So our 2 year old LG fridge/freezer got warm yadda yadda, had a tech come out and look at it. He pulled out the freezer interior panel and said it's sealed system issue. Coils were dry except for about 9" near the very top, which was frozen thoroughly.

However.

The very next day i opened the fridge, and it's COOOLD. The temp gauge I left on the shelf shows that the fridge is cooling to 28'F, and the freezer is down to -8'F. They're set to 35'F / 0'F respectively.

What in the world would cause it to swing in the opposite direction BEYOND what the controls call for? Bad themistor? But how COULD it, if it's low on coolant???

That indicates a sealed system issue but not necessarily a refrigerant leak. It could also be an inefficient compressor or a system restriction. You can diagnose a sealed system problem by the frost pattern. However, to diagnose what the problem is with the sealed system a set of refrigeration gauges needs to be connected to the system. You described symptoms typical to a restriction.
