How to Fix Samsung Refrigerator Error 2

Error Code: Refrigerator Difficulty: Moderate

Problem: Flash code 2: Refrigerator temperature sensor fault (non-display models); identical failure mode to 2E code

How to Fix Refrigerator Error

1. Unplug refrigerator from electrical power source.
2. Remove fresh food compartment shelves and interior panels to access temperature sensor mounted on rear wall or evaporator cover.
3. Disconnect wiring harness connector from sensor assembly.
4. Measure resistance across sensor terminals with multimeter at current refrigerator temperature. Expected value: approximately 10kΩat 37°F/3°C (±10%).
5. If reading is infinite, near zero, or significantly deviates from specification: remove mounting hardware securing sensor.
6. Carefully extract old sensor from mounting location. Clean mounting area thoroughly with isopropyl alcohol.
7. Apply thermal conductive paste to sensing tip of new sensor.
8. Install replacement temperature sensor using OEM part DA32-10105R. Ensure proper seating in mounting well.
9. Secure mounting clip or screw to 3 in-lbs torque. Route wiring harness away from evaporator coils and sharp edges.
10. Reconnect harness firmly. Reassemble interior components. Restore power and verify refrigerator temperature stabilizes at set point within 4 hours.

Still Not Working?

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
