The E5 error code on a Kenmore induction cooktop indicates the supply voltage is outside the acceptable operating range. The cooktop requires a stable voltage supply to operate safely.
Causes
- Low supply voltage (voltage sag during high-demand periods)
- Loose or corroded wiring connection at the junction box
- Undersized electrical circuit for the cooktop
What To Do
- Check that the cooktop is on its own dedicated 240V circuit of the correct amperage (typically 40–50A for induction).
- Have an electrician inspect the wiring connections at the junction box.
- If voltage is confirmed correct, the cooktop’s internal voltage sensing circuit may be faulty.
