The igniter appears to be working just fine. It lights up the same as the one for the bottom oven. The bottom oven works but the top does not.
Thank you very much for your help. I was skeptical at first since the igniter did seem to light up but the gas valve would not open. After receiving your answer I went home and removed the igniter from the bottom oven and installed in the top one. The oven turned on without any problems. I ordered the part you indicated, installed it and the oven has been working ever since.
