Troubleshooting

Refrigerator does not cool properly

Cause: Vents are blocked, door left open, or thermostat set incorrectly

Solution: Check that air vents are not blocked by food or plastic bags, close door completely, verify temperature settings are correct

Water dispenser not working

Cause: Water filter clogged, water line not connected, or water supply line shut off

Solution: Replace water filter, check water line connections are tight, verify main water supply is on

Ice maker not producing ice

Cause: Water line disconnected, water filter clogged, or ice maker turned off

Solution: Press Test button on ice maker to verify operation, check water line connection, replace water filter if needed, verify ice maker is turned on

Door will not close properly

Solution: Use leveling feet to properly level refrigerator, check door alignment and adjust using snap rings if needed

Abnormal sounds from refrigerator

Cause: Normal operational sounds or ice making in progress

Solution: Allow 1-2 days for ice maker to normalize, listen for specific sound type in troubleshooting section

May require a professional

Cause: Door left open frequently or large amount of food added, causing temperature to rise above set point

Solution: Close door completely, reduce amount of food added at once, allow time for temperature to stabilize

Water from dispenser has abnormal smell or taste

Cause: Water dispenser not used for 2-3 days

Solution: Discard first 1-2 glasses of water before using

Water appears cloudy when dispensed

Cause: Water pressure increase during filtering causes oxygen and nitrogen saturation

Solution: This is normal; water will clear after a few seconds

Cause: Water line not properly connected or pitcher not seated correctly in holder

Solution: Check water line connection, remove and reseat pitcher in holder, check for moisture on pitcher contact points

Ice bucket tray not staying in place or ice dropping behind bucket

Cause: Ice bucket not fully inserted

Solution: Ensure ice bucket tray is fully inserted until it clicks into place

Ice chunks forming in bucket

Cause: Ice stored for long time undergoes sublimation, or clumping after power loss

Solution: Empty ice bucket and remove clumped ice, turn off ice maker if extended storage expected, discard first buckets after power failure

Door bins falling or not staying in place

Cause: Bin not inserted fully or filled with too much weight

Solution: Empty bin, insert slightly above final position ensuring back is against door, press down firmly
