I am an electronic tech, although not experienced with induction cooktop appliances. I am seeking to repair the above item and have performed some troubleshooting on this item. The power light comes on, the fan starts up, but the cooking light does not come on when a pan is placed on the cooktop. The fuse is not blown and the full wave bridge rectifier is good. I have tested many of the circuit board parts and they all test good. Can you give me a clue where to go from here? Is it possibly in the sensing circuitry somewhere?
