How to Troubleshoot & Replace Samsung AP4671804 / DA32-00029N Refrigerator Temperature Sensor

Replaced the motor in the Fridge panel Part # AP4136543 (DA31-00020E) and temperature sensor Part # AP4136842 (DA32-00006W). I made two orders, these are the correct parts. First sensory I ordered was the correct one actually. Note to whoever, the motor is the same for the freezer or fridge..it says #7 with black marker on all of the motors. Steps to fix: Remove the Cold veg etc Bins and Phillips screwdriver is all you need and unscrew all you see and pull the panel off. You do not need to unscrew the panel going down the midde of the fridge, just the ones behind the cold bins. Replace the motor in the panel you removed, unplug it from the fridge to make it easier. You will need a flat screwdriver to pry gently the motor cover and then pull hard and wiggle the motor out. next defrost the evaporator( I used a space heater and it took minutes), because its probable got ice on it so you can see the temperature sensor witch is two yellow wires and the sensory is white enclosed in a little housing. The Temp sensor sent to me was black but its exactly the same thing other then color. Both are yellow wires. Plug everything back, turn on the fridge and wait a few hours for the fridge temp to reach 36 degrees or your setting. The freezer side will decrease almost immediately and reach temp setting first. Fridge side takes almost 30 minutes or longer to start coming down and hours before getting to the 30s. 

I ordered a new defrost sensor and defrost fuse. I am a widow and had no clue how to fix a refrigerator but with your how to video's and research I was able to do it myself. One bit of advice the frost will adhere to the plastic panel so you must let it defrost itself before trying to remove that panel. If not panel will not come off. 

Replaced water inlet valve with help from relative. Two refrigerator sensors replaced. Parts ordered with help from appliance parts pros. Once parts arrived, videos showed step by step process. After months of thawing out fridge, throwing out spoiled food, etc. I finally have water, ice and food so far is still fresh!
