Error code 30
Appliance Cooktop
Quick answer

Code 30 reports an improper power supply (high voltage) or internal wiring failure. The manual calls for an electrician to check the supply voltage.

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 means an improper power supply (high voltage) or an internal wiring failure.

Code 30 on the display

Thirty on a Kenmore induction cooktop is the code for an improper power supply (high voltage) or internal wiring failure. Models with a number beginning 790 use this list, and their codes carry no letter.

Manual steps in order

  1. Disconnect power.
  2. Check the power supply wiring.
  3. Have an electrician check the supply voltage.
  4. If the connections are good and the voltage is normal, the main power control board or filter control board is defective.

Replacing either board is technician work; the owner’s part ends at the supply wiring and the electrician’s voltage check.

Other codes to compare

  • Code 31: Power level failure, handled the same way.
  • Code 35: improper power supply voltage (low) or failed wiring connections; same family of faults.
