2.Troubleshooting procedure

When a trouble occurred, check the parts along with the following procedure.

Trouble

→

Confirmation of check code by service mode

→

Check defective position and parts.

NOTE :

For cause of a trouble, power conditions or malfunction/erroneous diagnosis of microcomputer due to outer noise is considered except the items to be checked. If there is any noise source, change the cable of the signal line to shield cable.

(a)Outline of Judgment

A primary judgment to detect cause of error exists on the indoor unit or outdoor unit is performed in the following procedure.

The indoor unit monitors operating status of the air conditioner, and if a protective circuit works, contents of the self-diagnosis are displayed with a block restricted to the following cases on the indoor unit display part (Sensors).

Remote	Block display	Contents of self-diagnosis	Check code
controller code	Block display	Contents of self-diagnosis	Check code
controller code

—	Operation lamp display flashes. (1Hz)	Power failure (In power ON)	——

00	Operation lamp display flashes. (5Hz)	Indoor P.C. board	0b to 0F, 11, 12, b5, b6

01	Operation/timer lamp displays flash. (5Hz)	Inter-unit cables/transmission system	04

02	Operation/defrost lamp displays flash. (5Hz)	Outdoor P.C. board	14 to 19, 1A, 1C

03	Operation/timer/defrost lamp displays flash. (5Hz)	Cycle system, etc.	1d, 1E, 1F, 21

—	——	——	1b, 8b

(b)Self-diagnosis by check code on the remote controller

In the wireless type models, the self-diagnosis for the protective circuit operation is performed by handling the remote controller. First change the operation mode of the remote controller, and then perform the self- diagnosis by the displayed contents of the remote controller and the existence of operation lamp flashing (5Hz) and buzzer sound (Pi, Pi, Pi). During self-diagnosis operation, the timer lamp usually flashes (5Hz).

•Selection of remote controller operation mode

1)Selection of service mode

Push the select button at lower side of the wireless remote controller with a tip of pencil, etc. for approx. 3 seconds or more. In this time, check that [00] is displayed on the room temp. display part and other displays go off.

2)Selection of normal mode

Push the reset button at lower side of the wireless remote controller with a tip of pencil, etc. In this time, check that [“AM”] display on the time display part flashes.

‚Cautions in service

1)After service work, be sure to push the reset button to return the mode to normal mode.

2)After service by the check codes, turn off the power switch once and then turn on the switch to return the stored memory in microcomputer to the initial status.
