Yes they all work. The light does turn orage and then red. I've seen the flame intermittently through the rear vents. It just doesn't get hot enough. Unfortunately I don't have an infrared thermometer. At 350* it gets hot but I can still touch the surface. At 450 with the oil on I didn't touch it, but it didn't burn after 20 or so minutes.
Thank you. I'll relay that to Matt in the morning. I was hoping it was a quick fix. Have a good'un!!
