Thank you for including the temperature/resistance chart! This allowed me to determine that my sensor was working within spec. I also used a thermometer to get the actual temperature of my ice water - i was surprised by how "warm" the ice water was!
Congratulations for the video, this table applies to the entire line of Sansung refrigerators, the model is RS21HDUSW and the sensor code is Da32-00029n and the values are not in accordance with the table.
How close to the chart values should the sensor be for it to still be good? My machine's (RF32FMQDBSR/AA-00) temp sensor reads as follows 34.6 F 11.64k Ohms. The Chart says it should be about 12.4k Ohms. Is this value within tolerance or does the sensor need to be replaced? The fridge is not cooling but the freezer is fine.
I have a Samsung RFG297AARS, my fridge always freezes my foods. I want to find out where is the sensor, I see most refer to the sensor on evaporate coil, that should be the defrost sensor, right? How does the temperature in fridge be checked?
Yes, the sensor on the evaporator coil is for the defrost cycle. Often times the sensor is located in the evaporator cover assembly partsdr.com/part/da97-06323d-evaporator-cover-assembly
On my samsung fridge the resistance of the thermistor goes up when the temperature rises, and drops when the temperature drops. Do some Samsung fridges have PTC thermistors?
Thank you!, How likely that different Kenmore fridge used the same sensor? my fridge just not freeze "Fast enough" I don't know how to test the compressor or to know if there is a "very small" leak of the refrigerant that it is not able to compress anymore. The refrigerator side is cold enough but the freezer is not fast enough to keep the ice cream from melting. I took everything out and put a cup of water in there and the water eventually frozen. Thanks for the respond.

Cool video. But after defrosting. My samsung cooled until 2 degrees. I heard the evap motor spinning. After an hour it stopped spinning. The fridge gets warm. But display still says 3 degrees. Any advice here? I hear water droplets falling on the evap hotside and burning off
Ok so i opened up the evap cover panel. Looks like the fan has a little in out play. And had resistance due to rubbing on the plastics. I untightenend the housing a little. Now it works good
Can this be done at the PCB if I can find the correct wire on the diagram? My sensor is behind the ice maker. Will letting the unit run until I get the part ruin the compressor.
Can this be done at the PCB if I can find the correct wire on the diagram? Yes you can, but you would also need to know the temperature of the sensor to accurately test it.
My temp sensor is pretty close. Reads 33-34deg in ice water. Do you know what the voltage going to the temp sensor should be? I get 4.8V which I suspect should be 5V. My freezer is thinking it is at 0F when it's really at 15F
Question. Soft ice cream. Our Samsung french 4 door freezer is only cooling down to about 15 deg F even though the display indicates that it has reached the desired temp (set to -8 to test). This model's display shows the desired temp before it switches to what it thinks it measured ... also -8 deg. I replaced the T sensor in the ceiling of the freezer but no difference. The freezer coils and defrost drain are both clear. To test temperature I put a quick read thermometer in a small amount of water ... let freeze overnight ... and then read the ice temp in the morning.
@@PartsDr I noticed there are 2 fan motors in the freezer. They did spin freely by hand. Different fan blade designs. One to pull air in and the other out? If I remove the back cover and set it askew (still connected) and then plug in the fridge, should I see the fans both turning if OK? After replacing the T sensor the temp was going in the right direction (got to 5 deg F) but now it has been languishing at about 25 deg F for several hours. Fridge compartment and drawer holding steady at about 34.
Adding to the above, this morning the freezer was cold below zero close to where it should be, but then an hour later it was at 25 deg F again with no internal fan or compressor noises at all coming from the unit. Totally silent.
@@PartsDr RF4287HAWP/XAA02 (02 is for rev 02 made Feb 2012). I did dismount the freezer inside back panel, set askew, plugged fridge back in and let it start back up for several minutes. Neither of the 2 fans was turning. The top of the coils were frosted over but the lower part clear. Over time the temp ranged from 0 (left overnight) to 23 with 15 deg F being the average daytime temp.
Yes a failed temperature sensor can cause the evaporator fan to not come on if it thinks that the temperature in that area has already reached the set temperature.
Hi Danny, from our experience on most Samsung refrigerators, the sensors themselves are the same throughout the refrigerator but they each have different length wires and wire connectors. When ordering a new sensor, make sure to get the correct one by searching with the Model Code/BOM Name so it will connect without any issues.
