Hotpoint oven does not light up RGB790. - Hotpoint RGB745 Gas Kitchen Range

Question edited for clarity and toss in a load of CAPS!

It is a gas appliance and must only be worked on by a gas certified technician. It is likely to be the igniter to the oven, or more likely the Thermocouple safety device.

There is likely some kind of gas line blockage or valve problem. This is not a do-it-yourself fix. Call a repair person.

Is there any sign of life? Does the oven light come on or does the clock work? Just for kicks, go and reset the breaker - it should be a double breaker for a 220V appliance - sometimes half will throw and still leave 110v that will run the light / clock.

CHECK OVEN IGNITOR, IF IT IS GAS.

it is normal for the grill electrode to spark as well when lighting main oven - i assume you don't mean that the grill lights - just sparks

sounds like abad oven ignitor issue, repalce hte ignitor nad it should light everytime

the light only indicates that the oven elements are on.A blinking light i would have checked out for a short

The problem is almost certainly on the control panel, which we repair nationwide for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This often can affect the exhaust fan operation, too. The lights and fan can be inopoerable or stuck on.
