Gas range works, broiler works, oven stopped working in the middle of baking. Glow plug gets hot, but oven will not light. No error codes and I turned off the power to reset the electronic with no success. Any idea what I should try next?

Paul, I called my local parts distributor for advice. After checking both glow plugs for the broiler and oven, both bright orange. I attempted to light the over the regular way with the key pad while tapping on the gas valve and regulator. The oven lit. I ordered a new gas valve and regulator, about 140.00 dollars. It will come in this Friday. We shall see if this fixes the problem.
