Safe external checks

Clear exterior airflow or clean the accessible filter, then use the documented reset.

  1. Clear exterior obstructions and open an existing ventilation window or screen around the outdoor unit.
  2. In heating mode, clean the accessible indoor-unit filter according to the exact model instructions.
  3. Disconnect power for five minutes and restore it after the supported exterior check.

Safe checks and when to request service

Repeated CH61 requires LG inspection.

  • Request LG service if CH61 repeats.

Separate hazard signs such as smoke, flooding, sparks, or a burning smell require the manufacturer's safety instructions.

Do not do

Do not move installed units, build or alter air guides, open panels, or work on electrical, fan, compressor, or refrigerant components.

Limit work to accessible filters and unobstructed exterior ventilation; do not move installed equipment or touch the heat exchanger.

Check warranty before authorizing service

Warranty coverage depends on the country, model, purchase date, and manufacturer terms. Have the model and serial number available, open the manufacturer's official support or warranty page, and ask whether the service route is authorized before paying for work.

This public record does not make a coverage determination. Use the official model lookup and warranty information linked below.