@@PartsDr I am very grateful to you for all your help I have screen shot your temperature and resistance chart Samsung thermistor from your video based on room temperature and ice melting temperature The problem is that in Indonesia, we can not buy Samsung spare parts, unless we have our refrigerator repaired by Samsung In your country, is it the same?
Samsung Refrigerator RS267TDRS that fan when i did the test said 18.54 was using ohm 20k is that too high? fridge not cooling if display temp is 34 it really 40 have tested temperature thing it read 5.13 room temp 78 & ice after 6mins read 11.90 is that good or bad?
@PartsDr then could it be the Board on back of fridge bad o clue how to test that. I have had it plugged in for 3hrs display says 36 but have temp inside it reads 47. No clue if it has a damper can't find one.
When testing with a meter I get an ohm reading at room temperature in line with what your chart indicates. When I then put the sensor in ice water the reading increases as it cools - until it gets to about 9500 ohms - and then it goes to zero. As the chart says indicates it should continue to go up to around 13,000 as it approaches freezing - this would mean the sensor is bad, correct? Thank you
It sounds like the sensor is bad. You may also want to check to make sure your multimeter is on the correct setting and that it can measure up to 13K ohms.
Would you have the readings for an Electrolux fridge freezer temp sensor The defrost thermister reads 6.5 room.temp and just under 12 in ice water The temp.sensor in the fridge and freezer are wildly different Would you expect all the temp/thermister readings to be similar
I have a Samsung RF23M8590SG, what uses a sensor: DA32-00070K, instead of DA32-10104N, can we use a same data sheet for mine, what you were using ? Or mine suppose to be different?
The resistance value varies depending on the temperature. You will need to reference the chart shown at 0:43 to see if the value matches the temperature.
Great video. Hey if I put my refrigerator into forced defrost mode and I check the heating element with a temperature gun and it shows that it hasn’t heated up does that mean I need a new heating element?
There are other things that can cause the defrost heater to not heat. Test your defrost heater following the instructions in this video here: th-cam.com/video/q7hysgipzpQ/w-d-xo.html

My samsung fridge/freezer is too cold, freezing everything in the fridge part. Should I just go ahead replace temperature sensor, I do not have a ohmmeter? (There is no frost build up on any coils, did a full defrost and reset, and fridge froze a water bottle in less than 3 hours)
Hi Emily, That is really up to you. There are many things that work together to regulate the temperature of the refrigerator, so the problem could be caused by a bad temperature sensor but it could also be caused by something else.
My refrigerator a Samsung RF220NCTASR don't work properly. Frige and Freezer do not cool. All the fan work, but the evaportor is only cool in the upper side, the down is not too cool. What can I do?
Also, my fridge is working just fine, the freezer shows it it -5 but it is like 40-44... Can be the temp sensor bad to send a wrong data from the freezer lower temp, but not bad enough to get a right temp for the fridge?
You might want to remove the evaporator cover and see if the coil is frosted up. That could be causing the air not to circulate which could be causing your problem.
Okay I replaced the sensor but my fridge still keeps dumping water on the ice cube tray. What now???? I have a Samsung RS261MDRS. I bought that fridge back in 2012.
@@celloman78 I can't help except a bit with with the electronics and control logic. I find with all machines one must check the physical sequence of events carefully to see why any machine is acting abnormally. Of course you'd need to know what normal is and where the water normally leaves. I had a fridge where it's escape tube was blocked where the water is dumped into a plastic tray above the hot compressor so that it evaporates. Maybe it is not being routed as per normal as the route is blocked.
Thanx for the video. Great info. When I test the temperature sensor to room temp it gives the appropriate reading. When I put it in the ice cold water it reads OL. So does that mean the temperature sensor has gone bad?
@@PartsDr I checked everything and it all seemed to be working so I thought the drain just maybe clogged. I decided to use a pipe cleaner and go from the bottom up.

Hopefully, now that it can drain, the water won’t back up and freeze up in the fridge. Note to self, check the least complicated part first. But hey…now I know how to troubleshoot the rest of the fridge…so thanx for your help.
NTC Thermistors have a negative temperature coefficient. They are all rated at 25C. So a 5K ohm NTC thermistor will decrease in value as it's temperature rises and conversely increase in resistance as it's temperature decreases. You do get PTC devices but they are less commonly used in my observation. Samsung apparently uses 5k NTC Thermistors but you can get 1K 2K 10k and other values as well at 25C (or 77F). The rate at which they decrease/increase is specified in the datasheets.. If yours is 5kohm at 25C then it should be OK if is a Samsung.
