FREEZER /FRIDGE NOT COOLING: Optimum refrigerator temperature at or below40° F(4° C). The freezer temperature should be0° F(-18° C). Check temperatures periodically. Appliance thermometers are the best way of knowing these
Check ur cold control thermostat, ur thermistors in both fridge and freezer ( they should be checked for both ohms and for amount of current being put out as per ur model ), ur air flow vent from freezer to fridge.( to make sure it opens and closes without any restrictions) On thermistors check for A close circuit and amount of ohms not just an Ohm reading. As per ur model. Most should atleast show 1200 ohms. Also Check door seals for leakage.Evaporator coilsPoor 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.
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.
FAN check to see if it is operating or restricted A fan that is not blowing or restricted will not circulate the cold air properly.
Often, the first thing that folks do when their refrigerator starts to feel warm is turn both controls on the coldest settings.This is exactly the WRONG thing to do.Turning the cold control to the coldest settingwillkeep the compressor running longer and make lots of cold air.
But turning the air door to the coldest settingclosesthe airway to the food section. Lots of cold air is made, but most of it stays in the freezer section, and the food section actually getswarmer.
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 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.
May also need to check the defrost timer, u can get by and test manually by placing a small screw driver into the tiny slot or hole underneath the timer and turn slowly clockwise till u hear 1 click. this will engage ur defrost cycle in about 15 minutes u should be able to come back and feel the heat in freezer as it melts the ice providing ur terminator is not bad?
Another way to test it is with a multi meter. Remove timer it from fridge and you will see 4 prongs numbered 2,1,4,3 in that order. Place ur meter prong on prong 1 & 3 (if your fridge has a capacitor wired in series with the windings, then u check for micro fares rather than OHMS) If u cannot confirm this test, still try the next.
Take ur meter prong and connect to prong 1 & 4, it should read resistance or ohms ( closed) now remove prongs and place on prong 1 & 2, this should now read infinity or open (no ohms) now take a small screwdriver place it in the tiny hole or slot under the timer. Turn it clockwise slowly till u hear 1 click. Now ur 1& 2 should read closed ( showing ohms or resistance) now place meter prongs on 1 & 4 and you it should now show open ( or no resistance - no ohms) this is how u know ur timer is good, Remember when testing for ohms ADJUST meter to use a high ohms rating in the thousands as the resistance is very high in OHMS. And adjusting to low ohms rating may give a false reading or not show the proper resistance..
THE COMPRESSOR:If you hear a clicking sound coming from the back of your refrigerator/freezer, then the problem is most likely the compressor, relay and or capacitor is overheating or not getting proper power and will not start.The compressor is the component on your refrigerator that allows your refrigerator to cool. If this component is not working properly your refrigerator will stop cooling. Most of the time the compressor is not the component that has failed.
To check ur compressor with multi meter:
Disconnect and remove the relay and capacitor from compressor, some located next to compressor in a casing.
You wills see 3 prongs coming out of compressor. 1 goes to ur start winding, 1 goes to ur run winding and the center goes to ur ground.
Place ur meter connector or prong on the start prong and the other on the ground (center prong) take note of the reading in OHMS for example 5 ohms.
Next place meter prong on run prong and the center ground prong agin. Take note of the reading in OHMS. Example 4 ohms
Next place meter prong on the start prong and the other on the run prong, now take note of the reading example 9 ohms. Now match the total of this ohms test with the total of ur two separate test. 9 ohms, if they match ur ok give or take 5 percent plus or minus. One more test to make to test of there is a short in compressor attach meter prong to ground prong and rub the other end of meter prong to metal ( scrape the metal clean of paint and test on metal surface not painted surface. If it shows continuity or ohms , u have a short in ur compressor. It should show infinity
TO REPLACE RELAY AND CAPACITOR WITH A HARDSTART KIT YOU CAN USE
A 3 in 1 start kit for compressors sizes 1/4 through 1/3 HP. And a 5 in 1 for higher H.P. (BE SURE TO MATCH WITH UR COMPRESSOR MODEL NUMBER AND TYPE) The kit includes relay, capacitor, and overload device, pre-wired. The kit will replace all 3 electrical components on capillary refrigeration systems. For newer systems with a run capacitor use proper kit. For smaller horsepower compressors useTJ90RCO810.
The wire set up is as follows the red wire goes to the right side of compressor prong, the white wire to the left side prong, the black wire to the center prong, and the 2 other black wires go to the power and the ground connection
Lastly you should also check ur THERMISTORS in the freezer and fridge section for continuity OHMS and for amount of OHMS current being put out. In most models around 13000 ( give or take 150 ohms) ohms is required.
1-3 TEMPERATURE CONTROL
As the food in the fridge gets colder, it gives off less heat, and the air inside the fridge will remain colder. A thermostat called aCOLD CONTROLwill cycle the cooling system on and off to keep the temperature inside your fridge within a certain range. You can adjust that range using one of the dials within your fridge.
