The drop in flame aluminum piece that supports the enameled flame spreader doesn't seem to sparking from the igniter. I've cleaned it. I figure the igniter is good because it works intermittently. All of the burners spark when you try and light any one of them - except the larger front burner.
The oven problem has gotten worse. Now the oven (broiler, upper burner) which always lit, will go on, and then cut off after about 20-30 seconds. If I hold the knob in after the flame ignites, and back off a little so that the igniter stops firing, but I am manually allowing the valve that controls the flow of gas to keep flowing, the flame will stay lit. But if I let go of the knob, the flame goes out.
This is the same thing that was happening to the lower, oven burner. To ignite the oven, I have to turn the oven knob to temperature and hold it in for 20 clicks of the igniter before it will stay on - then when I release pressure on the knob the oven would stay on. Now, both of them, if they will light at all go off after 20 seconds.
What should I clean? Are parts bad? loose connection? Is there a thermocouple that has to get hot enough in order to keep the valve open so gas continues to flow to either the oven or broiler?
thanks for your help.
