I took that pannel out this morning and found the fan. I think it should spin free with the unit unpluged but cannot turn the fan. So looks like time to call repairman. Bought it about 5 years ago new. I can replace it with something close for $674. I have no idea where my wife would have stuck any paperwork for it or any of the other appliances so don't even know if the oven in stove is a self cleaning unit or not. Have no Idea if the extended warenty was bought or not. If was probably just out of date. After 2 1/2 months the attorney is starting to settle things. But looks like we will not have to go to probate as did not have enought assets to require that.