On most fridges, all the cold air for both the food compartment and the freezer compartment is produced in one evaporator. Since the freezer is so much colder than the food compartment, most of the cold air that is produced circulates to the freezer compartment. Only a small amount is needed in the food compartment to keep it down to the proper temperature. This amount is adjusted by a smallAIR DOORin the duct between the evaporator and the food compartment. The control for this air door is the other of the two dials within your fridge.
If you hear your compressor "short-cycling" (starting and stopping at short intervals) try jumping across the two leads of the cold control thermostat ( in the fridge compartment) with an alligator jumper. You can also check both for live voltage current and ohms- If there is a greenthirdlead, ignore it for this test; it is the ground wire. If the fridge starts running constantly, the cold control is bad. Replace it.
To test or change the cold control, first Pull the knob off it and remove any plastic cover plate or housing from it.
You will see two wires leading to it. There will also be a thick, stiffCAPILLARY TUBEattached. The capillary tube is the liquid-filled temperature-sensing element of the cold control, and operates in the same manner as a thermometer

Refrigerator Is Not Cooling What To Check And How To FixRefrigeration System Basics Chapter 1Troubleshooting Thermistor Problems in RefrigeratorsTop Freezer Thermistor Testing Replacement
here are lots of things that can cause cooling problems. One of the most common causes of poor cooling in a frost free refrigerator is a defrost system failure. In such a case one or the other compartment may appear to be keeping proper temperature but that too may change in a short period of time. The fridge compartment's temperature rise is usually (but not always) the first to be noticed. Frost" and "Ice"
There is a difference between "frost" (a white, snow-like substance) and "ice" (usually clear and solid). When referring to what is seen during an inspection, please keep this distinction in mind as the possible causes for each are often very different. The Defrost System
Inspecting the (usually rear) wall of the freezer compartment for a frost build up is necessary. (In the case of many GE top freezer models, check the freezer's bottom panel.) If there is a frost coating on it, it is often a sign of excessive frosting beneath it. Sometimes however the evaporator cover panel will actually need to be removed (see the illustration below) before an excessive frost build will visible.
The refrigeration system's evaporator (cooling) coil is usually in the freezer compartment. This evaporator will periodically frost over and have to be defrosted by means of a heating system. When the defrost heating system fails, the frost can accumulate to such a degree that airflow throughout the appliance is hampered. There may be just enough air circulation to cool the freezer section but that will eventually stop too.
Unplug it - but I don't recommend that.
The flashing light indicates that it is working - and you can see it from a distance. Saves walking down the stairs to open the door of the freezer in the basement.
Worry about your freezer if the light goes OUT.
Good Luck

Thanks.
the refrigerator is what cools the water so if that working than the water should be somewhat cold unless you dispense a lot of it. Otherwise its a bad design by the manufacturer.
takes time for the temperature inside the fridge -freezer to normalize after doors are being left open
turning off a fridge freezer on and off wont help it
it takes time to for the thermostat to kick start the compressor
and more time to reach the freezing temp lost
if you are certain the thermostat is damaged
call in a service man
have the thermostat replaced and have them check
the gas in the system is running the correct pressure
Good day, please check at the back, at the bottom where the compressor is located for the pencil dryer(as in photo). Get a nice firm grip on it just be careful and feel the temp if it's cold or one side is hot and the other side cold the dryer is block. Otherwise feel the thickest pipe running into the compressor it should be cold if the fridge has been running for a while and the thin copper pipe existing the compressor should be hot. If the thin pipe is freezing up with a thick layer of ice and the dryer as some med-temp then there's a gas leak. If the thin copper pipe is very hot and the dryer has no temp then there's a blockage but if the thin copper pipe feels med-temp and the thick copper pipe more or less the same but a bit cooler the compressor is not pumping also feel if the compressor is running. If dryer as a warmth temp and the thin copper pipe is hot and the thick one very cold(when tipping your finger on your tongue and pressing it against the pipe your finger should stick a bit) if all checks out then it's the thermostat switching the compressor off at the rong temp.
Check the harness connection at the hinge on the left door disconnect then reconnect. Also check temperature in freezer make sure it's at or close to 0deg f
If you mean the refrigerant, I would not recommend it. If the refrigerant has leaked out, there is a leak. The system is contaminated with moisture, and the leak needs to be repaired, filter drier replaced, a vacuum pulled on the system, and a proper charge amount put back in.
The freezer is the important side- if the unit can maintain fridge temps, but not freezer temps- you have a sealed system leak and are losing the refrigerant volume needed to create sufficient cooling. When you remove the freezer panel, there should be a fine layer of white frost across the entire length of evaporator tubing... GE Compressor WR87X20798
Whats happen is the machine has gone into stand by because the doors was left open to sort it out what you need to do is
turn the freezer knob to off then turn it back on again this should restore it.
