Mine didn't have the access panel on the left, so there was no good way to oull the back panel downwards. I put one of the screws that held the funnel that directs cold air to the ice maker back in, hooked an old clothes hanger over it, and used that to pull down. Worked a charm!
I'll confirm it is the defrost HEATER (that long u shaped coil) that needs to be replaced - not the defrost sensor and certainly not the control board. After spending $500 on a bad diagnosis, and research into this on YT, I got a third tech to order me the defrost heater. It's been 5 days and the issue is solved, finally. It's a $40-$50 part. This model is a bit more complex than my Kenmore-branded LG but at the end of the day it's the defrost heater underneath the evaporator - not just the "thermister" or fuse or "sensor".
Ty so much for your video !! The error code was the defrost sensor. Bought it on Ebay for 30 dollars canadien, replaced it and boom I am back in business!! Ty again.
Very good explanation. Greetings from creators from Indonesia. And always success
Gorgeous. What is the value of the sensor in kilo ohms?
My original part looks quite different. There is a black wire coming out of the top connector that goes into the coils. The model number is LFX28968ST. The part number is LG 6615JB2005N, which is supposed to be the replacement part. Is it the wrong part?
Plenty of replacement videos, just none on testing the same one. lots on testing the bimetalic type, too bad they do not apply.
My LG has a thermistor in the refrigerator section and freezer. Currently the temperature in freezer is fine, but in the fridge section it is getting too warm, staying around 48 degrees. There was a block of ice on the evaporator coils (fridge section). I verified the heat element works, but since there is an evaporator in the fridge and a separate one in the freezer section, which defrost sensor would I change, the one in the fridge or freezer?
I have an lfc25776st LG French door refrigerator. Periodically a fan runs and makes a rattling sound. It stops when any door is open. My research says it may be due to frost buildup in the freezer caused by a faulty defrost sensor. Is this the same part the video is about?
Where can I find the temperature / resistance chart for the thermistor changed in this video?
Ohh I forgot my fridge is the lg LFX23965ST 2009 model. Ty again.
I have an LG Fridge LFX2596AL. What is the difference from p/n 6615JB2005H and p/n6615JB2005N? Under search for my model you're calling it a "Defrost Sensor" as opposed to a "Thermistor". They look exactly the same yet they are different by a couple of bucks. BTW...loved the video! I know it will help me replace my Thermistor/Sensor....lol. Cheers!
Very good

Hello. I'm really hoping that you can help. We have a 3yr old LG model LFC2575ST. For several months it has been randomly freezing food in different areas of the fridge & vegetable drawers. We have unplugged it, ran diagnostics (it came up w/nothing), moved food around in freezer & fridge to be sure the vents weren't blocked & raised the fridge temp to 44 degrees. Nothing helps. I'm hesitant to spend $400 for a repair & am considering just buying a new fridge (different brand of course). Any advice you can offer would be greatly appreciated.
I feel like I am back at work. (I am retired) I use to write Plans using the same verbiage used here. its funny
Hi..I have a lg LMX25964 refrigerator . It stop cooling completely..what might be wrong. I do need your help to find issue to fixed.
I have a LG SXS Regridgerator model # LSC21943ST. the fans are running but blowing warm air
Tamra Meyers Here is a link to our repair help page. The possibilities exceed the space we have here. www.repairclinic.com/RepairHelp/How-To-Fix-A-Refrigerator/51-200-684445-/LG-Refrigerator-not-cold-enough-LSC21943ST?TLSID=1773
So, I'm looking at doing this replacement/repair job on my fridge. Showing the prototypical dH f error and saw some frost buildup (but not a lot). I'm getting an open short across the heater element so I'm assuming that it's fuses are blown, but I'm also looking at the controller board. There's a flyback diode in parallel with the relay coil for the heater that's shorted. Is this the common board failure with this issue? It makes sense to me that a failure of the heater might also blow this diode since it seems likely that there was some sort of overcurrent in the heater circuit. I'd rather get away with replacing a $1.04 diode instead of a $200 control board that's mostly fine. Haven't taken it apart to test the thermistor or the heater yet.
I need a defrost sensor for this fridge GL-B562GLPL /GL-B562GQPL
Can you help me with the model number?
Help Anyone. Going by symptoms alone how do you tell if the problem is the thermistor or thermostat?
hi. my premium 8 ft freezer i connect the thermal swich and is on the off position ! when i plug it to the wall is goes on anyway !! and. when i. turn it to the on position it pops the brake on the electrical main box !! can you help ?
My refrigerator looks just like this one but is Kenmore 596.72003014. Problem is that freezer is not defrosting. Does this same part #6615JB2005C fit my refrigerator?
Is there a way to force defrost it
blow dryer
I replaced this defrost thermister on lfxc24726s and it did not fix The problem of ice building up on the coils.
