How to Troubleshoot & Replace Samsung AP4136952 / DA34-00006C Refrigerator Door Switch

At first I thought it was the bulb, but after buying a new bulb from Appliance Parts Pros and the problem not being fixed I quickly realized it was the switch. So, I went right back to Appliance Parts Pros and found the door switch. The part received very quickly and, voila, I can finally see what's in my fridge. 

Very simple repair, pop out old plug in new and all done. Repair took less than 1 minute including opening box. Great service from Appliance Parts Pros on line store...Thanks 

Replaced it 

Installed a new door switch 

I remove the part by popping out the sensor and than unplug the socket and inserted the new peace
