Question about Refrigerators
Our Samsung silver nano refrigerator was fine for six years, now it started giving problem, the fan and compressor was working but there was no ice formation or cooling so we called in a refrigerator mechanic and he cleaned the tubes and changed the oil and filled in gas, it worked for two days and again there is no ice formation and no cooling. please help me to proceed.
If everything is fine, check whether the door is closed properly. There may be some vent while closing the door.

There are 2 possible problems. One is the defrost cycle is not working properly this is usually indicated by a large amount of frost on the back freezer panel. If so, the circuit will have to be repaired and the evaperator thawed to remove the ice build up. The other is the fresh food damper is not working properly this is behind the "lump" in the back of the fridge compartment above the top shelf, remove the louver panel to see if it is open or closed. closed will be warm open should be cold. The water dispenser reservoir is probably frozen due to poor air circulation.

If you are sure the fan in the freezer is running and you don't feel any air flow out of the top middle vent inside the fridge section, then the damper motor must be bad. The damper motor is behind that vent cover inside the fridge section.

The compressor is locked up. Basically it is stuck. You can pick up at the local appliance parts store a hard start relay, Home Depot ,Lowes, or or those guys wont have it. Its not too expensive and is worth trying because your only other option is you need to replace the compressor. The part is called a kick start or hard start, the guy at the parts store will know what you are talking about. It is simple to connect and has the wiring directions on it. Sometimes this is all it takes. I have been able to get a stuck compressor to go by placing a short 2x4 on it and whack it with a hammer a few times. This is only a temporary fix though, as it will eventually lock up again, but emergency situation this saved the food. If the fridge has a fan back there make sure it works too, it may have been the original cause. Good luck.

Here is your problem:
There are two temperature sensor wires; one should be routed around the vent on the upper left corner of the "ceiling" of the fridge. It will route inside the plastic cover in the back upper corner.
The second one is critical. It originates inside the cover and must pass through the wall of the fridge into the freezer and rest just inside a hole in the rectangle that passes through from one side to the other. If the very tip of this sensor is not well inside the freezer, the system will think the freezer is too warm, never turn off and the lovours inside the plastic housing described above will jam with ice and get stuck. This piece will have to be replaced but will continue to freeze and break until the sensors are placed in the correct locations. Don't ask me how I know all this.

If the refrigerator isn't cool, you need to answer some questions, then see if the compressor is running.
First, answer these questions:
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:
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:
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.
