Maytag Oven Bake Light Flashing

[SIZE=4]Recently my Maytag MEW5627DDB wall oven upper oven bake light started flashing. It will get up to temp, then after a few minutes the light starts flashing and the oven starts cooling down. I replaced the sensor thinking that was the problem, but it did no good at all.[/SIZE]

[SIZE=4]Anyone have any ideas? It is not throwing off an error code, unless there is a way to put the oven into troubleshoot mode or something. If there is a key combination to press to get error codes, I have no idea what it is. I would prefer to not have to call a tech out since I live in the boonies and hate getting strapped with and additional $100 trip charge just to drive out.[/SIZE]
