How to Troubleshoot & Replace Lg AP4650822 / 6600JB3007L Refrigerator Door Light Push Switch

After replacing ice maker,all door switches,mainboard,sub relay panel,water inlet solonoid ,It turned out to be a defective left side door switch! The moral of the story,"just because the part is new does not mean it is any good". the end but it works great thank-you! 

I replaced the push switch. 

Replaced according to video - very easy 

Called, order a new one and it was a very easy fix. Great job. Thank you... 

..I sent a question to one of the Pro's, he diagnosed the problem right away. I ordered a six dollar part and installed it in minutes. This is the third time Appliance Pro has helped me save hundreds of dollars. What's not to like about a company like that?!! Five stars!! 

Traced problem by diagnosis of symptoms. Found mechanical door switches were both bad. Then did part search online and ordered from lowest cost vendor with acceptable shipping charge. 

The light in the fridge would not go out ,this was making things warm in the fridge.now here comes the good part. since i have double doors i ordered two push switches.and on the same day asked the techs at app (appliance part pros) the question about my light staying on. come to find out the switches were not the problem. i needed the mcb (main control board) they gave me the part no. i ordered it . just needed a flat head and phillips screw driver and 20 minutes. the how to videos were very helpful. i'm very satisfied with the results and service ,and learned a lesson also to ask your question first. :-) 

I replaced all door switches , even lower freezer compartment (age ), and all upper switches .light socket note it has a heat protection now inline as to open one side off line ( aka upgrade ). Very easy to do , made high points with the wife .
