Why is my Panasonic CU-RE28PKR not communicating between indoor and outdoor units?

Abnormal communication between the indoor and outdoor units of your Panasonic Air Conditioner can occur due to several reasons. It could be a faulty indoor or outdoor unit PCB, a wiring error between the units, or a broken wire in the connection wires. To resolve this, check the indoor unit PCB, the outdoor unit PCB, the wiring between the indoor and outdoor units, and inspect for broken wires in the connection.
