RF4287HARS Unusual Noises from the Back of the Refrigerator
If the refrigerator is making an unusual noise, verify/perform the following:
Warning: If a water line is not connected, do not press down on the dispenser lever, as this will eventually ruin the water valve and prevent use of the water dispenser and ice maker in the future.
- Move the refrigerator forward approximately 2 inches. If the noise goes away, that indicates the refrigerator was coming in contact with another object, such as the water line or a wall.
- Verify the water line is connected and that water is being supplied to the fridge. If the water line is not connected or water is not supplied the fridge, the water valve in the back of fridge will make a buzzing or ratcheting sound. Turn off the ice maker to keep this sound from occurring.
- Verify that the water pressure is not too high (see the section below).
Checking the Water Pressure:
Important: When checking water pressure, the amount dispensed in 10 seconds must be at least 6 ounces (¾ cup). Less than that amount indicates water pressure is too low for the dispenser and ice maker to function correctly. Increase the water pressure until at least 6 ounces is dispensed in 10 seconds.
High water pressure can cause rattling, grinding, or other loud noises from the back of the refrigerator, particularly when dispensing water.
If the noise continues, perform the following:
- Check the water pressure by dispensing water into a measuring cup for 10 seconds.
- If at least 6 ounces dispenses, but the noise continues, turn down the water valve slightly to decrease the pressure.
- Repeat the above steps until the noise stops or less than 6 ounces dispenses in 10 seconds.
Note: There is no maximum or recommended value for the water pressure other than exceeding the minimum requirement. As long as the noise stops and the minimum requirement is met, water pressure may be set as desired.
If the noise continues after performing the steps above, service is required.