I have the Samsung samsung rf4287hars/xaa which is giving the E 1 error code, bad freezer sensor in diagnostic mode. This model has the infamous freezer temp sensor mounted in the ceiling of the freezer. If it does test bad (which I'll have to do with it still installed, can it be replaced or is my fridge dead, for all intents and purposes?
I think the issue you are referring to is the wires that the temp sensor plugs into are breaking off in the liner of the refrigerator. If that is the case, then that is not repair able. If the temp sensor is just bad and you do not have any broken wires then it should be a pretty simple fix.

I bought 2 thermometers for the refrigitaor. I put them inside. Check temp when comprssor turns off. I see temp about 34. Check again when compressor turns on again. I see temp around 50. Generally if temp is set to 34 and refrigirator turns off when it reached 34. What should be the maximum temprature when it should turn on again.
@@ghulamnabi4214 I'm sorry, but Samsung does not usually publish that information. This is the service manual for your model here: www.dropbox.com/s/ny2029jd3z658cq/AW3-14_RF28H-141013.pdf?dl=0
I was told it has two sensors. Is that correct? My refrigerator is freezing from the back in about every 2 weeks. I tested fan and senor. Seemed to check out good.
There is usually one sensor on each of the evaporator coils for the defrost cycles, as well as other sensors placed throughout the refrigerator to monitor the temperature.
It could be a bad sensor. Sometimes a sensor will test okay a certain temperature range, but test bad at a colder or hotter temperature range. If this happens, the sensor should be replaced.
At what resistance of thermistor or temperature of freezer does defrost mode start? Does it depend on the thermistor resistance or duration like the conventional ones using a timer?
@@PartsDr Okey. Thank you for your answer I meant. If defrost cycle depends on the resistance of thermistor, I will try to replace the thermistor with a 20 kohm resistor (trial only) Does it come into "defrost mode/cycle"? In other words The main Control board is controlled by(the resistance of) thermistor?
@@dannyhindarto1818 It it usually multiple variables that determine when the refrigerator goes into defrost (time, number of times the doors were opened, etc). Samsung usually doesn't publish that type of information.
Hi, anyone able to help me locate the thermistor of a Samsung rl39thcsw fridge freezer please? I have located its wiring from the mainboard but cannot locate the actual sensor inside the fridge compartment. Is it a possibility that the thermistor of this fridge cannot be replaced? Could it be sealed inside the fridge casing?
I like how you don't say what constitutes a bad sensor... lol... is it that it doesn't show anything or that it shows outside the designated numbers. I have a RH22H9500SR. I get readings... at 70 degree's 6400-8500, at 32.5 degree's it gives me 17,000+. I can't find if these numbers are correct or bad
According to the chart, your sensor is off by 10F+ degrees. We would recommend replacing this sensor. Samsung doesn't specify that we could find, but in most cases, most manufacturers consider the sensor defective if the ohm reading is off by more than 5% to 10%.
@@wittchow A light layer of frost on the entire coil is normal. But, if the coil has excessive frost where you can no longer see the gaps between the fins on the coil then you have a problem with the automatic defrost system. Once the coil is clogged up with frost, the air can no longer circulate.
@@PartsDr I have frost all over the copper lines. I thaw it then plug back in and eventually freezer says -2 but it is around 32. I have the 4 door model RF23J9011SR/AA . The right side cool select freezer gets a few degrees colder than the left but not much.
What? Anything really outside those ranges. Broken, as in totally failed, will read like any other resistive electrical item...either totally shorted, or totally open...
When working on a refrigerator, you should wait 24 hours for the temperatures to cool down after working on it. If the temperature still isn't correct after 24 hours, then you most likely have a different problem with the refrigerator causing your cooling problem.
My fridge not defrosting properly I have check defrost sensor it's same value as you have menson 12.8k in ice and 5.2k in normal room Temperature, I have check heater, fuse, and defrost relay, it's all perfect reading even I check heating coil giving voltage from outside it's heating good. Ice melt only near-by heater area and ice frost on upper area of Evoptator Due to this problem lower part of fridge not cooling due air circulation blockage

I bought 2 thermometers for the refrigitaor. I put them inside. Check temp when comprssor turns off. I see temp about 34. Check again when compressor turns on again. I see temp around 50.
Generally if temp is set to 34 and refrigirator turns off when it reached 34. What should be the maximum temprature when it should turn on again.
@@ghulamnabi4214 I'm sorry, but Samsung does not usually publish that information. This is the service manual for your model here: www.dropbox.com/s/ny2029jd3z658cq/AW3-14_RF28H-141013.pdf?dl=0
I was told it has two sensors. Is that correct? My refrigerator is freezing from the back in about every 2 weeks. I tested fan and senor. Seemed to check out good.
