Carrie October 28, 2019 for Model Number LFX31925ST My refrigerator won’t go below 50 degrees. Freezer works great. I cleaned the coils in the back and made sure none of the vents were blocked. I thought I should feel air flow near the vents but there’s nothing. I tried to listen for the evaporator fan in the freezer but didn’t hear anything. No louder noises or clicks from the compressor. Thank you.
1 Answer Carrie, the evaporator fan will need to be tested at the main control in the back of the unit. At the connection CON6 of the main control, pin 1 (gray wire with black probe of meter) to pin 2 (blue wire with red probe) will need to be tested for 12VDC. If there is not 12VDC, then the main control has failed. If there is 12VDC, then it will need to be tested from pin 1 (black probe) to pin 3 (yellow and black wire with red probe) and the voltage should read between .1 to 4.9VDC. If the reading is not within this amount, then the fan motor has failed. The refrigerator sensor should also be checked at the main control at connection CON7 with the refrigerator unplugged. At 50°F, the resistance should read 19.5K Ohms when testing the two white wires at pins 15 to 16. The REV number for this model will be necessary when replacing parts as this can change what part is used. Read More...
Mike September 06, 2019 for Model Number LFX31925ST Coils on my evaporater have frost, but the fridge is warm and the freezer is warm.
1 Answer Mike, Check to see if the evaporator fan motors are running. Also, check to see if there is an issue with the defrost circuit. Check the sensors, the defrost heaters and the defrost bimetals to see if this would be the issue. Read More...
Sebastian August 19, 2019 for Model Number LFC23760SB My freezer is not maintaining the items in a frozen state. Does make ice but slowly, like one tray per day or two. The temperature in the non freezer section is also not as cool as normal. I set the setting to max (7) for both and that did not make a noticeable difference. We did just come out of a three day heat wave (100 degrees). I don't have air conditioning in the house. The weather has returned to normal now at 82 degrees and perhaps refrigerator is working a little better. The refrigerator is about 10 years old. In the past, this condition has happened several times over three years but each time returned to functioning properly. Does the refrigerant (R134A) need to be reloaded/recharged?
1 Answer Sebastian, the ambient temperature can impact the performance of a refrigerator and cause it to not cool properly. Once the ambient temperature, where the refrigerator is, reduces to 89°F the refrigerator will be able to operate properly. The freon would not have to be recharged unless there is a freon leak, and in the case of a freon leak, a certified technician would be needed for repairs. Read More...
Wei July 19, 2019 for Model Number 795.78306.800 Hi Sir or Madam, My refrigerator works intermittently. When it stops working, I can unplug the power cable, wait a few minutes, replug it. Then it will work for a while. But then it will stop working. When it stops working, both the refrigerator and the freezer become warm. Food will thaw. How to diagnose this issue and which part to buy? Thanks. Mine is a Kenmore. I believe it is made by LG. But not super sure. Wei
1 Answer Wei, based on the information that has been provided, the most likely issue is going to be with the main control EBR41531305. As the unit can be placed into a hard reset and operate properly for a time, it is unlikely that there is a failure with the temperature sensors or compressor. It would also be unlikely that there would be a fan issue. Voltage checks can be done to find what the main control is sending voltage to, but based on this information, there would most likely not be any voltage sent to any of the components that are used for temperature regulation.

Peter M June 29, 2019 for Model Number LFX25974ST My LG two-door refrigerator has suddenly stopped cooling, freezing, or making ice. The fans are running, and I don't believe the compressor is dead (no clicking or other weird noised coming out). I'm trying to figure out if it could just be the thermistor (yay -they're dirt cheap, and easy to replace), but I don't know how to test it without destroying it by cutting the wires attaching it to the refrigerator. Is there only 1 thermistor in the refrigerator? The one in the cooler section is easy to find, but I don't see anything like that in the freezer section. Any help that you could provide would be greatly appreciated. (You guys helped me fix my LG washing machine a couple of years ago).
1 Answer Peter, If the compressor is running you will have frost on the evaporators. You will need to pull off the rear covers and check the evaporators. If the compressor is running and no frost you have a compressor that is running but not pumping the refrigerant. You would need a compressor and a refrigeration technician to finish the repair. It doesn't matter what the thermistors read or if fans run, if that compressor is running you should have frost so pull those covers off and see what you find. Read More...
Russ June 03, 2019 for Model Number 6500JB2001B (AP4441492) How do I replace the 6500JB2001B sensor in my LG 4 door French Door Refrigerator? I have a Model # LFX28968ST-00. My refrigerator is slightly different than Model Number shown in the repair video. My refrigerator does not have the grill at the top of the refrigerator that is shown in the video (see image in link below of what I DO NOT have. http://bit.ly/Sensor_LG_LFX28968ST00 I am just lost. I cannot locate where this sensor is located in order to install the part (6500JB2001B). Any help would be much appreciated,
1 Answer Russ, Look for a cover in the top left corner. If you can't find it you may need to pull the rear cover and check there in the air tower. Read More...
Jenna Grant March 09, 2019 for Model Number LFXC24726S/00 I ordered a thermistor for my refrigerator. Part number 6500JB2001B and I can’t locate it in my refrigerator so I can replace it. Can you please help tell me where I can find it?
1 Answer Jenna, The thermistor would be located under a small grill on the ceiling of the refrigerator compartment. You would use a flat blade to pop the grill off. Read More...
Rebecca January 17, 2019 for Model Number 795.74025.411 I ordered a sensor for my Fridge. The part I was given was 6500JB001B. I am unable to locate where this sensor goes. I have been sent videos that show it inside like it was easy to get to but my Model Fridge is a Kenmore Elite 795.74025.411 and it's different. Where is this sensor please I am desperate and need to fix this fridge? Thank you
1 Answer Rebecca, based on the parts diagram, the thermistor should be located in the back panel where the fan is. If you pull out all the shelves and drawers, you will be able to access that back panel by removing the screws from the bottom of the panel as well as two that are hidden behind plastic covers where the metal rail is on the panel. As you are removing the back panel, you will notice a little "grill" at the bottom of the panel, this is where your thermistor should be located. Read More...
Tim December 12, 2018 for Model Number LFC28768ST I have error code er rs on refrigerator. Looked it up and it says to replace refrigerator sensor. Where is this sensor located. Also is there one located in the freezer also. And where would be located. Thank you for your help.
1 Answer Tim, If you look at the top of the refrigerator or freezer compartment there will be a small oval grill that you would need to use a flat blade screwdriver and pop out from the ceiling. The sensor will be located under this grill. Read More...
Kelly Wagoner November 06, 2018 for Model Number LMXS27626S-01 How do I replace a 6500JB2001B sensor in my LG 4 door French Door Refrigerator
1 Answer Kelly, This thermistor will be located at the top of the refrigerator compartment under a little oblong cover. You use a flat blade screwdriver to remove the cover and then pull the old sensor down. You will then need to cut the old sensor probe off and splice the new probe in place using butt connectors.
