How to Fix Samsung Refrigerator Error 1

Error Code: Refrigerator Difficulty: Moderate

Problem: Flash code 1: Freezer temperature sensor fault (non-display models); identical failure mode to 1E code

How to Fix Refrigerator Error

1. Unplug refrigerator from electrical power or switch off dedicated circuit breaker.
2. Remove freezer interior panels to access temperature sensor mounted on evaporator cover or freezer wall.
3. Disconnect wiring harness from sensor connector. Note routing path before removal.
4. Measure resistance across sensor terminals with multimeter at current freezer temperature. Compare to service manual chart (e.g., at 0°F/-18°C should be ~17kΩ).
5. If reading is infinite (open circuit), zero (shorted), or deviates >15% from specifications: remove mounting clip or screw securing sensor.
6. Gently extract sensor from mounting well without damaging threads or surrounding components.
7. Clean mounting well thoroughly with isopropyl alcohol and lint-free cloth.
8. Apply thin layer of thermal conductive paste to sensing tip of new sensor.
9. Install replacement temperature sensor using OEM part DA32-10104R. Secure in mounting clip or with screw tightened to 3 in-lbs.
10. Route wiring away from sharp edges and moving parts. Reconnect harness until audible click. Reassemble interior panels. Restore power and monitor freezer temperature for 2 hours to confirm accurate readings.

Still Not Working?

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