Product review (5 stars): Perfect replacement for my LG Microwave Oven
Recently the button for my LG Microwave that opens the door fell out.  It has three tabs that should hold it in place, but all three were broken.  The part number was molded into the piece itself which made it easy to  find this replacement, however the last character of the old part number was an "A" while this part has a last character of "B".  That appears to just be a part revision number.  The new "B" style part fit perfectly.  The first button lasted about 8 years.  Maybe in another 8 I'll be ready to get a new microwave.
