Question about Refrigerators
Hi Angela,depending on the style of refrigerator you have it could be a couple of different things. Most common problem would be the self defrost system. Probably the defrost thermostat or the defrost heater. Second would be the defrost timer,which would keep it from going into defrost. That would be either a mechanical timer or a computer board. It could also be a failed airflow diverter,which opens and closes to allow cold air to flow into the fresh food section from the freezer. Check the back wall of the freezer,if it's covered with frost then that is definitely a no defrost symptom. Hope that helps.

The fridge gets its cold air from the freezer through a vent
between the freezer and fridge.The fan in the freezer blows air through
it. There is a flap you adjust with the
fridge temp. control. Make sure it's opening and closing when you adjust the
If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

HI, you will need to inspect the compressor to make sure it is cycling in intervals. if the compressor is not cycling, this will confirm compressor failure. The evaporator fan blows cold air into the freezer and from there it vents into the refrigerator. Occasionally the vents between the freezer and refrigerator can become clogged with ice, food or other debris. In most refrigerators the cold control for the refrigerator opens and closes these vents. That mechanism may become inoperative resulting in the vents becoming stuck open or closed.
Inspect the vents to determine what is preventing the free flow of air. An overcrowded refrigerator or freezer may be the cause. In other cases the vents may need to be cleaned or ice melted away. To remove a build up of ice, use a hair dryer set to "low". Using a higher setting may damage the freezer. CAUTION: Do not let melting ice drip onto the hair dryer. In some models, the vent is located under the temperature control console. The housing either snaps into place or is held in place with screws. Remove the screws, or gently depress the retaining clips with a small screwdriver. Allow the housing to hang by its wiring. A freezer vent control may also have to be removed to access the vent. In some freezer-on-top models, it may be necessary to remove the floor of the freezer to inspect for obstructions.
The condenser coils dissipate heat. If dust and debris accumulate around the coils, your refrigerator may not be able to cool properly, it may run continuously or it may stop completely as a result of an overheated compressor. You should clean rear-mounted coils once a year. Unplug the refrigerator before cleaning. Refrigerators are heavy, never tip one forward or backward. Never attempt to move a refrigerator without an assistant. Vacuum or brush the coils. If coils have a filmy build-up, use warm soapy water to clean them. Take care not to spill or drip water onto the components of the refrigerator.You should clean floor level coils at least twice a year. Unplug the refrigerator before cleaning. Vacuum or brush the coils. Remove the grill from the front of the refrigerator and use a vacuum with a wand attachment to remove any dust and debris. The grill should snap off and on. Pull firmly toward you and possibly upward to remove the grill. If it does not come off with a modest effort, check for screws or retaining clips that may hold it in place.
Another inspection point will be the door seals. This is a easy way for the cold air to escape from your unit as well. thsi will cause the temperature to rise. The seal should make smooth continuous contact with the refrigerator case. When the seal does not seal completely, warm air enters the appliance. This results in more frequently compressor operation and possibly the inability of the appliance to maintain proper temperature. To test the seal, use the dollar bill test. Place a a dollar bill or a piece of paper between the seal and the refrigerator and close the door. Now pull the paper out. You should feel tension as you pull. Retest along the entire door seal. Replace the seal if the test was unsuccessful.
Next will be the door switch. The interior light in most refrigerators, and the fan in some, is controlled by a door switch. When the door is closed, the switch is depressed and the interior light goes off and the fan resumes normal operation. If the door is misaligned or the switch malfunctions, the refrigerator may become warm as a result of the non-operation of the evaporator fan and the heat generated by the interior light. Test the switch for continuity using a multimeter. Set the multimeter to the ohms setting X1. Place a probe on each terminal. The multimeter should change from a reading of infinity to zero when the probes touch the terminals. With the probes still touching the terminals depress the switch, the reading should change back to infinity. If it does not pass both of these tests, the switch should be replaced.
Be sure to confirm evaporator fan function as well. if the fan is defective, it will prevent proper cooling as well.
This will conclude the most common issue with a under preforming unit. I would advise to check all the above and, if the unit continues to not cool after all the above adjustments are made, i will recommend replacing the cold control device and thermostat.

To solve this problem, you must open the compressor area at the back bottom of the refrigerator and chek the temperature of the pressure line. If the temperature is between 55celcius to 60 than its ok. Or else you need to change the refrigerant.
I suggest you to contact the service authority.
Thanks for contacting Fixya.

If there is no cooling on the fridge but the freezer is cooling then the compressor and gas pressure seems good. So to check the set for blocks in the ducts we must shut off the fridge.Keep it 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 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.
The fan making noise can be due to frost build up .If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
Do not set thermostat up to max but keep it to normal .So try this test from the outside and make your observations so that we come to the solution.
