Both the refrigerator and freezer to warm. Freezer is at 30 degrees and refrigerator at 40 degrees. Not sure what part or parts to order

Hi Mark, thank you for reaching out. Based on our research, it seems that there is an issue with the compressor start relay, part number PS12384298. It attaches to the compressor and helps start the compressor motor. You may need to replace it to fix the issue. We hope that helps!

My LG refrigerator cooling or freezing. I noticed last night the ice cubes were melting in the freezer. The fan still runs and the light comes on when I open it. What do you think the problem is?

Replace Thermistor in back of freezer
Turn off power, remove upper and lower drawers (may need to open upper refrigerator doors to remove large freezer bin,) remove drawer supports (upper and lower), remove rear freezer panel (trick is to loosen 4 screws on fan bumpout to get the panel to come free from the freezer side wall), test thermistor with multimeter (should have continuity or near zero resistance across 2 orange fuse wires) before cutting zip ties, cut zip ties holding Thermistor in place, remove old Thermistor, install new Thermistor, install new zip ties, replace rear freezer panel, install upper and lower drawer supports, install drawers, turn on power, should be fixed if error code doesn't return after 6 hours.

Icemaker quit releasing ice from tray and water was pouring and freezing in ice storage bin
This couldn't have been easier. Two tiny screws in the front needed unscrewed, and then two plastic clips in the middle just had to be popped lose. Finally, you unplugged the power cord. Then, you just needed to reverse the process by plugging the new ice maker in, popping the clips in place, and screwing the two holes back in and turning the whole thing on. Voila! Perfect ice cubes again. And for only a little over $100.

Very bad noise which stopped when the door was opened
The Refrigerator now runs very quite.
After watching several videos I started on mine and found that it was a bit different than any in the videos. However all but the back panel was shown and that was helpful.
The back panel was a bit difficult but a hair dryer seemed to help .
All in all it was a good choice to do it myself as it was done quicker than waiting on a repair man.
