How to Troubleshoot & Replace Lg AP4990892 / 3501W1A053A Door Latch Holder Assembly

Had to replace the whole side bracket that holds the switches, not too hard to do. 

I took the microwave case off and checked each switch after it started turning on when opening the door. One switch had shorted out. The switch board had a couple parts which broke as it seemed to be a bit brittle so I replaced that as well. The microwave is back to normal. 

I bought the switch assembly took me about a half hour to install. Everything works good now.
