About every 3 months ice forms around fan behind rear panel inside fridge, which causes loud humming noise. I then defrost with a hair drier and everything is ok for about 3 months. Could this sensor be the problem or is it most likely the defrost heater?
For model number RF28HFEDTSR
Hello Patrick, Thank you for the question. I recommend testing the sensor. The best way to do this is to remove the thermostat from the refrigerator so you can control the temperature of the sensor. You can let the sensor warm up to room temperature. With the sensor warmed up to room temperature the sensor should read approximately 6.2K Ohms at 68°F. With the thermistor submerged is a glass full of ice water, the sensor should be very close to 32°F which should read approximately 16.3K Ohms. If the values that you are getting are far off from these readings, then the sensor is bad and should be replaced. Hope this helps!

Fridge is freezing everything inside. Fridge temp on display panel is blinking. Would this be the part i need?
For model number RF263BEAEBC
Hello Cole, thank you for inquiring. Yes, the Temperature Senor is a likely cause. This part number PS4138666 is the compatible replacement for your model refrigerator. You may also want to consider the Damper Motor, part number PS4138340. Good luck with your repair!

The refrigerator keeps freezing up and i even put the temp on the door up to 44° degrees and it still freezing up . What part # do i need?
For model number RF25HMEDSR
Hi Robert, thank you for your question. When you are having temperature problems in your fridge, there are a few parts that could cause the issue. You can use a multi meter to test most of the parts. Make sure you cut power to your appliance before doing any repairs or tests. First you should test your defrost thermostat. Place the thermostat in ice cold water for 2-3 minutes after removing it from your appliance. It should be reading 0 ohms to be working correctly. Another part to check would be your defrost heater. Remove it from the appliance. It should be reading anywhere between 0 - 50 ohms to be working. You could check your temperature sensor. To find the correct reading for this part you will have to refer to your tech sheet that comes with your appliance. You can usually find this tech sheet behind the bottom grille of your fridge on either the right or left side. These are the most common parts that cause this issue in your appliance. So it is suggested you check them first. I hope that helps. Good luck with your repair.

Freezer not cooling, fridge working fine, coils not getting cold. Could it be this sensor px-41c,aw3-da32-10104n
For model number Rf28hmedbsr/aa
Hello Dennis, Thank you for the question. We suggest testing the sensor. At 70 degrees the resistance should be 9.3K ohms, 90 degrees would be 7.7K ohms. at 100 degrees would be 6.2K ohms, and 120 degrees would be 4.3K ohms. If the thermistor reads outside of range then it needs replaced. We hope this helps.

Freezer not working, fridge working fine. Serial #065l43bf509802t
For model number Rf28hmedbsr/aa
Hi Dennis. Check the evaporator fan, compressor and if the coils have frost buildup. If so you may need to manually defrost your freezer. Thank you for your question and good luck with your repair.

I have error 5E: Fridge Defrost Sensor Error and the coils freeze every month or so, requiring me to do a full defrost. Is this the correct part for my model? DA32-10104N, PartSelect Number PS4138666.
For model number rf4287hawp/xaa
Hello Stephanie, thank you for your question. Our recommendation for your issue is to replace the Defrost Heater PS4140530. We hope this helps.

What is the purpose of this temperature sensor? I believe this part has broken off and fallen into the top freezer drawer. The unit seems to still function properly. Thanks.
For model number RFG293HARS
Hello Ron, thank you for your question. The Temperature Sensor in your refrigerator senses the temperature and sends the information to the Electronic Control Board. If the temperature in your refrigerator is not accurate, it could be due to the Temperature Sensor. I hope this helps!

Evaporator frozen (refrigrator section) and allowing top section to lose cooling
This is the Samsung French door refrigerator style that so many people have complained about freezing up and not cooling the top section. I first changed out the defrost thermostat and this did not correct the problem. I done a quick resistance check on the temp sensor that's mounted on the evaporator itself. The resistance would change when holding an ice cube on the sensor so I just assumed it was ok. PLEASE TAKE NOTE: When performing a resistance check on this sensor, make sure your readings match the Samsung temp/resistance chart in their literature. My sensor was way off calibration and was causing the freeze up. Its working as designed now and DW is happy again. Learn from my mistake.
