Bill for Model Number Jenn Air built-in wall oven (don't have exact model #) So over the past 6 years I have replace the high limit switch (part # 74009837) probably 5 times. It would often fail after a self-cleaning cycle so we stopping doing that much at all. I didn't used to mind because it was a $13 part. Now the same part costs over $50. So now I am trying to figure out what might be causing this part to keep failing. The fan seems to be blowing hot air out from under the stove so I think it is venting OK. What else could it be? Thanks
