Error code 4
Appliance Cooktop
Quick answer

Code 4 identifies a defective On/Off key for the left front element. The fix in the manual is a left-side touch control board after checking connections.

Model compatibility

Kenmore reuses codes across series and model years, so 4 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
