LG refrigerator test and reset button

How to reset your LG fridge and run diagnostics with a test button on the PCB board. If you have problems with LG linear compressor refrigerator not cooling or not working at all, you can put it in the test mode with a reset switch on the main control board, which consists of inverter and motherboard. Resetting LG refrigerator may fix some problems, or a number of error blinks on the PCB board will point you in the right troubleshooting direction.

ATTENTION - removing the cover from the PCB board may void the warranty, and exposes electrical components which can be dangerous. If you don't feel comfortable working with electricity, please don't do this test.

Oh my goodness. I was afraid I would have to buy another fridge. I love my fridge. This video helped me fix/reset my fridge! A million thank you's!!

[bassinbillRC]

Thank you. I did this last night on a previous yardwork customer who placed an advertisement in FB marketplace for a freezer not freezing repair. Watched your vid. Removed the service panel, did the steps after viewing 6 blinks of a red LED blinking. I watched for the test step indicator on the fridge's temp display. Fourth push went to "normal operation".
I called her the next morning. I was told her fresh food compartment and the freezer section are working as they should be.

My LLFX28968 stopped cooling after our home AC quit working over 100 degree weekend in Texas. Watched your video, found a code 6: Current Overload flashing after I removed back panel. Ran the self test, everything appeared to be working so I waited thirty minutes then closed it back up. I guess it went overcurrent due to 90 degrees in the house but seems like it's working fine again. Thank you.

As a HVACR tech with little experience with appliances your videos are very helpful in allowing me to learn the correct way to trouble shoot these LG Frigs and not just assume like most techs I work with that it's a bad compressor every single time.

Thank you very much. The water line for the ice maker sprung a leak and the PCB got wet. The fridge stopped. You showed me that there was a reset button and where it was. After things were dry I tried it (using a popsicle stick just in case!) and everything works again fine. Thanks for saving us thousands in fridge and food at the hottest time of the year.

This evening discovered freezer not operating properly but fridge is fine. This will help immensely. Thanks

Great video. I'm a technician and appreciate your emphasis on safety. Great information.

[ashwinimootia]

Thank you so much for the video. You saved me a huge repair bill. God bless you.

Best refrigerator repair videos, period!

Very nice video. Troubleshooting my LG now. Upon first panel opening, the led was blinking but no longer after a power off / on cycle. Will open the bottom half panel to inspect the compressor and related fan work. Fridge and freezer almost at room temp. If compressor with '10 year warranty' then game over as LG was sued for this fault. They charge hundreds of dollars for the labour to install the compressor...if even available with a short lead time. Thanks again for your video!!

It's posts like yours, that make y-tube invaluable. Many thanks.

May 18, 2024 - I have a different and newer model LG fridge/freezer, but it is possible that some of what the host shows in this video may be of some help to me now and in the future. Thanks YourSelf for a very good video. "Live long and prosper!🖖🏻"😊

My LG compressor broke in the 4th year. I'm so glad I still have a warranty up to the 5th year. Never again will I get an LG refrigerator.

This video save me from buying another refrigerator, thank you so much!!!

[petertolentino]

I did the first test then the inside blower ran again. thank you for this video, save ourselves $250 just for a technician to visit or $650 for labor to change the compressor.

Thanks for your video I have a 36" LG and the display would flash a error message after appearing normal after just plugging it in. This for 6 years, then the other day it completely stopped cooling. After watching your video I found the fan wire had fell off. A easy fix. Also the display seems to be working now!

[wakeupisrael]

Very informative and straight to the point. Thanks!

[meneeer]

I found this video extremely helpful. Super simple and effective. It did not solve my problem though. Light M201 in the Inverter section is flashing red 3 times and my fridge is not cooling which leads me to believe that the inverter is busted.

[rosemariegonzales]

following 2nd check, 22 22 appeared on my display panel. What would this mean? thank you so much!

Do-it-yourselfer's, no disrespect to the uploader as he didn't create LG's fault codes, but you can ignore this one folks. Of LG's 8 codes, 6 of them list the PCB as a likely problem. Friends, if you took the 20 main problems we experience with refrigerators, odds are huge it's one of the first 19 and #20 is the PCB. As someone who has repaired everything with a PCB short of the space shuttle for decades, 95% of the time it's not the PCB . I had an LG tech out here who told me I needed a new PCB ($500 +) to repair my ice crush function, the part was $9, labor 15 min and I've had 2 other repairs the techs said "replace the panel" and the fix was never $20.
