Our 2 year old Whirlpool stainless steel microwave finally quit opening with the push button. After pushing the button and opposite end at the same time to open it for a few months my husband had the bright idea to simply open the door and push down on the top edge of the door closest to the button. Miraculously it began opening with the button!!! Haven't had an issue with it for several weeks and will be trying this should it happen again. Worth a try ;)
