Samsung Refrigerator Troubleshooting
| PROBLEM | SOLUTION |
|---|---|
| The refrigerator does not work at all or it does not chill sufficiently. | • Check if the power plug is properly connected. • Check if the set temperature on the digital display is warmer than the freezer or fridge inner temperature. If it is, set the freezer or fridge to a colder temperature. • Is the refrigerator in direct sunlight or located near a heat source? If so, it may not be able to cool sufficiently. Install it in a location that is out of direct sunlight and not near a heat source. • Is the back of the refrigerator too close to the wall, preventing proper ventilation? If so, it may not be able to cool sufficiently. Keep it an appropriate distance from the wall. • Is there too much food inside so that the food is blocking the outlet vent? To keep the refrigerator at a suitable temperature, do not fill the refrigerator with too much food. |
| The food in the fridge is frozen. | • Check if the set temperature on the digital display is too low. If so, raise the set temperature inside the refrigerator. • Is the temperature in the room too low? Set the refrigerator warmer. • Did you store food with a high moisture content in the coldest part of the refrigerator or near the cooling outlet vent? Try moving those items to the other shelves in the fridge instead of keeping them in the colder areas or bins. |
| You hear unusual noise or sounds. | • Check if the refrigerator is level and stable. • Is the back of the refrigerator too close to the wall, preventing proper ventilation? • Was anything dropped behind or under the refrigerator? • If you hear a “ticking” sound from inside the refrigerator, this is normal. It occurs because various parts contract or expand in response to temperature changes in the refrigerator interior. • If it sounds as if something is hitting something else inside the refrigerator, this is normal. The sound is caused by the compressor operating at high capacity. |
| The cabinet-door sealing area of the appliance is hot and condensation is occurring. | • Some heat is normal as anti-condensators are installed in the vertical hinged section of the refrigerator to prevent condensation. • Is the refrigerator door ajar? Condensation can occur when you leave the door open for a long time. |
| The ice Maker is not producing ice. | • It may take longer to make ice if it is not sufficiently cool, such as when first installed. • Is the water line connected and the shut-off valve opened? • Did you manually stop the ice making function? • Check if the filter is properly installed. If it is not properly installed, the ice making function may not work. |
| You can hear water bubbling in the refrigerator. | • This is normal. The bubbling comes from refrigerant circulating through the refrigerator |
| There is a bad smell in the refrigerator. | • Check for spoiled food. • Foods with strong odors (for example, fish) should be tightly covered. • Clean out the freezer periodically and throw away any spoiled food. When cleaning the inside of the fridge, store food elsewhere and unplug the appliance. Wipe with a dry dishcloth after 2-3 hours and then circulate air inside the refrigerator. |
| Frost forms on the walls of the freezer. | • Is the air vent blocked? Remove any obstructions so air can circulate freely. • Allow sufficient space between the stored foods for efficient air circulation. • Is the freezer drawer closed properly? If the freezer drawer is not completely closed or is blocked, humidity from outside may enter and cause severe frost to form |
| The water dispenser is not functioning. | • Is the water line connected and the shut-off valve opened? • Has the water supply line tubing been crushed or kinked? • Make sure the tubing is free and clear of any obstruction. • Is the water tank frozen because the fridge temperature is too low? Try selecting a warmer setting on the Digital display. • Is the Child Lock on? • Check if the filter is properly installed. If it is not properly installed, the water dispenser may not work. |
| The auto close system does not work with the freezer door. | • Is there an imbalance between the right and left parts of the door? • Open and close the door smoothly 1~2 times. After you do this, the auto close system usually works properly again. • Try opening the door smoothly to avoid unbalancing the right and the left part of the door. |
| Condensation or water drops forms on vertical mullion and surroundings, etc. | • Condensation or water drops may form if the humidity is too high while the refrigerator is operating. • If condensation or water drops appears on vertical mullion and surroundings, etc., turn the Energy Saver mode off after removing the condensation. |
