dEWarning
LG Refrigerator dE Error Code
The damper door that controls cold air flow from freezer to refrigerator is not functioning. This can cause temperature issues.
Common causes
- Damper motor failure
- Ice buildup blocking damper movement
- Wiring or connector fault
- Control board issue
How to fix it
- Unplug refrigerator and locate the damper (usually in the back of the fridge compartment).
- Check if damper door moves freely; if stuck, use a hair dryer to melt ice.
- Listen for a click when power is applied; if no movement, test motor resistance (usually 100-200 ohms).
- If motor tests bad, replace it.
⚠ When to call a pro: Call a technician if damper moves freely but code persists, as the board may need replacement.
