Hi Folks,

Have an Amana gas range model AGS5730BDW. First symptom was that the oven would not quite reach its set temperature, or would take a very long time to do so, intermittently. When I took out the oven bottom to observe the bake element, the igniter would glow, and ignite the gas in the bake element within a reasonable amount of time, probably around 30 seconds or less. The flames on the bake element would 'flutter' along the length of the tube, as if not enough gas was flowing to the element. The element would stay lit, but at what would seem to be only partial capacity. The holes in the element are clean, and without obstruction. Broil element ignites and seems to be operating with full capacity. Range top burners operate normally. Based on info from this forum and others, I replaced the bake igniter, suspecting that it might be 'weak' and not drawing enough current to keep the gas valve open completely. After replacing the igniter, the behavior in the bake element is the same. The gas ignites, but flutters back and forth along the tube. I have a short video (mov) of this behavior but it looks like .mov is not an attachable format.

So what should be my next troubleshooting step? Should I suspect the dual gas valve and replace it? I'd prefer to do more diagnosis rather than just replacing parts, if there's more I should check.

Thanks for any help you can provide,

Jason

That looks like too much primary air and the flame is blowing itself out.....close off the air shutter a little at a time to see how it effects the flame.

Ignore the pilot light, but the air shutter is in the same place...

Thanks for the suggestion and photo. My oven doesn't have a pilot light, but a hot surface igniter. I do believe there is a similar mechanism to the shutter you describe near where the gas line comes into the burner tube. I can post a photo of it tomorrow, as I'm working tonight.

Thanks,

Jason

Your solution seems to have worked...and thanks.

So now I understand you meant to ignore the pilot light in the photo, not in my own oven. I adjusted the air shutter as you suggested, and the flame become much more regular. Thanks for sharing your knowledge...much appreciated. Below is a video taken after the adjustment:
