How to Troubleshoot & Replace Samsung AP4139993 / DA61-01800A Refrigerator Temperature Sensor Bracket

Took the ice maker out inserted the loose sensor into the sensor bracket then put the senor bracket cover on and place the assembly into the ice maker. You can find youtube videos as to the process. I found it much easier to remove the ice maker to get the parts into their correct places. Now ice is in production as it should be all loose. 

Replaced missing parts that positioned sensor underneath ice cube tray. These two parts had fallen into ice maker a while back and I discarded them thinking it was packing material. 

I replaced the sensor bracket and cover plus the ice cube tray 

I slid the hard plastic "cover" over the foam "sensor bracket", placed the sensor in the obvious molded spot in sensor bracket, pressed the cover/bracket assembly onto the ice cube tray so it would make good contact and snapped it into place, and finally ran the sensor wire through it's guides. Works great! The most time consuming part of the job was removing the freezer contents and then the drawers so I could lean into the compartment and see where everything went. But that was a good excuse to clean everything, and the freezer now looks "good as new". 

After defrosting freezer and removing old sensor mount and guard replaced with new parts. 

Removed the icemaker and replaced the ice cube tray, repositioned the sensor in the sensor bracket, and replaced the cover. The ice cube tray and cover plastic had broken in a few places. This icemaker has been trouble since the start - always breaking and freezing ice cubes together, or breaking the ice into small pieces. After this repair, all is working like new again! 

It almost seemed like the ice was sticking to the ice tray, so, when expelling the cubes, instead of dropping into the bin whole, some would just shatter, while others were never released and remained in the tray during water refill. As a result, solid ice was forming in the bottom of the ice bin, and just a small amount of broken ice was being produced. The Ice Cube Tray was replaced and it is now working normally. 

Watched video on line. Ordered parts,( which were delivered very quickly), that were easily replaced. Ice maker fixed. 

Replaced the sensor bracket and cover for the lower ice maker. 

I ordered a new tray sensor bracket and cover and was able to fix the entire problem in under $10 min for less than $60!! What a deal!
