I have a LG fridge double door top freezer model no GL-T262QM. the refrigeration compartment is not cooling.

SOURCE: LG model GR-620RW leaking water inside at back top

the drain hole (freezer) is blocked,

SOURCE: lg fridge code er ff does not cool in fridge

ER FF is freezer fan motor failure code. this directs air into the fridge compartment from the freezer room. dead fan=warm fridge.

SOURCE: Brand new refrigerator not cooling

ok what he was trying to say is that the freezer does all the cooling for both sides as nothing in the fride side cools and in order for the fridge to reach its proper temp the freezer should run any where between -0 to-10 then the fan in the freezer draw-es air from the fridge and cools it and circulates to the fridge now i need to know a few things is the compressor running is the freezer fan running do you see any frost on the back wall of the freezer section is the fan running in the back that's near the compressor to cool the condenser coils then i can better advise pleas hold my rating till we are done where did you purchase the unit

SOURCE: Top Freezer section working Bottom Refrigerator not getting cold

I have a side by side jenn-air refrigerator, the freezer compartment working fine and making ice like it should, however the refrigerator compartmant is not cooling, no cold air is felt, I need advise.

SOURCE: Inside top of refrigerator hot light don't turn off.

There is a service bulletin related to this, dealing with deformation / melting of the lamp cover. The fix is to change the lamp wire harness to one that now has a thermal protector incorporated in it (part number 6621JK2003B) along with changing the main PCB board to one that uses a larger relay for this function (part number 6871JB1423N).

In case you want or need to replace the following,
The lamp cover is part number 3110JA1096A and the lamp holder is part number 3034JA1009A

I tried to cut and paste a few photo's, but was unsuccessful. Sorry. Make sure to test that fans and light switches work after part changes.
