LG refrigerator error code H1

LG refrigerator error code H1

This error code means that the system fails chill the freezer compartment properly and there is not enough cold. This may be due to:

  1. Iced-up back wall of the freezer
  2. Evaporator fan failure
  3. Low refrigerant charge

Check the back wall of the freezer compartment and see if there is too much frost on it. If there is, defrost your fridge.

Check the evaporator fan. Open the freezer compartment and listen: it must be running.

Make sure the compressor is running.

If no problem is detected so far, call your local service and have your fridge checked: you may need to recharge the refrigerant.
