Is the indoor unit under group control?
Are the wires 1 (white) & 2 (black) to the remote control group
shorted or opened?
Is the wireless remote controller connected to on the indoor unit's
control PC board?
Disconnect the connector mentioned above on the board of the
indoor unit control PC board, and see whether the E02 goes off after
several minutes. (When doing so, if two remote controllers are
being used and the wireless remote controller is the main remote
controller, set the other remote controller as the main.)
Replace wireless remote control parts including wiring.
