My Refrigerator and Freezer Are Not Cooling. What's the matter?
If your refrigerator and freezer are not cooling, try the following:
Make sure the appliance is plugged in properly. If it is not, remove the plug from the socket and then re-insert it. If the plug is properly inserted, remove the plug and try plugging another item into the same socket. If the newly plugged in item does not work, try resetting the circuit breaker for that outlet.
Lower the temperature control settings in your refrigerator and freezer. Let the refrigerator run for several hours and then re-check the temperature.
If your refrigerator is in direct sunlight or located near a heat source, move the refrigerator if you can. If you cannot move it, lower the temperature controls in your refrigerator and freezer.
Move the refrigerator so that its back is farther from the wall. The minimum clearance required between the back of the refrigerator and the wall is one inch.
Make sure that both the freezer and refrigerator are 1/2 to 3/4 full. The refrigerator will not cool properly when empty.
Make sure that the condenser coils are not covered with dust. You can clean the coils easily with a rag or vacuum cleaner with a brush attachment.
Unplug the refrigerator for 1 minute, then plug it back in. If your refrigerator is in demonstration mode, unplugging it, then plugging it back in resets the refrigerator to regular mode.
If none of these actions resolve your cooling problem, call Samsung Customer Service.