There is usually one sensor on each of the evaporator coils for the defrost cycles, as well as other sensors placed throughout the refrigerator to monitor the temperature.
What was your solution? Facing similar issues
When I have the sensor installed in the freezer I can get a reading. Now that I have it out I'm it's not reading at all
It could be a bad sensor. Sometimes a sensor will test okay a certain temperature range, but test bad at a colder or hotter temperature range. If this happens, the sensor should be replaced.
At what resistance of thermistor or temperature of freezer does defrost mode start?
Does it depend on the thermistor resistance or duration like the conventional ones using a timer?
The defrost cycle is controlled by the main control board.
@@PartsDr
Okey. Thank you for your answer
I meant. If defrost cycle depends on the resistance of thermistor, I will try to replace the thermistor with a 20 kohm resistor (trial only)
Does it come into "defrost mode/cycle"?
In other words
The main Control board is controlled by(the resistance of) thermistor?
@@dannyhindarto1818 It it usually multiple variables that determine when the refrigerator goes into defrost (time, number of times the doors were opened, etc). Samsung usually doesn't publish that type of information.
Hi, anyone able to help me locate the thermistor of a Samsung rl39thcsw fridge freezer please? I have located its wiring from the mainboard but cannot locate the actual sensor inside the fridge compartment. Is it a possibility that the thermistor of this fridge cannot be replaced? Could it be sealed inside the fridge casing?
Yes we have run into that. Check out this video here: th-cam.com/video/rEB4_NGEpWo/w-d-xo.html
Good information
thank you
We are glad you found it helpful!
I like how you don't say what constitutes a bad sensor... lol... is it that it doesn't show anything or that it shows outside the designated numbers. I have a RH22H9500SR. I get readings... at 70 degree's 6400-8500, at 32.5 degree's it gives me 17,000+. I can't find if these numbers are correct or bad
According to the chart, your sensor is off by 10F+ degrees. We would recommend replacing this sensor. Samsung doesn't specify that we could find, but in most cases, most manufacturers consider the sensor defective if the ohm reading is off by more than 5% to 10%.
My temperature sensors seem to be working but the freezer says it’s -2 but it’s actually only 32
Check to see if you have frost buildup behind the evaporator cover. th-cam.com/video/2VWGWPB0wxM/w-d-xo.html
Yes there was frost. I let it thaw but same issue still
@@wittchow A light layer of frost on the entire coil is normal. But, if the coil has excessive frost where you can no longer see the gaps between the fins on the coil then you have a problem with the automatic defrost system. Once the coil is clogged up with frost, the air can no longer circulate.
@@PartsDr I have frost all over the copper lines. I thaw it then plug back in and eventually freezer says -2 but it is around 32. I have the 4 door model RF23J9011SR/AA . The right side cool select freezer gets a few degrees colder than the left but not much.
@@wittchow Is the evaporator fan motor running to circulate the cold air?
very good vedeo.
Would have been neat to see what a broken reading looked like as well.
What? Anything really outside those ranges. Broken, as in totally failed, will read like any other resistive electrical item...either totally shorted, or totally open...
thanks
We're glad you found it helpful!
thanks.
You're welcome!
I did change mine and the temp. still 62 degrees after 3 hours,any ideas?
When working on a refrigerator, you should wait 24 hours for the temperatures to cool down after working on it. If the temperature still isn't correct after 24 hours, then you most likely have a different problem with the refrigerator causing your cooling problem.
Straight simple
👍
Good Sir
Thanks!
If it’s showing 0, does not mean its broken?
If you are receiving a reading of zero, either the part is bad or you are not testing it correctly.
Sweet!
My fridge not defrosting properly I have check defrost sensor it's same value as you have menson
12.8k in ice and 5.2k in normal room Temperature,
I have check heater, fuse, and defrost relay, it's all perfect reading even I check heating coil giving voltage from outside it's heating good.
Ice melt only near-by heater area and ice frost on upper area of Evoptator
Due to this problem lower part of fridge not cooling due air circulation blockage
It could also be a bad main control board or an intermittent bad thermistor that tests good but fails during use.
@@PartsDr ok thanks For help will find out fault and reply you when fault solved🙏 Thanks again
My only problem is where do I get ice water when the ice maker in my Samsung refrigerator is broken yet again...😂
But seriously, your videos are awesome!
@@stacybradford Thank you!!!
I need a DS
