Hi!
First of all you need to once again defrost your fridge completely. The safest way is to unplug, open both doors, blow fan for minimum of 24 hours, since you may not have defrosted completely previously, you might have ice in addition to frost, ice takes a long time to melt.
Secondly, after you have defrosted for 24 hours or more, plug unit in, set both controls to the middle setting. After unit has run for 24 hours, temps should be 0º in freezer, and 37º in fridge, plus or minus a few º. If you are still way too cold in the freezer as you put it after 24 hours, you also have a bad cold control.
If the problem still persists, please check if the compressor motor is running. If it is humming or making a continuous noise and your refrigerator is still not cooling, there may be a more problems with one or more of several different components. 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 or the condenser fan motor.
Please check if there is fuzzy ice on the back, inside wall of the freezer, then it is a sign of a failed defrost system. A failed defrost system is just one of the conditions that can create this issue. With the box unplugged and still cold, check the defrost heater at the bottom of the evaporator coil with your ohm meter set on X100 to see if you get a reading and check the defrost termination thermostat the same way, with the ohm meter, this part is the gray round disk at the top of the evaporator, but it has to be cold for this test, if it warms up, it will show open. So be sure to check this part while it is still covered with ice. Unless specifically asked otherwise, remember to test with the unit unplugged, or breaker off. Also please check three parts to the defrost system, the heater, termination limit control, and the defrost control.
After following the above procedure, if the issue is still not resolved then you need to check the following things:
Is the condenser fan running and the condenser clean? The condenser is the dirty, icky black coil-thing at the very bottom of your fridge, right above the floor (unless your refrigerator cools its condenser by natural-convection, in which case, the condenser would be mounted on the back of the refrigerator cabinet and you wouldn’t have a condenser fan). If the condenser fan is not running or the condenser is matted up then it is the cause of warm refrigerator.
Is the evaporator fan running? That’s the one in the freezer; you won’t see it but you can hear it. On some models, it stops running when the freezer door is opened, but you’ll hear it when the door is closed.
Does the evaporator itself look abnormal: either
too much frost build-up or
too little? Too much frost indicates a
defrost system failure == easy, inexpensive fix that’s definitely worth doing. Too little frost means either a Freon leak or a worn compressor.
Please do accept this solution and revert for further assistance.
