Question about LG Heating & Cooling
What causes error code 5? The inside unit is not communicating with the outside unit. Why does this happen? The unit is less than 6 months old.

I don't know if this is the proper technical solution or not but my unit was having the same issue. I cleaned it checked fuses made sure the cover was properly in place and nothing worked. As a final thought I went to the home fuse panel and tripped the breaker for the unit, waited about 30 seconds and turned it back on. I did this with the unit set to off. When I came back and turned it on, it is working properly with the operation light solid red.
