Adjust the thermostat to a suitable position. The target temperature may be too low for the refrigerator to realistically achieve.
The fresh food compartment should be set to 40 degrees Fahrenheit to slow bacterial growth and prolong the life of items such as milk and yogurt. The freezer, if fitted, should be set to 0 degrees Fahrenheit.
Make changes using the arrow buttons on the control panel or by turning the thermostat dial to a higher number.
Watch what happens when the weather changes. Hot and humid conditions cause the compressor to work harder to maintain the target temperature.
You might find the compressor runs non-stop during periods of extreme heat. Consider moving the appliance to a cooler location in your home if the problem persists.
Change the way you use the refrigerator. Leaving the door open for long periods, adding large amounts of hot food or leaving the refrigerator empty may cause the compressor to run more frequently.
Avoid blocking any air vents at the back of the refrigerator with food. Misplaced shelves or items could be holding the door open.
Make sure the rubber door seals touch the refrigerator when the door is closed.
Re-examine the refrigerator's installation; there may be insufficient air circulation clearance to maintain a consistent temperature or a source of heat near the appliance. Make sure there is a minimum of 5 inches clearance at the top and back and an inch on the sides.
Avoid placing the refrigerator near ovens, heaters, radiators or dryers.
De-ice the refrigerator if it is not a frost-free model. More than 1/2 inch of ice on the rear or side walls will contribute to increased running time.
Move food to a safe location, unplug the refrigerator, open the door and wait for the ice to melt. You will need to place towels around the appliance to catch any spills.
