We heard a loud pop that came from the cooktop itself not the breakers, I have checked the breakers in the back of the house and all is ok. I disconnected the glass cooktop and opened it. I have checked the heater eletemts and all six are in tack, nothing is broken. I found that the indicator light are black in color inside, burnt like. I have a photo but dont think I can post one here. Now the burners dont come on neither the indicator light for none of the burners. If I change this indicator liights, will that fix the issue or the burners can work without those lights?
ANSWER Hi Manual. No, the light (240 vac) does not control the burner operations. The pop indicates a shorted switch or a wire or terminal shorted to ground. You really need to unplug the unit and use a volt meter to see if you have the proper 240 vac supply to the unit outlet. If so then you need to see if where the unit supply cord terminal block is intact and all connections are tight. Then use the wiring diagram supplied with the unit to see what the first switch L-1 (black supply wire) and the L-2 (red supply wire) is fed from. In a cook top it is a very tight wiring area that if a switch shaft nut is off and the switch is loose in the cabinet then it will create this issue. A shorted wire to chassis will leave a burnt black spot and create a blown hole (easy to spot). Remember that the indicator light is also as well 240 vac and the black spot is not necessarily a issue. Thank You.
