LG refrigerators dH error

The refrigerator did not reach the expected evaporator temperature during defrost within one hour.

dH

What this code can mean

LG identifies dH as a defrost-cycle error and documents a two-minute power reset before service is requested for a persistent code.

Safe first checks

  1. 1
    Protect perishable food before interrupting refrigerator power.
  2. 2
    If the power connection is dry and undamaged, unplug the refrigerator for two minutes and then restore power.
  3. 3
    Allow the refrigerator to attempt its normal defrost process again.

Possible causes

  • The defrost cycle did not reach its expected temperature in time.
  • A defrost-system component may require service.
Stop conditions
  • Do not remove internal panels or attempt to repair defrost components.
  • Request service if dH returns after the documented reset.

Use LG support or an authorized servicer if the defrost error persists.
