It doesn't get a cold in the refrigerator section

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,thermostat and main circuit board.

Concerning the order issue

The door seals form an airtight seal in the refrigerator.Mildew can form on the door seals, which can cause an unpleasant odor and can cause the seals to become brittle and crack. Periodically clean the door seals with a toothbrush and a solution of warm water and baking soda or water and bleach. Gently pull the seal to expose the folds. Be careful not to pull too hard or you might tear the seal. This will prevent the seal from forming correctly, when the unit door is closed.

If they are torn or warped, they cannot form a tight seal with the refrigerator and should be replaced.

Ok, The next order causing area will be the Breaker Strips.

The breaker strips are located just inside the front of the refrigerator case, near where the door seal makes contact. If the breaker strips are warped or cracked, they may allow moisture to get into the insulation between the inner and outer walls of the refrigerator. This will cause internal mildew, and mold to form, in return producing a foul order. To remove the breaker strips it is important to bring them up to room temperature first. If they are too cold they will be brittle and may crack. To warm the strips you can open the freezer and allow it to come up to room temperature (wait 2 to 4 hours) or you can soak a towel in warm water and hold it against the strips to warm them. Determine whether anything must be removed (such as the control console, or damper), before the breaker strips can be removed. Attempt to remove the strip by pulling it away from the refrigerator case(GENTLY). If that does not work, softly, slide a putty(Or equivalent) knife under the strip. Instead of prying the strip, slide the knife along the seam, rocking it where necessary to separate the strip. Some breaker strips are held in place with a sealant, which will have to be cut with a utility blade.

If the insulation is damp or has an unpleasant odor(Once exposed), leave the strip off to allow the insulation to dry. (I do Not recommend using any alternative drying method. Air dry is the best action). You can Replace the breaker strip, by using a food grade sealant if necessary.
