11. Timer lamp blinking: blinking 12 times
[Situation] The timer blinks 12 times and the product will not run.
[Estimated failure locations]
䊶
Erroneous connection in the indoor-outdoor connection line (F cable)
䊶
Wire break or poor insertion of the indoor-outdoor connection line (F cable)
䊶
Electrical parts in the outdoor unit (communication circuit, power circuit error)
䊶
Communication error due to noise in other home electronics
㶎
This does not constitute a failure in the air-conditioner
[Cautions]
䊶
When lines 1 and 2 of F cable are erroneously connected (crossed), the product may not
enter self-diagnosis display mode. If the self-diagnosis memory stores data about "timer
lamp blinked 12 times", then, just in case, check if the F cable is not erroneously connected.

Correct the F cable connection.
Is the CN securely inserted into
the outdoor board?
Correct the connector.
Press the START/STOP button on the remote control
unit and start the product.
Are terminals 1 and 2of the terminal board of the
electrical parts of the outdoor unit subjected to
㶎
Take measurements within 3 minutes after remote
control operation.
Check the electrical parts of the
outdoor unit.
Are terminals 1 and 2 of the terminal board of the electrical
parts of the indoor unit subjected to
220-230V ?
㶎
Take measurements within 3 minutes after remote control
operation.
Double-check the F cable for erroneous connection,
wire break and poor insertion, and correct the
nonconforming parts.
Replace the "indoor control P.W.B".
