Maggie October 07, 2022 for Model Number LFC25776SB Having the issue where the fridge and freezer are both warm. Appears the fan to cool the interior of both will not kick on. If you go through the test switch, all items appear to work (fans, compressor, etc.). Not sure if it's a sensor or one of the boards.
1 Answer Hello Maggie, Since you can force everything to work but it will not work on its' own, this is most likely an issue with the main control board EBR67348002. Read More...
Pj August 22, 2022 for Model Number 795.71023.010 Thanks for the help on this. I was about to test the inverter, plugged it in and it started to work like it's supposed to. Something like this happened a couple years ago when the fridge was left ajar when we went out of town for the weekend. I don't know if that was the case again, but seems coincidental. Is this a safety shut down? I'll keep an eye on it for now. If you could please let me know that would be great. I've attached the previous correspondence for reference. Fans are running, no compressor. Compressor was replaced 9 yrs ago after only being in service for 2 yrs. Relay RY201 on the control board is ticking like a clock and will not stop. LED not illuminated at all. Read a couple of other questions that were similar but need some more info. What series of checks can made to diagnose. I don't want to buy PC boards and not be the problem I am sure you understand that mess. Pj for Model Number 795.71023.010 Answer PJ, You can test to see if there is 120 Vac to the inverter board coming off the main control board. If there is not then the main control board will be the issue. If there is then the inverter would be the most likely cause. Whichever board is making the clicking will be the most likely cause for this issue.
1 Answer PJ, it is possible that it could have been a temporary glitch. However, the only sure way to identify the failure would be testing during the state of failure or identifying an error code. Read More...

James October 11, 2020 for Model Number Lmx25964st/00 If the coils are only frozen on the top half, could it be low on freon? I replaced the defrost control & the temperature sensor. The fridge gets down to temperature, but the freezer will only get down to 20 -25 degrees
1 Answer James, This would most likely be a leak in the sealed system and would need to have service to repair the unit. Read More...
Roger August 24, 2020 for Model Number LMX25964ST/01 The freezer and the refrigerator feels cool but the freezer does not freeze. I pressed the test button and 22 error is displayed. The error code means there is problem with the Compressor Start Delay, Tried looking up the part and it does not show. Contacted several part vendors and again the Compressor Start Delay does not show separately. Is the part come together with the compressor or Could the problem be with the PC Assembly Sub?
1 Answer This is most likely a control or compressor error, as this model does not have a compressor start relay. Read More...
Jessgrand March 14, 2020 for Model Number LG LMX25964ST/01 Purchased unit 2011. Technician replaced the original compressor FC75LBNA 60mhz with FLB075LANA 53mhz and also replaced the capacitor from 18mfd to 10mfd. After the repair, the temperature average fridge/freezer to 40/20F(fahrenheit). Later, technician added freon and temperature averaged 36/15F. Freezer never reached zero F or lower. Default settings 33/minus 6F. Also, there was ice build up on the copper tubing between the compressor and evaporator and after about 8-10 hours ON, unit defrost stays OFF for about an hour, temperature goes up 40/27F, then turns ON again for 8+hours then defrost, getting the same temperature averages. I am happy with the fridge temperature but not the freezer. That's the cycle. The condenser coils cleaned, both condenser fan and freezer fan running and even applied petroleum jelly to door gaskets to keep a good seal. I suspect the freezer temperature sensor that is causing the freezer not getting the zero or less temperature. I do appreciate it very much for your help. Thank you.
1 Answer Jessgrand, if the compressor is operating the entire time that the unit is not in defrost and the freezer is not reaching proper temperatures, more than likely there is a freon issue. The compressor should not run the full 8 hours unless either there is a frost build up on the evaporator or not enough freon passing through the evaporator. Based on the information provided, it sounds like it would be the freon, the tubing running from the compressor to the evaporator should not have a frost build-up. Read More...
Joe January 25, 2020 for Model Number LMX25964SS My compressor will not come on but the fan does. Could this be caused by the start capacitor ?
1 Answer Joe, the inverter board EBR64173903 would need to be inspected for a flashing LED as this can tell quite a bit about what's going on. If there is not a flashing LED, then the inverter board would need to be tested for 120VAC at connection CN2, and if there is voltage, the inverter is bad. If there is a flashing LED, this will indicate a failure. If the LED is solid, then there is a communication failure between the main control and the inverter which can be tested for a pulsing DC voltage at connection CON201. If there is a pulsing DC voltage, the inverter has failed. If there is not a pulsing DC voltage, the main control EBR67348009 has failed. Read More...
Joe January 24, 2020 for Model Number lg LMX25964SS /00 Good morning, I had a question about my LG refrigerator. What does it mean when the compressor does not come on?
1 Answer Joe, the compressor not running can be caused by several things. There will be a control board next to the compressor that can be used to identify if the compressor has an issue. If the control detects an error, the LED will blink in a pattern that can be used to identify the issue. If there is not a flashing LED, then the control has not detected an error and the thermistors and main control would need to be tested to identify if there is either a temperature sensing issue, or a signal issue to the compressor control.

Jose H February 20, 2017 for Model Number 79574025410 My refrigerator leaking water on the battle off refrigerator. I removed the cover and found the evaporator cover with ice. Not sure what could be the problem.
1 Answer Jose, You will want to check the defrost heater and the defrost sensor to make sure that they are good. The sensor part number is 6615JB2005S, and the element is MEE62225112. Test the parts for continuity. If both check ok then the issue will be a faulty control board. Read More...
Gil February 12, 2015 for Model Number LFC25776SB I've been looking for a main circuit board for my LG refrigerator model #LFC25776SB. The number print on the board is # EAX64121503. I have not had any luck finding it.
