3 Remove the 6 screws of the front panel.

4 Push the front panel and lift the shield plate to unfasten the hooks.

Warning: This procedure should be performed by a trained technician

Measure the power supply waveform between No.1 and No.2 on the terminal board

Upload a photo of the measured waveform

Is the power supply waveform a sine wave?

Is there waveform disturbance near the zero cross?

Sign off on the power supply waveform check

Output voltage between pins 1 and 3

Number of pulses generated between pins 2 and 3 when the fan motor is operating

If NG in step 1, what is the defect?
