Error code3
ApplianceCooktop
3 on the display points to the Up key of the left front element. You will meet it on a Kenmore induction cooktop with a model number that starts 790.
Who does what
Pull the plug or flip the breaker for the cooktop. From that point a technician follows the manual: cable and connection testing on the wire harness, then a new touch control board on the left side if those connections check out.

Code 2: the Down key at the same left front element
Model compatibility: Kenmore reuses codes across series and model years, so 3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
