If the refrigerator isn't cold enough, first check whether containers are blocking airflow at the vents; the owner's manual usually shows where the vents are. Your refrigerator also might seem warmer than usual for a day if you’ve just added a lot of food—wait 24 hours after adding lots of food to see if the refrigerator cools properly.
High temperatures are also a sign of a control system problem, a failure in the air control damper, low refrigerant charge, and other malfunctions. Watch the troubleshooting videos below for more tips on resolving refrigerator cooling problems.
These repairs may help solve your refrigerator problem：
The refrigerator defrosts sensor-also known as the defrost bi-metal termination thermostat-trips when it detects that the temperature of the evaporator is getting hot enough that it might overheat. When the defrost sensor trips, it shut off power to the defrost heater. If the defrost sensor trips because it's not working correctly, frost builds up on the evaporator fins, eventually making the refrigerator and freezer not cool well. You can use a volt/ohmmeter to check the defrost sensor for continuity. Replace the defrost sensor if it shows no continuity at around 0 degrees F.
