Why is my Panasonic CU-L43DBE5 Air Conditioner showing an F27 error?

The issue may stem from an indoor/outdoor unit disconnection or connection error. Check the indoor/outdoor unit connection cable and connection terminals, and verify the power supplies on both the indoor and outdoor units. Also, inspect the indoor/outdoor unit connection wire on both the indoor and outdoor sides.
