Hi- I have the above Jenn-Air Convection Microwave which up until the past week is working great - over the range style which now has a bug that is driving me nuts. Seems it started with after using the microwave the to vent door which opens during use will open and close after use. This unit did this right when we purchased it once and stopped after I unplugged it for a minute. Now I can unplug the unit for 10+ minutes and it continues to open and close.
The fan itself does not turn on after use and you can manually turn the vent fan on and adjust the speeds from the front panel as you should. First I thought this was a heat issue but it will do this even after running the MW for a 30 second cycle.
Any ideas? maybe a dirty sensor if so where is the SOB and how do you get to it. If not what does one think the repair cost would be?
