ltcs20020 Fridge Not cooling, freezer works

[MikeD123]

My fridge is not cooling but the freezer is working. The fridge is brand new. We moved it to our garage while renovating our kitchen. I've checked to ensure the vents aren't being blocked. I tried to reset the temp but it does not work. I've unplugged and plugged it back in too. The temperature lights reset to something else after I set the temp. Please see attached pic where the two lights on the left disappear after I reset the temp. 

Thank you in advance!

If the freezer is working and the vents are clear then it should be working unless it has an electronic damper that's stuck. What temp is the freezer at?

Take a full picture of the inside of the refrigerator compartment could be you have too much food blocking air circulation. You'd be surprised how food placement affects cooling. Normally it goes from top shelf to doors then everything else underneath top shelves. Too much food on top shelf and door shelves packed result in varying temperatures and possible freezing on top shelf.

I've unplugged it and plugged it back in. It seems like it is a little colder since the initial post.

Another poster spoke of the FF door sensor not always sensing door shut.  He taped a small magnet on the door to trigger it better.  Check by putting a cell phone inside with video running, shut the door.  Review the video to see that light goes out.  Or check the CON8 / GREY WIRES on PCB.

Also when switch doesn't work the evap fan won't spin enough to keep ice from the FZ to FF channel, so that may need to be steamed.

Headed out to one today, same symptoms, will be checking on this also.  

UPDATE:

  This ONE YEAR OLD fridge, the evaporator fan motor has failed!  These style motors are failing at an alarming rate.  It's the smaller type.  I am finding that they are failing at about the 1 year mark.   These are showing up in all newer LG's.  The Evap motor, Ice Fan AND the condenser motors are all failing and are made by various mfgs.  Only SOME of the models have the service bulletin (Fan shipped without lubricant) , but they are failing everywhere.  This is a photo of that evap motor and a  condenser fan I replaced last week.
