The Kenmore refrigerator includes an automatic defrost timer that cycles on and off when the refrigerator prepares itself for routine maintenance, and it clicks during the cleaning cycle. The refrigerator's motor may make a loud clicking noise when the defrost timer's motor requires replacement, and it can be replaced by a Sears professional technician to eliminate the noise.
The thermostat control pushes air through the refrigerator to maintain cool temperatures in the refrigerator and freezer section, and that process causes a continuous ticking noise. This noise comes from the appliance's compressor motor, which makes the ticking sound until the compressor shuts off after the appliance reaches the specific temperature.
The appliance typically hums during operation, but it can create a ticking noise when the refrigerator's legs are not level with each other. The refrigerator's legs can be adjusted with a wrench to raise or lower the leg on the bottom of the refrigerator.
The refrigerator door's hinges may be loose, resulting in an alignment problem that causes ticking while the refrigerator's fans are running. A rotating lever is located near the bottom of the refrigerator, and it can be turned clockwise or counterclockwise to make the doors level with the appliance.
