How to install temperature sensor and defrost sensor

My fridge has been warm while the freezer is still cool. I’ve been told it could be the defrost heater and would require a new evaporator assembly but I’m trying the sensors first since they are (or were supposed to be) cheaper and easier. I ordered DA47-10160H and DA32-00006W per customer service on here but now that I’ve received them I can’t figure out where to install them in order to get my fridge temperature working properly. The evaporator in the fridge side behind the drawers was all iced up so I defrosted that to get a look at things but the only sensor I saw looked more like DA47-00095E than the defrost sensor I was referred to… I was also told to put DA32-00006W in the freezer but that seems wrong to me since the temperature in the fridge is what’s not working… I read somewhere that it might be at the top near the light in the fridge…?? Any help you could provide would be great. We have it defrosted and operating but mostly taken apart so I can look at it relatively easily. Thanks in advance for your help!

I haven’t gotten a reply and my fridge has gotten warm again. I’m really hoping to figure out where to install these so I can do it tonight. Please help if you can!
