I Googled the symptoms that we were experiencing with our Frigidaire gas oven and found a video from Appliance Parts Pros. The technician in the video described the same symptoms, and how to do the DIY replacement of a Gas Oven Ignitor. Of course, I ordered the part from Appliance Parts Pros, received the part in two days, took 30 minutes to replace the bad ignitor, and my problem is solved.
