Procedure
DC fan motor of the indoor unit (control chip is installed in the motor):
Switch on the voltage to the unit. In standby mode, measure the unit between terminals 1-3 and 4-3 of the
connector plug. Check the measured values against those listed in the table below. If these differ, there is a
problem with the control board and it must be replaced.

DC fan motor of the outdoor unit (control chip is installed in the motor):
Measure the resistance between terminals 1-3 and 4-3. This should be roughly identical. If the resistance
deviates significantly, assume that the motor is defective and must be replaced.
