What to do when you see frost buildup in the freezer of your Kenmore Elite bottom-mount refrigerator

When frost is building up in the freezer, check first for a break in the door gasket or drawer gasket that could be letting in warm, moist air. If the gasket seems sound, a malfunction somewhere in the automatic defrost system could be the culprit.

A failed defrost timer or a bad electronic control board may not initiate the automatic defrost cycle, causing excessive frost buildup on the back wall inside the freezer. A faulty defrost sensor can prevent the defrost heater from turning on the defrost cycle.

Maintenance tips for your Kenmore Elite bottom-mount refrigerator

Routine maintenance helps your refrigerator run more smoothly, so it uses less energy. Clean the condenser coils regularly to help the sealed system cool down the refrigerator efficiently. The compressor won't run as frequently if you keep those condenser coils clean.

Adjust the refrigerator door(s) to prevent air leaks into the refrigerator and freezer compartments. Air leaks cause frost buildup on the evaporator, which interrupts airflow and causes cooling problems.

Routine maintenance can also help prevent odor problems. Change the air filter regularly if your model has an air filter. Clean the inside of the refrigerator so spills don't build up and cause smells. Clean the drain pan under the refrigerator regularly because that pan can attract bugs or residue that causes odors.
