Electronic Parts Troubleshooting Guide

Turn off Main Power

Turn on Main Power

Does "beeping" sound is made from the Indoor Unit?

Primarily, the operating condition of Micom is OK.

Check the voltage of power(About AC 220V/AC240V, 60Hz)

• Main power's voltage
• Voltage applied to the unit
• Connecting method of Indoor/Outdoor connecting

cable

• Check Fuse (Outdoor PCB Ass'y)
• Check Varistor

ZNRØ1J(Outdoor PCB Ass'y)

Check the connection housing for contacting

• Connector related to CN-DC/AC
• Display PWB Ass'y Check

Check each load(Indoor/Outdoor Fan Motor,
Compressor, Stepping Motor etc.) and contacting
condition of related connector

PCB Board Operation Check
