Hello, I have a problem with my oven that maybe you can help with. It is an Amana AGR5844VDD1 that I purchased four years ago. I noticed that every time I'm cooking something in the oven, the oven will preheat fine and reached the specified temperature as it should and then, about an hour later, the oven temperature will decrease drastically. For example, if I'm cooking at 450 degrees it will hold that temperature for about an hour than the oven temperature would decrease to a point where you could actually put you hand in the oven without getting burned. The flames are still on in the oven and the digital temperature display still shows 450 degrees, but for some reason, the temperature would cool off and never go back up to the original setting. This obviously makes it impossible to cook anything that requires to be in the oven for over an hour as it will not maintain the temperature setting. I appreciate any help you can offer.

I would like to thank the HumboldtRepairMan for making an excellent diagnosis. It turned out to be a weak ignitor. Thanks again.
