Manufacturer Part Number: 6615JB2005H

The Defrost Sensor Assembly is an OEM part for LG refrigerators. This integral component plays a key role in monitoring the temperature within the refrigerator's freezer section, particularly during the defrost cycle. It ensures that the defrost system activates and deactivates at appropriate temperatures to maintain efficient operation and prevent frost buildup. 

Symptoms of a faulty defrost sensor assembly include:

  • Excessive frost or ice accumulation in the freezer
  • Refrigerator or freezer section experiencing temperature fluctuations
  • Defrost cycle not running or running too frequently

Causes of defrost sensor failure often involve damage from moisture or ice, electrical faults, or degradation over time, which can lead to inaccurate temperature readings and improper defrost cycle regulation.

This OEM LG part is also compatible with Sears/Kenmore.

Questions & Answers

For Lg Defrost Sensor Assembly (Part Number: OEM13315440)

Dave L for Model Number LG LFC25760ST Refridgerator

Last pm I heard the fan in the freezer making noise and saw Ice on the back wall of the freezer. I removed all the frozen food took the bin and tray out. I then used a hair dryer on low to defrost it. I think I spent about 15 minutes. The fan made no noise after that and is running. The problem is now the fan shuts off and I get a beeping warning as though one of the refridg doors or freezer door is open but they aren't. All the switches on the doors are fine and all the lights are off when they are closed. If I open the freezer door and manually press the light switch up the fan will come on when the freezer light goes off as normal.. I actually taped the switch closed and thought it might be the switch. After several minutes the fan turned off and the beeping returned. could it be the defrost sensor? I am not getting any error codes. The compressor and cooling fan run normally and when the freezer fan is running the unit is cold. Thanks!

Dave, Based on the description of the problem this would likely be an issue with the defrost sensor possibly being faulty. Also check for any type of air leaks around the door which could also cause this type of issue.

Hello Dave, Since the defrost sensor kit 6615JB2005H is a relatively low cost part it would not hurt to change it to see if this helps the situation. If this does not correct the issue, there is a real possibility that the issue is caused by the main control board 6871JB1423N.

Hello Jeremy. Sorry, this is a Canadian model and we do not offer any parts for these units.

Hello Rob, You will need to remove the rear freezer wall to inspect the evaporator and any ice that has accumulated. The unit is insulated well enough that the unit will need to be opened and defrosted manually to ensure no ice can contact the fan assembly. The defrost circuit is only designed to remove frost accumulations from a normal cycle and cannot handle unusual ice accumulations such as this. Once all ice is removed and the unit is put back into operation, it should run for 24 hours and the defrost circuit should be checked for any possible problems.

Joe, You will want to pull the rear cover in the freezer compartment and check the frost pattern on the evaporator coils. If there is very little frost or just a couple rows or no frost then this would be a sealed system issue and would need to be have a servicer to repair.

Anthony, The defrost sensor would most likely be the cause of the unit sticking in defrost for long periods of time. If this sensor checks ok then the issue will be a faulty control board.

Hello Bob, If the defrost sensor were the issue, the fresh food compartment would be warming up instead of running too cold. This is most likely a duct assembly issue allowing too much cold to be shared from the freezer compartment. I'm sorry but this part 5209JJ1009D has been discontinued by the manufacturer and no satisfactory substitutions have been provided.

Mike for Model Number lcf2577ost

My LF refrigerator has neither the freezer or refrigerator cooling. No air is being blown into either compartment. The compressor sounds as if it is running. When I put it in test mode 1, the compressor is on and then air is blowing in the freezer and maybe a little is getting into the refrigerator. Test mode 2 is the same situation, but it won't enter test mode 3 (perhaps unit is too warm for that). I have tested the compressor pins for resistance and they are ok. I have tried a new starter relay but since the compressor seemed to come on with the old one, that hasn't made any difference. I say a video that suggested that the pcb panel was defective in a refrigerator when the blowers were only working in test mode, so my last attempt was to replace the pcb panel. The new panel allows the lights etc to work but after kicking the compressor on, it quits in 5-10 secs and I can never even get to the test mode because the refrigerator shuts down and I can only repeat that short cycle. My question is if I had a fault defrost sensor that failed in the on mode, would that be the reason the new panel can't keep the compressor running. The panel seems to be killing the refrigerator operation perhaps because there is a short that is drawing to many amps. Could that have burnt out the old panel but allowed it to function to get to the test modes and the new panel is working appropriately and stopping operation due to short. Very puzzling circumstance. Appreciate any advice before I get a repair person in. Thanks

Mike, If you replaced the main control board on the unit, which is located in the back of the unit and it the compressor is not staying running now then it sounds like you may have received a faulty control board. If the fans are now running and the compressor only kicks on for 5 to 10 seconds then try putting the other overload relay back on and see if it does the same thing or changes. If it does not change would recommend another control board. If this does not correct then it sounds like it could be a compressor issue but would suspect defective board being the cause.

Steven, The Er DH error code is a poor defrost error. It is indicating that Even though it is passed 1 hour since then defrosting, if the defrosting sensor is not over 46 degrees it will cause the error. The things that can cause this would be a faulty temperature fuse, heater failure, drain that is clogged or a poor relay for the heater. With the heater already being tested and it checked good for continuity and the sensor being new, this issue would most likely be caused by a faulty control board.
