What to do when you see frost buildup in the freezer of your Haier 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.
