The top come on but the oven will not light any more

the preheat light wont go off on my oven, and its not really hot. my oven light is on as well ,how do I turn off the preheat light

change the thermostat and check.

The unit is working as it should. The top oven lights will only come on when the top oven control knob is turned on. The grill control does NOT turn the lights on. If you want to see what you are grilling, then you should turn the top oven control on to its first position. This works even if the grill is operating.

You need to replace top resistance in your oven

You can raise the top lid of the stove to light the pilot lights for the top burners.
The oven is controlled by a electric glowbar ignitor.
Make sure the cord is plugged into a electrical outlet.
If it is and the oven does not work the glowbar ignitor must be replaced.

if its a brand new unit (still in waranty) make the service call

could be a clock fault - try bypassing the auto function on clock.
otherwise, check the terminal block where mains is connected. these quite commonly burn out

need a new overn igniter...
