Ciaran January 20, 2025 for Model Number LFC23760ST Fridge appears to be working as it should be but there seems to be a louder than usual click as the compressor turns on and off. This started happening a couple of months back. I understand that the start relay should be clicking on and off but I don't recall it being so loud. Could it be that the relay is going bad and would this be the correct part to resolve for my LG LFC23760ST?
1 Answer Ciaran, The compressor start device part numbers are Compressor Overload Protector 6750C-0005P and Compressor Start Relay 6749C-0014E Read More...
Lorenzo T December 30, 2024 for Model Number LFX25960ST Why this refrigerator stops for about two o three days and start for two o four hours and stop thanks in advance
1 Answer Lorenzo, If the compressor is starting and running then it is not likely to be a start device. Based on the information provided you could have an electrical or electronic issue. Read More...
Dan August 05, 2024 for Model Number 795.75196400 My fridge and freezer won't maintain temp. The condenser coils seem reasonably clean; no frost on evap coils; the condenser and evap fans appear to be functional (no apparent mechanical issues, since the fans spin I haven't checked for any potential electrical issues with their motors). I think the compressor is running (though can't confirm); it seems quiet, though feels warm. After reading online, I'm wondering if the start relay, capacitor, and/or overload protector could be the culprit. Thoughts? How can I tell if the compressor is bad? Is it more likely one of the three aforementioned electrical components (if so, which)? Thank you!!!
1 Answer Hello Dan, thank you for contacting APP, It is possible that the Start Relay 6749C-0014E, Start Capacitor 0CZZJB2014L, or Overload Protector 6750C-0005P has failed and I normally suggest testing or replacing these components before looking at replacing the compressor. You can test the compressor start and run windings for Os resistance, but these may read in range and the compressor be locked up and unable to start. Read More...
Roger April 26, 2024 for Model Number LMXC23746S 01 I cannot seem to get the freezer nor the fridge to cool down. I checked all fans and they all work. The system kicks out a "22" code which seems to be the start relay. Is the part number for this: AP5949339 or 6749C-0014E?? How can I tell if it is the start relay or the compressor itself?
1 Answer Roger, the display showing 22 would indicate that the test button was pressed twice on the control and a specific test is occurring. During normal operation, if the compressor vibrates but the unit does not cool down, there is a sealed system failure. If it does not, there should be a red LED on the main control that will flash if the control has identified a compressor failure. If there is not a flashing light, the main control CSP30021034 would be the most likely cause of failure. Read More...
Teresa Macrobbie October 04, 2023 for Model Number 795.78556800 My refrigerator has stopped coolin. I hear clicking and maybe the fan going on and off. Could this be the compressor relay start device? If so which part would I need. Thanks
1 Answer Teresa M, Your model has an electronic board so the relay on the board may be what is clicking or the compressor could be the issue. Read More...
Bruno August 17, 2023 for Model Number LFC23760ST Hello! We have a 14 year old LG LFC23760ST with a freezer that is not cooling down enough (I changed out the motherboard about 7 years ago). I cleaned out the coils and checked the compressor, which feels and sounds just fine. All fans appear to be working. No noise or vibration from anything. Minor frost on the back panel of the freezer but was able to brush it off with my hand. I'm thinking of replacing the run capacitor and compressor overload protector. I wanted to confirm part numbers before ordering. Any thoughts on what the issue could be is appreciated. Thank you for your time.
1 Answer Bruno, You will need to pull the rear wall in the freezer compartment and check to see what the frost pattern looks like on the evaporator coils. If there is heavy frost then this will be a defrost issue in which you will want to test the defrost heater and defrost sensor to make sure that they are good. If they are good then the control board would be faulty and need to be replaced. Read More...
Walter September 08, 2022 for Model Number LFC25760ST The refrigerator no longer cools. I powered down for 45 Minutes. Powered back up. The internal lights come on. I heard a faint one click. Compressor did not come on. I can hear the fan run. I understand that this could be a start relay or the compressor. Any input will help. I tried the above a few times. The same result. Thank you,
1 Answer Walter, the start relay 6749C-0014E can be tested for resistance and it should measure between 5 to 8.6 Ohms when testing the side where the compressor pins plug in. If the resistance is not within this range, it would need to be replaced. If it is within this range, the compressor TCA35931726 would be the likely cause of failure. Read More...
Mark April 16, 2022 for Model Number Lfxc24726s/03 I have an LG refrigerator and I think the relay start is bad. Can you give me the part number so I can order? Do you have overnight shipping?
1 Answer Mark, This model does not use a start relay. It uses an inverter which is part of the main control board. But to determine the issue you would want to consult the tech sheet and check the resistance of the compressor windings and verify the voltage to the compressor. The tech sheet may also have compressor diagnostics outlined as well. Read More...
Krunal February 23, 2022 for Model Number LFX25976ST/00 Is this model LG refrigerator has compressor start relay? Because i can't find near the compressor.. Thanks
1 Answer Krunal, This unit does not use a start device and is run by an inverter board EBR64173903. Read More...
Michael November 14, 2021 for Model Number eqylibrium001a@aol.com the compressor on my Kenmore elite model # 795.71052.012 does not seem to work. what compressor start relay can I use? as I do not see the correct part here. Thanks!
1 Answer Michael, This unit does not use a start device and has an inverter built into the main control board that will operate the compressor. Test to see if there is power getting to the compressor and if there is then the compressor will be the issue. If there is no power to the compressor then the main board would need to be replaced.
