Was broken
The repair was not the issue. When I received it there was no protection packing, no invoice and if you call the number, no one is there to help. The rack was plastic with no protection in box and it was damaged. Tried to resolve this matter with no response. Will never go through part select again.
The bulb wasn't the issue so I was hopeful the switch was. utube helped me some, but figuring my model was different than any on utube. Got the switch in and plugged it back in. Moment of truth. Didn't light. Ugggh! Out $50 for switch plus $20 for nut driver set.
Figuring out how to remove the cracked door rack was the most complication I had. Once I figured out how to push it up it was easy to remove and then replace it with the new part by just placing it over the nobs and pushing down. No tools needed, just hands.
Door switch was no longer making my light go on when door opened
I used the youtube you provided. It was pretty straight forward, but I had to make a trip to the hardware store for a bit (hex wrench) to remove the hex bolt head style screws. I was only expecting to need phillips or flathead. I managed to remove one with a set of pliers, and the brought that example to the store for size reference when buying the bit to fit my black and decker drill. The rest was easy.
Evaporator was freezing up and was running non stop
I tested the components in the refrigerator defrost function. I used digital multimeter and checked for continuity. Defrost thermostat must 32 degrees or lower.
Thawed out freezer, I recommend laying a couple old towels in freezer to soak up melted ice. Replaced old thermostat with new part. Removed 2 screws, removed back plate, unplugged 2 connectors and cut 2 wires. Crimped in new thermostat and repositioned to original part location. Reconnected plugs as I reinstalled back plate. Installed 2 screws and connected power. Works like new! Trouble shooting and part installation video is very helpful, great site!
