DA47-00243K Defrost Thermostat – Stop Frost Buildup Before It Kills Your Samsung Refrigerator's Cooling
When the defrost thermostat fails, your Samsung refrigerator's evaporator coils ice over completely — blocking airflow and causing the entire cooling system to fail. The DA47-00243K is the genuine OEM thermostat that monitors evaporator temperature and signals the defrost heater to cycle on and off at the correct thresholds. Without it working properly, frost accumulates unchecked, fans strain against ice blockages, and what starts as a minor defrost issue becomes a full compressor-load problem.
✓ Symptoms That Point to This Part
- Excessive frost or solid ice buildup on the back wall of the freezer
- Freezer section too cold — fresh food compartment freezing over
- Refrigerator running constantly but not cooling properly
- Ice buildup on evaporator coils (visible after removing freezer back panel)
- Water pooling or leaking inside the refrigerator cabinet
- Fan making loud noise or humming against ice obstruction
- Defrost cycle not running — confirmed with defrost test mode
✓ Part Details
- OEM Part Number: DA47-00243K
- Manufacturer: Samsung (Genuine OEM)
- Component: Defrost Thermostat / Thermal Limiter
- Function: Monitors evaporator coil temperature; opens circuit to cut heater power at upper threshold, closes to allow defrost cycle at lower threshold
- Fit Type: Direct OEM replacement — no modification required
💡 Pro Tip — Check the Defrost Heater & Sensor While You're In There:
If you're already pulling the freezer back panel to replace the thermostat, inspect the defrost heater (DA47-00244C or equivalent) and the defrost sensor at the same time. These three components work as a system — a failed thermostat often means the heater has been running uncontrolled or not at all, which stresses the sensor. Replacing all three during the same labour visit prevents a callback and saves your customer a second service call.

✓ Installation Notes
- Skill Level: Moderate DIY — comfortable with panel removal and connector work
- First Step: Disconnect power to the refrigerator before beginning any disassembly
- Access: Remove freezer contents and back interior panel to reach evaporator coils
- Defrost First: If coils are heavily iced, manually defrost (hair dryer or 24-hour unplug) before attempting removal
- Connector: Note orientation of the thermostat connector before disconnecting — reinstall in same position
- Test: Run a forced defrost cycle after installation to confirm proper operation before closing up
