Do you have a model number located on a sticker around the front frame of the tub and can be seen if you open the door or remove the drawer below the door so that I can better assist you?

Perfect, thank you. This model has a very complex system with a DSI board (direct spark ignition board) which reads the gas valve coils and checks the resistance to make sure everything is good with the valve.

The first thing you want to do is remove the floor inside the oven and locate the spark tip. You may need to heat up the tip and bend it just slightly (careful not to crack the ceramic) so that the tip sparks just above one of the gas holes and is about 1/8" away from the burner at the tip. Over time the heat from the burner can cause the tip to warp a little and not be aligned properly so that when the metal heats up, it's no longer touching one of the flames coming from the burner which will tell the gas valve to stop sending gas for safety reasons.

Now if the spark tip has been correctly aligned and you still have problems, you have an issue with the gas valve or the DSI board. This board also serves other functions like sending out the actual spark to light all the burners as well as cuts out the gas if it doesn’t detect the flame has ignited. There are 3 terminals on the gas valve so you need to check the resistance from the top terminal to the middle terminal, and the middle terminal to the bottom terminal. The gas valve is located below the oven so remove the bottom drawer to see the valve against the back framing below the oven. You should get a reading of approximately 215 ohms. If you don’t get a reading within 10% of that number, you need to replace the valve because even though only one coil may be bad, the DSI board will stop all oven function as soon as it detects there is a problem with one of the coils.
