How to Troubleshoot & Replace Samsung AP4136048 / DA47-00095E Refrigerator Defrost Thermal Fuse Assembly

Found repair manual and used self-check to confirm that the thermal fuse and temperature sensor were at fault. Thankfully I bought 2 thermal fuses. All the videos show the condenser coils in the refrigerator (we have a bottom freezer). So emptied it out and took it apart to the condenser. It had ice on it which I was expecting and some black burn marks (making me think that the fuse maybe burned up). Replaced fuse and sensor. Used opportunity to thoroughly clean all the shelves which were needing it. 30 minutes later, freezer was at 25 degrees again. Turns out there is a condenser in the freezer section too (makes sense now). So emptied and apart came the bottom freezer. That condenser was a solid block of ice. Had to use hair dryer to thaw it before I could work on it. Replaced fuse and sensor and working perfectly now, running at -2 degrees. No harm, no foul, but ended up taking 4 hours since I had to do both sections and its my own fault for not thinking there would be a condenser for each the freezer and the fridge. On the bright side, gained the experience and now can add fridge repair to my DIY resume! 

Replaced temp sensor, thermal fuse. 

Replaced the thermal fuse which came quickly and fit perfectly. Thank you 

There were three things that were done to repair the refrigerator. 1st) and 2nd) I replaced the Thermal Fuse and the Temp Sensor, 3rd) Cleaned the door gasket and rescued the freezer door hinge that was loose and rubbing. Now both the refrigerator and freezer work at their desired temperatures. 

I looked up the parts that seemed to be related to freezer temperature, bought them, received them, and installed them. Freezer works great! Thank for all the availble info, I'm no appliance professional. 

Replacement of thermal fuse and temperature sensor. 

Easy . just replaced a new thermal fuse. 

I order new thermal fuse and installed and it been 5 day still working fine. 

Replaced the temperature sensor and thermo fuse. Looked like the defrost was not working, possibly due to bad sensors so looked to switch out the sensors that directly relate to temperature and defrost control. Took about two hours, mostly due to melting the ice build up on the coil. Easiest part of the fix was the parts were received the next day after ordering. Great response time from Appliance Parts Pros. 

Replaced thermal fuse after checking to see if it was defective. After installing it the freezer got too cold, I unpluged it an plugged it back in , Been working like it should for two day's now.
