Frequently Asked Questions (FAQ)
- Q. Can I Continue Using My Refrigerator While an Error Code Is Displayed?
-
A. Some features may
continue to work, but your refrigerator may not be able to control
its internal systems correctly.
If the error code persists, minimize use and contact LG Customer Support for assistance.
- Q. The Error Code Disappeared After I Reset My Refrigerator. Can I Continue Using It?
-
A. Yes, the error may
have been caused by a temporary power or communication issue.
However, if the same error code returns, stop using your refrigerator and contact LG Customer Support, as this may indicate a faulty internal circuit or wire.
- Q. Can I Continue Using My Refrigerator If an Er dH, Er d1, Er d2, Er d, Er H1, or Er H2 Error Code Appears?
-
A. Your refrigerator may
operate normally once the ice on the cooling plate is removed, but
the error may return over time.
To temporarily resolve the issue, remove all food from your refrigerator and place dry towels on the floor in front of the doors.
Then, unplug the power cord from the wall outlet and leave the doors open for at least 12 hours.
However, frequent errors can decrease cooling performance and affect food quality, so we recommend contacting LG Customer Support for assistance.
