I saved hundreds of dollars thanks to this video!!!!! Thanks a lot!
That's awesome! Thanks for sharing!
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!
We are happy we could help! Using a thermometer in the ice water is a great idea!
Great video. Straight to the point and a few tips at the same time.
Thanks!
The video is Sharp short and very clear. Thankyou
You're welcome!
Yea this is a good video, quick and not a lot of intro crap. I don’t give thumbs up often
Thanks! Glad we earned your 👍
Thank you for providing great videos to help us out like this
You're welcome! We are glad you found it helpful!
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.
Hello is there a temperature resistance voltage chart for LG refrigerators?
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?
Very good explanation. Greetings from creators from Indonesia. And always success
Thanks!
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
Thanks a lot for video.
We are glad you found it helpful!
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.
Good information
Thanks
Very good Lacture
Thank you!
what is ohm value for panasonic refrigerator NR-BX418GKMY. where to get the value schedule?
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.
Samsung model number beginning with 401 are manufactured by Samsung and should be able to follow the instructions in this video. We have a list of Kenmore manufactures here: partsdr.com/blog/who-made-my-sears-kenmore-appliance/
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.
The tolerances for most thermistors are usually plus or minus 5 to 10 percent.
Sweet!
hello dear, I had a refrigerator Samsung rt50k6000w, the fridge not cooling just cool to 12 degree Celsius and the freezer work properly, I was check the sensors (coil and air sensors) it read good depend the sensor chart , but this problem still existing the cooling not good in the fridge.
before 3 week of this problem the fridge closed by the ice , we stop the fridge till the ice melt and we check the fan and the sensors all is ok.
so what is the problem in this case? maybe the control temperature or other issue? if the control temperature is the problem how can i check it? (dial type A model, temperature control)
regards
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.
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?
You willl need to look in the manual for your multimeter to see what OL means.
@@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. When I went to touch the grommet the seal popped and water came shooting out. I guess over the years the rubber grommet opening got corroded and partially sealed so the water backed up and didn’t drain. 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.
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?
very good vedeo.
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.
Parts Dr Great. Thank you. Can you link the replacement part for me please so I can order the correct part.
@@gjhunter9326 We would probably need to have you contact us through our website and send us a photo of the part you are trying to replace so we can make sure we locate the correct part for you.
thank you
We are glad you found it helpful!
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
On most models, the ohm values are consistent for all of the temperature sensors.
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
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: ruclips.net/video/q7hysgipzpQ/видео.html
Straight simple
👍
thanks
We're glad you found it helpful!
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.
Good morning sir.
How are you.
I have frideg...the Hass company double door.
That not good cooling
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?
That sounds like it is testing good.
@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.
Good Sir
Thanks!
thanks.
You're welcome!
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.
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.
It could be caused by an airflow issue, most commonly a bad evaporator fan motor or the refrigerator not going through the automatic defrost cycle.
@@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.
@@rgrams1 What is the Model Code/BOM Name of the refrigerator? ruclips.net/video/4HhWL9sonuE/видео.html
@@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.
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.
There are many thermistors in a Samsung inverter refrigerator, located in different places
Are they the same? And interchangeable?
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?
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
The video showed a defrost temperature sensor. Is the temp/resistance table the same for temperature sensor and defrost temperature sensor?
On most models, all of the sensors throughout the refrigerator are the same resistance values.
I have Samsung RF28HMEDBSR refirigiter. I have set the temprature to 34 degree F. The temprature goes to 34 and stops. Then it goes to about 50 degree F before it turns on again. Is this normal or something wrong with it and how can I check? What is the normal temperature range? Please help.
How are you monitoring the temperature?
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
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: ruclips.net/video/rEB4_NGEpWo/видео.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.
Whare did you set your temperature?
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 samsung fridge's defrost sensor value 10.34 Is that fine that's new ?
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.
are the values the same for the temp sensor in the freezer?
The values are usually the same for all of the temperature sensors used throughout the refrigerator.
@@PartsDr thanks so much!
If my fridge is getting close to 0 or even -1 on the bottom shelf, but 3 celsius around the middle and top - what might that mean?
It seems to be getting too cold from the residual cold from the freezer. Have you seen this issue before?
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!!!
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.
The thermistor sensing its temperature should be about 5k ohm at room temperature 25C if it is a Samsung.
@@meisievannancy yep checked that.
@@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.
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.
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
I need a DS
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.
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.
