Samsung Refrigerator: clogged drain line
What is this symptom?
If you're experiencing water pooling inside your Samsung refrigerator or freezer, especially under drawers, you may have a clogged drain line. This issue often arises during defrost cycles when melted water can't flow through the drain. Common causes include ice buildup, food debris, or a malfunctioning evaporator fan. Address this problem promptly to prevent further damage and maintain optimal performance.
Important Tips for Samsung Models
- Official Samsung support notes that a clogged or frozen drain hole requires service inspection and cannot be self-repaired per their documentation.

How to Identify: No airflow in freezer, ice buildup even with minimal use, fan blade does not turn freely
Part: Evaporator fan motor
Missing or faulty drain strap or drain heater causing ice blockage
How to Identify: Repeated freeze blockages despite clearing, lack of heat conduction into drain area
Part: Drain strap / drain heater assembly
