Bryan for Model Number WFG374LVQ0 Oven will not maintain temperature. Top gas burners work great. Broiler works great Set the preheat temperature, press start and it starts right away (you hear the gas come on, and the bang of the igniter). Then it will cook for awhile and the temperature will fall and fall. The gas does not seem to be coming back on. I don't hear any bang from the igniter. Hit cancel and preset the temperature again and about half the time it goes back up to temperature. It might stay at the proper temperature for 20 minutes, but will fall. Already replaced the oven temperature sensor. Could it be a bad igniter, or valve?
