A single 8 on the display is a key fault: the On/Off key of the left rear element is defective.
What the repair list says
Power goes off first. The wire harness cables and every connection along them are tested. If they all pass, the left-side touch control board is the part to replace.

Kenmore cooktop service near San Francisco
Our technicians test the harness and, when it is sound, move on to the touch control board. Ask for a visit at Kenmore cooktop repair or on (415) 825-6393, covering San Francisco and Bay Area homes. Note the model number and whether the left rear element reacts to touch at all.
Model compatibility: Kenmore reuses codes across series and model years, so 8 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
