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

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!
