The refrigerator that was replaced was an older model. The room temperature is warmer than normal. Compressor seems to run too much. The door is opened often or a large amount of food has just been added. The refrigerator was recently plugged in and the refrigerator control was set correctly. The refrigerator control is not set correctly for the surrounding conditions. Solutions Firmly plug the cord into a live outlet with proper voltage (see Electrical & Grounding Requirements). Replace the fuse or reset the circuit breaker. If the problem persists, contact an electrician. Refer to the Setting the Controls section. Wait about 30 minutes for defrost cycle to end.

NOTE: The refrigerator and freezer compartment lamps are LED interior lighting, and service should only be performed by a qualified technician. Floor is weak or uneven or leveling legs need adjusting. See the Installation section for leveling instructions. Modern refrigerators require more operating time but use less energy due to more efficient technology. The compressor will run longer under warm conditions. At normal room temperatures (70°F) expect your compressor to run about 40% to 80% of the time. Under warmer conditions, expect it to run even more often. The refrigerator should not be operated in surrounding temperatures above 110°F. Adding food and opening the door warms the refrigerator, requiring the compressor to run longer in order to cool the refrigerator back down. In order to conserve energy, try to get everything you need out of the refrigerator at once, keep food organized so it is easy to find, and close the door as soon as the food is removed. (Refer to the Food Storage Guide.) The refrigerator will take up to 24 hours to cool completely See the Adjusting Control Settings section. The doors are not closed completely. The back cover is dirty. Firmly push the doors shut. If they will not shut all the way, see "Doors will not close completely" in the Troubleshooting section. This prevents air transfer and makes the motor work harder. Clean the back cover. Refer to the Care and Cleaning section. 23
