How To: LG/Kenmore Defrost Sensor 6615JB2005H

[@jeff_9074]

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?

[@Nomad397]

Having this same issue. Any notable fix ?

[@jeff_9074]

@Nomad397 No unfortunately.. I ended up buying a new fridge. I found out that when the block of ice forms on the evaporator, it's a sealed system issue. LG was useless in providing any help (considering the class action lawsuit against them is done with im not surprised). In my case since it was 6yrs old, they said they would give me a new compressor under warranty but no labor is covered. You have to use a third party company and the compressor isn't always the problem, or the only problem. It wasn't cost effective to even go down that road considering reading reviews of people who replaced the compressor multiple times and still had issues. I went with a Samsung Bespoke. It's Amazing how much longer my food last now compared to the LG.. the temp probably wasn't consistent, and intermittent issues before finally complete failure. Maybe you'll have better luck than me, and hopefully you're under a parts and labor warranty.

[@Nomad397]

I have been able to find the defrost sensor like in the video for the freezer section but not for the refrigerator section. Purchased in 2017 I have the LFXS30796D which was not included in the class action. Freezer section rarely has an issue staying cold. I guess lesson learned never buy an LG refrigerator again.

[@jeff_9074]

@Nomad397 mine was the same way. The freezer section would still keep things frozen, but the fridge section would intermittently get warm out of nowhere. Sometimes, unplugging the fridge for a few minutes would work.. what I was told happens is, as the compressor breaks down, the debry can form a clog in the three-way valve or filter dryer.. also, I was told sloppy assembly of the sealed system at the factory resulted in Flux splattering on the evaporator, which resulted in very tiny holes over time, causing slow leaks of freon. The usual fix is to replace the entire sealed system (evaporator, filter dryer, compressor and three way). There are videos out their on KZbin that demonstrate using a bullet valve to peirce the freon line, and hook up a guage to check your freon level. It could possibly be low on freon due to a leak. Note: opening up the sealed system however will jepordize your warranty. So be sure you no longer want to deal with LG before doing so. I wasted a lot of time trying different things and fighting with LG to try and save a 6yr old $3k fridge (now paperweight) without luck. I would have replaced the sealed system myself.. the problem is no one wants to come out just to recover the freon (at least in my area). And the machine is very expensive to purchase. Most small repair services won't touch sealed system issues either. And most won't even bother with LG issues.. My fridge was purchased in 2016, I think they were having compressor issues for a while (using the same linear compressor in their models) before a class action lawsuit was formed from so many broken fridges. My final thoughts to you are, on the back of the fridge, there is a removable panel. Once removed, you have access to the main board. There, you will see a green light. That may give you some kind of blinking code to reference. Also there you can run a diagnostic by pushing the little button. It will run the fans, the defroster, and the compressor at different times (also a youtube video on it somewhere). I believe if a fault is found during the test it will show a code on the front door where it usually displays the fridge set temps (not actual).

In your video there are two black wires that go to a separate plug. On my LG unit those two black wires come from the condenser and are inline with brown wires from the sensor and blue and black wires to the plug. Should I just cut and splice the new sensor in?

[@nabaddame5726]

What's the procedure to test this sensor to confirm its actually faulty?

Hi I have a LG gr-l218stsl not cooling, I have noticed ice build up at the top near defrost thermal fuse on freezer condenser. I'm wondering if it is worth replacing the defrost sensor and thermal fuse before I go ahead and regas it? Please Help

[@cadetw46]

Can you turn the freezer into a manual defrost type by removing the sensor?

[@OMGWTFLOLSMH]

I was hoping you were going to demonstrate how to test the sensor.

[@justincarter8366]

I have a kenmore 79569009900 and looks just like the same evaporator assembly and defrost sensor. I get an error code 567 which means its the sensor or the heater. Evaporator was frozen over and I was wondering how often is it the heater or the sensor?

[@thomassankara2857]

Hi, I want to order the temperature sensor for the refrigerator side, where do I locate the refrigerator side sensor? Thanks.

[@joeydelmarsjr.646]

if the sensor is bad, would that make the coil to freeze up and defrost and water to drip to the floor?

[@appliancepartspros]

It is possible that could cause an issue. Are you able to hear the fans running?

[@joeydelmarsjr.646]

@@appliancepartspros yes it does maintain temp 0-10 freezer and 35-40 produce side. But every 3-5 days i have i see water on the freezer side on the floor. its a side by side

What is your model number number? How much water do you see? Is in inside the freezer or on the actual floor?

[@brucelikuan2475]

Samsung RS263TDPN refrigerator, Freezer wont cool, fridge side is working, no frost formation on freezer or fridge coils. Sir what do you think the problem is?

[@clarenceworley2855]

Would the Thermal fuse/Defrost sensor located in the freezer section cause the coils in the fridge section to ice/frost up as well? For a week or 2 i was receiving an error code "R DH" so i powered the fridge off and powered it back up, only to have the error return 2 days later. After the third reset, I stopped receiving the error, but noticed the rear inside of the fridge compartment freezing up. I have powered the fridge down and let the ice melt off of the fridge coil (no ice on the freezer coil) but I am not sure which defrost sensor i should be replacing. (Is there one on the fridge coils too?) Thanks

[@appliancepartspros]

If the fuse / defrost sensor failed the defrost cycle would not work and the evaporator would freeze up.

[@ryanworthington6346]

I have a Kenmore with a bottom freezer. When I power the fridge on everything works. After a little while the evaporator fans shut off while everything else keeps running. There’s zero ice or cool air. Why do only these fans shut off?

[@fasilkefelew8492]

[@cooldbz12mach1padilla]

[@ImAbum69]

I have LG lsxs26366s. Every 1-2 days my freezer gets up to 20 degrees Fahrenheit for 20-30 mins then drops back to 0. Do you think it's a failed defrost sensor not shutting down the heating element? BTW - can you point me to the right defrost sensor for this model. Thanks.

[@jaber4life]

That’s normal

[@spamh3591]

How would you test the sensor in a room that is 72 degrees Fahrenheit

[@Jeepjones85]

OJ simpson Simpson mix up water and ice put the sensor into the ice water and read the ohms with a good meter, find a ohm temperature chart on line and see if the sensor is out of range, temperature will be a constant in the ice water around 33-32°

[@austincollins2951]

I have a different issue where the defrost coil is constantly heating, preventing the freezer from cooling. Is there a way to reset the defrost timer on this type of refrigerator, or something else? I tried the part in this video and didn’t seem to change anything. Any help would be appreciated!

I have to remove the cover and put a couple pots of boiling water to thaw it out. There are no other problems, just this one. I was told it could be the timer or thermostat. If this is true, how much does it cost and, is it easy to remove? GOD bless and thanks a lot. Awesome video.

Useless video. Just showing changing the sensor . Not showing values to detect fault . How do you know it was bad if you haven’t tested it.

[@appliancepartspros]

If you need to test the part you will test it for resistance. The resistance should show 8.9K Ohms or more for temperatures colder than 30°F or from 6.2K Ohms to 8.8K Ohms for temperatures between 40°F to 31°F.
