Answer to continue safely

Is it safe to keep using?

Maybe. Other zones without the E4 error can still be used safely. Do not attempt to use the zone displaying the fault, as it lacks proper temperature monitoring.

Can I reset the code?

Yes. A power cycle may temporarily clear the code if the sensor connection is intermittent, but the fault will likely return.

When to stop immediately?

Stop if you notice: Stop if the affected zone overheats or glows unusually bright before the E4 code appears., Do not continue if E4 appears on multiple zones simultaneously..

Symptoms You May Notice

E4 code on one specific zone

The error appears on a single cooking zone while other zones continue to operate normally.

Zone shuts off during heating

The heating element activates briefly but then shuts off and displays E4.

Error appears on power-up

The E4 code shows as soon as the cooktop is turned on, before any zone is selected.

Inconsistent zone temperature

The cooking zone overheats or underheats noticeably before the E4 code eventually appears.

Possible Causes

1

Failed NTC thermistor

The temperature sensor has degraded or failed completely, producing open-circuit or short-circuit readings.

Requires Professional
2

Damaged sensor wiring

The wire connecting the NTC sensor to the control board is broken, pinched, or has corroded connectors.

Requires Professional
3

Control board input fault

The analog input circuit on the control board that reads the sensor resistance has failed.

Requires Professional

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Power cycle the cooktop

    Turn off the breaker for two minutes and restore power to see if the E4 code clears.

    Note whether the code returns immediately or only after the zone heats up.

  2. 2

    Identify the affected zone

    Record which specific zone displays E4 so you can relay this to a service technician.

    Some models show a zone number alongside the error code on the display.

  3. 3

    Test other zones

    Try using each of the other cooking zones to confirm they operate normally.

    If multiple zones show E4, the control board is a more likely cause than individual sensors.

When to Call a Professional

Contact a qualified technician if:

  • The E4 error persists through multiple power cycles on the same zone.
  • The zone overheats significantly before the fault code triggers.
  • Multiple zones display E4, suggesting a control board issue rather than individual sensor failures.
