will return. Persistent E33 faults typically require hands-on inspection and likely component replacement to resolve permanently.

Common causes of E33

  1. 01

    Faulty Surface Element Switch

    Part replacement

    The switch controlling the affected cooking zone pair can fail internally, sending incorrect signals to the cooktop control board. A failed switch is one of the most frequent triggers for zone-related fault codes.

  2. 02

    Damaged or Failed Heating Element

    Part replacement

    A burned-out or shorted surface element in the flagged zone pair can cause the control board to detect an out-of-range condition. Visually inspecting the element for blistering or breaks can help identify this cause.

  3. 03

    Loose or Damaged Wiring Connections

    Wiring / connection

    Wiring harness terminals connecting the zone pair components to the control board can loosen or sustain heat damage over time, producing intermittent faults. Inspecting connectors for corrosion, melting, or poor seating is an important diagnostic step.

  4. 04

    Moisture Intrusion from Boilover

    Wiring / connection

    Liquid spilling into the cooktop area can temporarily short connections or alter resistance in the zone circuitry, triggering the fault. If the error appeared after a significant spill, allowing the cooktop to dry fully before re-powering may resolve it.

  5. 05

    Cooktop Control Board Failure

    Part replacement

    If all zone components and wiring check out correctly, the cooktop control board itself may have failed and is misreporting a fault. This is less common but is the likely cause when no other faults are found.

Frequently asked questions about E33

What does E33 mean on a Kenmore range?
E33 on a Kenmore range means the cooktop control board has detected a fault condition associated with one of the cooking zone pairs. The control system monitors the heating zones continuously, and this code is triggered when something in the affected zone's electrical circuit falls outside expected parameters. It can be caused by a failed switch, a damaged heating element, or a wiring issue in that zone pair.
Will resetting the range clear the E33 error?
Pressing the STOP button or cutting power to the range can clear the E33 code from the display temporarily. However, if the underlying fault in the cooktop zone pair has not been corrected, the error will return once the range is used again. A reset is a useful first step for ruling out a one-time glitch, but a recurring E33 requires component-level diagnosis.
Is it safe to use my Kenmore range while E33 is displayed?
It is not recommended to continue using the range while the E33 error is active. The code indicates a fault in a cooking zone pair, which means that zone may not function correctly or safely. Using the range with an unresolved electrical fault in the cooktop circuitry carries a risk of improper heating behavior. It is best to stop using the affected zone and have the appliance inspected.
How much does it cost to fix a Kenmore range E33 error?
Repair costs for an E33 error depend on which component has failed. Replacing a surface element switch or a heating element typically runs in the range of $100 to $250 including parts and labor. If the cooktop control board needs replacement, costs can range from $200 to $400 or more depending on the specific model. A service call fee is usually added on top of parts and repair labor.
Can I diagnose the E33 error myself, or do I need a technician?
A knowledgeable DIYer can perform basic checks such as inspecting wiring connections for looseness or visible damage and checking for signs of a burned-out surface element. However, testing switches and control board signals typically requires a multimeter and some familiarity with appliance electrical systems. Because the cooktop involves line voltage components, those who are not comfortable working with electrical systems should contact a qualified technician. If the error persists after a reset, calling 1-800-4-MY-HOME is the recommended next step.
