I noticed there were ice forming in the freezer section and cleaned it out and now it seems the freezer is ok but the fridge part on the bottom is not keeping things cool. I also noticed there is some water that occassionally builds up on the bottom of the fridge section. Is that coming from the freezer section? Maybe I stuffed my freezer section too much or there's not a tight seal?!? Do I need to get a new compressor? What happened? Agggh!
Thx for your help in advance...
Hi softwaredude with an LG GR-727R refrig. The occasional build up of water on the bottom of the fresh foods sections tells me that the refrig is going through it's defrost cycle, but that the defrost drain is plugged. If you take the back off the refrig. you will see a plastic tube about 1/2 inch diameter with a few ribs on it going from the top of the compressor compartment to the bottom, which is a defrost water holding / evaporating pan. Look to see if that tube is plugged. If not, it is plugged further up, most likely where the defrost water drains off the evaporator (that the coils behind the freezer wall that do all the cooling). Take that back panel off and use a hair dryer to melt all the frost off. The frost is blocking air flow from the freezer section to the fresh foods section, thus poor or no cooling in the FF section. You should be able to spot where the defrost water is suppose to drain. If the water is not draining out, use a turkey baster with hot water to flush out the drain.

If there is no cooling at all on the fridge section but the freezer works then it is confirmed that the compressor and gas pressure is OK. Now shut off the fridge and leave it powered off while you clean and check the evaporator for frost. If frost is seen it is a good indication as the compressor is working with sufficient gas within.
Now after about 6 hours plug in the fridge to start. Observe cooling to happen in about one hour and ice to from under three hours.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge.
However if ice forms in the freezer then observe the fridge for about 24 hours for cooling to continue and the fridge to cut off . If not the auto defrost timer, or the thermostat must be checked. Frost formation without defrosting could block the air flow and so shut the air passage to the fridge. Also the blower fan must work and if this is not working then the fan can be faulty. Also a fault on the control unit is a suspect to non functioning of any one of these components.
If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
So try this test using a multi-meter on the defrost timer and the thermostat and make your observations so that we come to the solution.

When the freezer section gets cold and reaches its required cooling temperature, after that the frost on freezer section starts defrosting and the cooling fan in the freezer section blows this cool air from freezer to fridge. But if the defrost cycle does not start then over ice will get collected on freezer ventilations and that will block the air passing section from freezer to fridge, so the freezer gets cool but fridge section does not cool.

Its defrost problem. Try manual defrost by unplugging the refrigerator from main power outlet for 24 hours then reconnect it and check, if the same problem is noticed again,. If yes then its defrost board problem. The defrost board located in the back of fridge section. You can get required parts from www.repairclinic.com or from online sears part site. ------------- Thank you.

Hi MNTECH! Thanks for your advice. I was able to open the bottom back part and as you mentioned, I found the plastic tube. It was dry. But I can't seem to get the top back off. Looks like it has that foam insulation stuff in it. I am afraid if I force it open, I could bend the metal back sheet.
I did have another look inside and I noticed there is some water that is may be dripping in the back from the bottom of the freezer compartment. I suppose perhaps I can take off the plastic housing (there is a temp control) and see further. The upper freezer compartment appears to be frost free now but still question whether the bottom fridge section will get cool.
I unplugged the Fridge and left it over night. All the ice melted and so far it seems like the bottom fridge part is cool again. Thx MNTECH!
BOTTOM FREEZER KEEPS GETTING BLOCKED OFF WITH FROOZEN ICE PREVENTING AIR FLOW. INDOOR FAN WONT START UP AND REFRIGERATOR STAYS WARM.
