5.2 Indoor Fan Motor Connector Check
Check No.03
Fan motor wire breakdown/short circuit check
1. Check the connector for connection.
2. Turn the power off.
3. Check if each resistance at the phases U - V and V - W is within specified range in the table
below.

5.3 Power Supply Waveform Check
Check No.11
Measure the power supply waveform between No. 1 and No. 2 on the terminal strip, and check the
waveform disturbance.
Check if the power supply waveform is a sine wave (Fig.1).
Check if there is waveform disturbance near the zero-cross (sections circled in Fig.2).
