How to Troubleshoot & Replace Samsung AP4237456 / DE96-00414A Microwave Door Latch And Switch Assembly

With your part work well 

Tested door interlock switches. Found one switch bad. Ordered the door interlock switch bracket assembly (which, by the way, included all 3 new switches. Installed assembly in 15 minutes. Works perfectly now. 

1 out of 3 of the door switches was faulty. (From my household SLAMMING the door). I did not feel like messing around with possibly picking the wrong switch so I ordered this whole assembly. Really easy to install. Just take a pic of the wires so you don’t forget where they go. Also as a heads up. Just take the control pad off. It is totally in the way while working on this. Make sure it’s unplugged and discharged. Also note if you are getting just the switch. Be aware that two of them are normally open and one is normally closed. 

Replaced door assembly. Remove top grill. Remove cover over control panel. Unplug all wires from circuit board. Pull out door sssembly and replace. $15 part instead of new microwave. Very proud of myself! 

I removed and replaced the door latch switch assembly. Before doing so, I reviewed a number of different online videos to make sure I had the gist of the procedure, which also involved removing the microwave from over the oven and re-installing it afterwards (both are a two-man task for most people). After getting the microwave down with the help of my neighbor and having removed the cover, I followed the procedure recommended by 'misterfixit' to safely discharge the high-voltage capacitor without damaging either you or the capacitor. (He used a heavy-duty 150K Ohm 25W resistor, which I didn't have. I found that a 600W-rated incandescent dimmer switch works just as well.) Once that was done, it was fairly straightforward to remove and replace the latch switch assembly.
