What can you do when you hear unusual noises from the back of your Samsung refrigerator

Gently slide the refrigerator forward by approximately 2 inches (5 cm). If the noise ceases, it may indicate that the appliance was in contact with another object, such as the water line or the wall. This repositioning can often resolve the issue.

Check if the water line is properly connected and the water supply is turned on. A disconnected water line or an inactive water supply can cause the water valve at the back of the fridge to emit a buzzing sound. If the water line is not connected, turn off the ice maker to prevent this noise. Avoid using the water dispenser lever under these circumstances, as it could damage the water valve and ice maker over time.

An effective method to test water pressure is by dispensing water into a cup; approximately 6 ounces (177 ml) should be dispensed within 10 seconds. If more dispenses, the pressure might be too high, potentially causing splashes. Conversely, if less water is dispensed, it suggests low pressure. Ensure the water valve is fully open and consider replacing the water filter. If problems persist, consulting a plumber is advisable.

Adjust the water valve if the pressure is too high. Samsung refrigerators operate efficiently within a water pressure range of 20 to 125 psi (138 to 862 kPa), which provides a wide scope to adjust the pressure to eliminate noise while staying within the recommended range.
