■

Is the glass not being held under the ice dispenser long 
enough, causing the ice to spill? Hold the container under 
the ice chute for two to three seconds after releasing the 
dispenser lever. Water or ice may continue to dispense during 
this time.

■

Is an ice cube stuck in the chute and holding the trap 
door open? Remove the cube.

■

Is there a water filter installed on the refrigerator? The 
water filtration system may have air in the lines, causing water 
to drip. Additional flushing may help clear air from the lines. 
Normal dispenser use should flush air from the lines within 24 
to 72 hours.

■

Is there a water filter installed on the refrigerator?
The filter may be full or incorrectly installed. Remove the 
water filter cartridge (see the “Water Filtration System” 
section). Operate the dispenser. If the water flow increases 
noticeably, replace the filter.

■

Has the refrigerator been newly installed? Allow 24 hours 
for the refrigerator to cool completely.

■

Has a large amount of water been recently dispensed? 
Allow 24 hours for the water to cool completely. 

■

Has water not been recently dispensed? The first glass of 
water may not be cool. Discard the first glass of water.

The warmth is probably due to normal operation of the 
automatic exterior moisture control. If still concerned, call for 
service.

■

Are the air vents blocked in either compartment? This 
prevents the movement of cold air from the freezer to the 
refrigerator. Remove any objects from in front of the air vents. 
See the “Ensuring Proper Air Circulation” section for the 
location of air vents.

■

Are the door(s) opened often? The refrigerator will warm 
when this occurs. Keep the refrigerator cool by getting all 
items out at one time, keeping food organized, and closing 
the door as soon as possible.

■

Has a large amount of food just been added to the 
refrigerator or freezer? Adding a large amount of food 
warms the refrigerator. It can take several hours for the 
refrigerator to return to the normal temperature.

■

Are the controls set correctly for the surrounding 
conditions? See the “Using the Control(s)” section.

■

Is the refrigerator not cooling? For models with digital 
controls, turn the unit OFF then ON again to reset. See the 
“Using the Control(s)” section. If this does not correct the 
problem, call for service.

■

Are the air vents blocked in the refrigerator? Remove any 
objects from in front of the air vents. See the “Ensuring 
Proper Air Circulation” section for the location of air vents.

■

Are the door(s) opened often? Avoid humidity buildup by 
getting all items out at one time, keeping food organized, and 
closing the door as soon as possible. 

■

Is the room humid? It is normal for moisture to build up 
inside the refrigerator when the room air is humid.

■

Is the food packaged correctly? Check that all food is 
securely wrapped. Wipe off damp food containers before 
placing in the refrigerator.

■

Are the controls set correctly for the surrounding 
conditions? See the “Using the Control(s)” section.

■

Was a self-defrost cycle completed? It is normal for 
droplets to form after the refrigerator self-defrosts.

■

Are food packages blocking the door open? Rearrange 
containers so that they fit more tightly and take up less 
space.

■

Is the ice bin out of position? For models with an interior ice 
bin, push the ice bin in all the way. If the ice bin does not go in 
all the way, it may not be put in straight. Pull it out and try 
again. For models with an ice bin located on the freezer door, 
the bin should sit level. To remove the bin, press the release 
button on the right side of the bin and lift straight up. Replace 
the bin in the door making sure it is properly aligned and 
snapped securely into place. See the “Ice Maker and Storage 
Bin” section.

■

Are the pans, shelves, bins, or baskets out of position?
Put the crisper cover and all pans, shelves, bins, and baskets 
back into their correct positions. See the “Crisper Drawers 
and Covers” section for more information.

■

Are the gaskets sticking? Clean gaskets according to the 
directions in the “Cleaning” section.

■

Does the refrigerator wobble or seem unstable? Level the 
refrigerator. See the “Adjust Doors” and “Level Refrigerator” 
sections in the Installation Instructions.

■

Are the gaskets dirty or sticky? Clean gaskets according to 
the directions in the “Cleaning” section.
