If the defrost drain is frozen, the water will overflow the drain trough and drip down to the bottom of the compartment. This water can eventually leak onto the floor. Check the defrost drain to determine if it is clogged or frozen. If the defrost drain is frozen, thaw the ice. In addition, flush the drain with hot water to ensure that it is clear of debris.
Self-defrosting refrigerators are equipped with a drain pan. The drain pan collects the water that melts from the evaporator coils. In order to evaporate the water in the drain pan, the condenser fan blows warm air from the condenser coils across the top of the drain pan. Because the condenser fan evaporates the water from the drain pan, the drain pan does not have to be emptied. However, if the drain pan is cracked, it will leak water as the defrost cycle is running. Inspect the drain pan for cracks. If the drain pan is cracked, replace it.
