Error code 30
Appliance Cooktop
Quick answer

Code 30 points to improper supply voltage (high) or an internal wiring failure; the manual brings in an electrician for the voltage check.

Model compatibility

Kenmore reuses codes across series and model years, so 30 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

30 reports an improper high-voltage supply or an internal wiring failure.

Details

  • Display: 30
  • Meaning: the supply voltage is too high, or wiring inside the cooktop has failed.
  • Applies to: Kenmore 790 induction models.

Action plan

Power is disconnected, then the supply wiring is examined and an electrician measures the voltage at the supply. A normal reading with sound connections shifts suspicion to the filter control board or the main power control board, a call for a technician.
