First check that the cooling vane and air ducts are not clogged or dusty as this can also cause thre compresssor moto to run constantly for extended periods. f these are OK then it sounds as though either the thermostat has become faulty and needs replacing or the control module has a fault and will need replacing. As it is cooling OK this means thatthe compreassor is working OK and there is most likely no leak in the coolant gas.

FREEZER COOLING OK BUT FRIDGE LOW COOLING


Remember that most all refrigerators only have cooling to the freezer... the refrigerator depends on stealing some of that cold to be cool, so here's my top 3 guesses...
Cause 1 The defrost heater is defective, so frost accumulates on the evaporator coils, and the coils will become plugged with frost causing the airflow through the coils to be restricted, and the refrigerator not to cool. Check the evaporator coils to determine if they are frosted over. If the evaporator coils are frosted over, test each component of the defrost system after clearing any restrictions to the cooling fan and defrosting with a hair dryer.
Cause 2
The evaporator fan motor draws cold air over the evaporator coils and circulates it throughout the freezer. If the evaporator fan is not working, the freezer or refrigerator will not cool adequately. To determine if the evaporator fan motor is defective, try turning the fan blade by hand. If the fan blade does not turn freely, bench test it for function and use a multimeter to test the motor windings for continuity. If the windings do not have continuity, (very odd) replace the evaporator fan motor.
Cause 3
Damper Control Assembly The air damper control opens and closes to let the proper amount of cold air into the refrigerator compartment. If the damper does not open properly, it won't let enough cold air into the refrigerator. Check the damper control to determine if it is broken or stuck closed or that an inadvertent bump has shut it off to the refrigerator compartment

LG 262SQA Model fridge cannot cool


That does not look like an LG model number, but regardless, it sounds like the defrost system is not working, allowing frost to build up and block air flow over the cooling coils in the freezer (where all the cooling for the entire refrigerator takes place). Take back panel off inside freezer, melt frost / ice with a hair blower. Test for continuity through defrost heater and replace if "open". If it was OK, problem could be deftost control, or as simple as a door not fully closed at some time, allowing excessive frost build up.

Refrigerator and freezer not cooling sufficiently, problem started without known cause, continues, have not tried to fix it


If the refrigerator isn't cool, you need to answer some questions, then see if the compressor is running.
First, answer these questions:
Is the refrigerator completely dead? If so, see “It's stopped completely.”
Is the thermostat knob turned to the proper setting? If not, reset it.
Next, see if the compressor motor is running
The compressor is a football-sized case with no apparent moving parts. It's on the outside of the refrigerator at the back near the bottom. If it is humming or making a continuous noise and your refrigerator is still not cooling, there may be a more serious problem with one or more of several different components, we recommend contacting a qualified appliance repair technician for further help.
If the compressor is not running but you do have power to the refrigerator, there may be a problem with one or more of these:

The compressor

The Thermostat

The overload, relay, or capacitor

The defrost timer

The condenser fan motor

Cooling is poor
For an overall understanding of how refrigerators should work, read about refrigerators in the How Things Work section of our website. A refrigerator or freezer that is cooling, but cooling poorly, may have a problem in one of several areas:

Poor cooling is often the result of a heavy frost build-up on the evaporator coils or a condenser that is clogged with dust, lint, and dirt.
Evaporator coils
Poor cooling is often the result of a heavy frost build-up on the evaporator coils. You can't see these coils without removing a panel on the inside of your freezer. A sure sign that there is a build-up is the presence of any frost or ice build-up on the inside walls, floor, or ceiling of the freezer. Such a frost build-up usually indicates a problem in the self-defrosting system or damaged door gaskets.
The refrigerator is supposed to self-defrost approximately four times in every 24 hour period. If one of the components in the self-defrosting system fails, the refrigerator continues to try to cool. Eventually, though, so much frost builds up on the evaporator coils that the circulating fan can't draw air over the coils. There may still be a small amount of cooling because the coils are icy, but with no air flow over the coils, cooling in the refrigerator compartment is quite limited.
Here's an inexpensive, though inconvenient, way to determine if the problem is with the self-defrosting system. Remove all of the perishable food from the refrigerator and freezer, turn the thermostat in the refrigerator to Off, and leave the doors open for 24 to 48 hours. (Be sure to have several towels ready in case the melting frost and ice causes the drip pan to overflow). This allows the refrigerator to defrost "manually." When the frost and ice build-up has completely melted away, turn the thermostat back to a normal setting. If the refrigerator then cools properly, it indicates a problem with one of three components in the self-defrosting system:
The defrost timer
The defrost thermostat (also called the bi-metal switch)
The defrost heater

to check these components .... please refer to my solution in the below link....

http://www.fixya.com/support/t4189238-defroster_not_working_checked_defrost

If it still does not cool properly, there may be a problem with the refrigerant level or the compressor. You may need to consult with a qualified appliance repair technician to further diagnose the problem
Condenser
Self-defrosting refrigerators all have a set of coils and a cooling fan, usually under the refrigerator, that need to be cleaned regularly. If these coils get coated with dust, dirt or lint, the refrigerator may not cool properly. The coils may appear to be a thin, black, wide radiator-like device behind the lower kick-panel. To clean them, disconnect the refrigerator from the power source, use a refrigerator condenser brush (see the Appliance Accessories section) and your vacuum cleaner to clean the coils of any lint, pet hair, etc. You may not be able to get to all of the condenser from the front, it may be necessary to clean the remainder of the condenser from the rear of the refrigerator.

Refrigerator cooling to 59 degrees in non freezer compartment


If the fan is running you more than likely have a defrost problem.
Look at the back wall of the freezer section if it is frosted up. it's not defrosting. This keeps the air from circulating through the refrigerator section.

Freezer works fine...refrigerator section


Have you noticed more frost in the freezer than usual? It sounds like you may have moisture building up and freezing around evaporator fan. The fan blade hitting ice will cause the buzzing until it stops it completely or the evaporator clogs with frost and blocks airflow. If you have frost on food in freezer, check the door seals and make sure nothing is keeping doors from closing completely if you release them about 6" from cabinet.