In addition to the ice building on the coils, The freezer is not the correct temperature, it's 36°f instead of 0°f, And the ice is not producing.
What should I check next? Defrost board? Defrost heater?
Something else?
No error code.
Thank you!
Old comment, I know, but did you ever figure out what the issue was? Mine has started doing something similar.
I don't think I ever fix it I don't remember sorry@@mbt841
Does anyone know the part number for that little sensor with the blue wires that goes thru the panel? I can't find it anywhere, I assume it's the freezer temperature sensor.
That sensor is called the "cover sensor" and it is part number ACQ73244001
It can be found here: www.repairclinic.com/PartDetail/Cover/ACQ73244001/1525609?TLSID=1773
Hmmm...the Model # on label on inside of Fridge is LFX25961AL/00...Serial # 904KRPV02784. I went onto your website and found a link for parts for LFX25691 and its indicating Defrost Sensor with Fuse RepairClinic Item # 1266868. (6615JB2005H). Curious. Thanks for the response.
I have an LG like this and it has a sheet of ice in the bottom and is leaking. What part do I need?
Ian McDonald Enter your model number into our repair help section for details on what parts could cause this problem. www.repairclinic.com/RepairHelp/How-To-Fix-A-Refrigerator/55---/Refrigerator-not-defrosting?TLSID=1773
clean the drain at the bottom of evaporator it's probably clogged.
Mi refrigerador LG Model LFXS30726S dejo de enfriar y no se la causa
nice
Will this disassembly also work with a Maytag fridge?
Tim Hoeft No it will not. Unfortunately we do not have any Maytag refrigerator videos. Sorry about that.
Hi there! I have a LG double door fridge model no. GR-L207FLQ. It started to fail blowing and cooling the fridge section. Now the freezer section has also stopped. Everything else works normal as it sounds the tone if door left open for. If it is unplugged for few hours and replugged later it cools but not long. What could be the problem.
+dumisani nxumalo Could be a bad fan motor or control.
+RepairClinic.com there are two fans inside. Which one could be the problem and which control should I check?
Yes, that is what we are seeing as well.
i have lg model Model GR-M562YLY APLRLML S/N:8051NSE00006, THE FREEZER IS WORK AND THE REFRIGERATOR IS NOT COOL. Pls advice what should I do, can you show me how to see in the You Tube troubleshooting, WHAT IS THE PART SHOULD I REPLACE? THANKS
i have lg model LSC26905TT, THE FREEZER IS WORK AND THE REFRIGERATOR IS NOT COOL. WHAT IS THE PART SHOULD I REPLACE? THANKS
+hao nguyen Look for a bad evaporator fan motor in the freezer as it circulates air between the two compartments.
Lg model LFXS29766S displays F dH error code for a few days and power cycled to reset a few times now and the temp are on the rise barely cold now. Any thought on part suggestion or schematic so I can troubleshoot? Thanks
@Scott Norman
Where you able to find the problem?
I have an LG model LFX28978SB. Not cooling properly: fridge is 46F and freezer is 32F. Is the defrost thermistor the part I need?
This should help click here: th-cam.com/video/5vA8Ksv5kVY/w-d-xo.html
I have an LG LFC28768SW Refrigerator and it is not cooling at all (fridge or freezer). I don't feel air blowing in the fridge or freezer. Any ideas?
This should help click here: th-cam.com/video/5vA8Ksv5kVY/w-d-xo.html
my problem seems to be backward from everyone else. Unit is LG LBC22520SW/1. Freezer won't cool below 35 degrees but refrigerator works fine. Coils are clean and plenty of air flowing so it's not fan related. Replacing defrost sensor unit in freezer didn't help. There's nothing on support page regarding warm freezer.
+Rick Harrington See if this helps click here: th-cam.com/video/5vA8Ksv5kVY/w-d-xo.html
+RepairClinic.com I am having the exact same problem Rick mentioned but on an LG LMX25964ST. Temperature coming out of the blower that feeds air in through the ice maker is right about 32F (fridge staying cold but freezer is not cold enough). This definitely happened suddenly as I woke up to melting ice. Any additional thoughts on troubleshooting?
+David Shorter Repairman diagnosed mine as a bad compressor. New fridge coming tomorrow.
+Rick Harrington Thanks for the additional details Rick!
I have an LG GR409GQ fridge / freezer. The bottom of the freezer is collecting water, which freezes up. I think the defrost sensor needs to be replaced. Does this sound like a reasonable diagnosis? If so, where can I find an instruction of how to fit the part? Also, I note that the outside of the fridge on the left side is very hot. What could be causing this?
This happened to us, and it was just the defrost drain. Once it's clear, problem solved.
They are actually for different model numbers. Your model number is coming up as incomplete. Are you sure that is the entire model number?
