Ensure the Kelvinator refrigerator is properly connected to a working, grounded power supply if the refrigerator does not turn on or run. Check and replace the local fuse or reset the circuit breaker if necessary.
Close the refrigerator door and leave it shut for several hours if the refrigerator is running excessively. Warm temperatures caused by frequent opening of the door or placing large amounts of warm food inside the compartment will cause the motor to run longer to cool the unit down.
Turn the temperature control knob to a warmer setting if the food inside the refrigerator is too cold or turn it to a cooler setting if the food inside the refrigerator is too warm. Wait several hours for the new temperature to adjust.
Place plywood or metal shims underneath the refrigerator to level out the surface if the refrigerator is rattling or vibrating excessively, which indicates the floor is not level.
Cover food tightly and discard expired food if odor develops in the refrigerator. Wipe down the interior with a warm, damp sponge and baking soda to remove the odor.
