I was cleaning the microwave this morning and noticed that the front panel was coming apart. I can see where there is an edhesive that is separating. I called sears but they say they can only recommend full door replacement which would be stupid because for the cost of fixing it there way I could practically replace the oven. This oven is out of warranty by 3 months. Too bad I didn't notice it earlier because it has probably been separating for some time. Any recommendations on DIY?
