Can I fix LG code IF myself?

Start with these safe checks: Request service. LG lists IF among the codes that need a technician. Keep the doors closed meanwhile.

When should I call a technician for code IF?

Keep the doors closed meanwhile. Don't open the sealed refrigerant system, cut or braze lines, or add refrigerant. That needs an EPA-certified technician. Turn power off at the breaker or disconnect before opening any panel, and leave capacitors, compressors and control boards to a pro: they can hold a dangerous charge even with the power off.
