When directly checking the operation of the fan motor
<Inside fan motor> (combi type only)
DC voltage confirmation from the control ASSY to the internal fan motor
Test result Judge
DC12V

6. CHECK POINT ＆ CHECK METHOD
Current value measurement with clamp meter between
input cord terminals.
Compressor is locked, or
contaminated. ※
※If the refrigerator does not cool down, or if the coldness is weak
◇Remove the fan motor coupler (white) on the compressor
side and measure the DC voltage between the coupler
terminals on the power supply side (Fig. 9)
◇You can check by directly connecting 18V to 24V DC, but
follow the precautions (Fig. 10)
◇Remove the internal fan motor coupler (black) and measure the DC
voltage between the control ASSY side coupler terminals (Fig. 11)
◇You can check by directly connecting 12V DC, but follow
the precautions (Fig. 12)
・Prepare a support coupler and perform measurement.
・ Be careful not to mistake the polarity.
To measure the rated current of the compressor, please measure after 15 minutes or more after starting the
