PF Motor
(Same as ASF/
Pump Motor)
Since "CR Motor" and APG Motor are DC motors, the resistance among the electric
poles varies. Therefore, judge if it is normal or abnormal based on if there is operation
of the motor or not; the resistance values cannot be used to judge the abnormality.
However, it is difficult to judge accurately, if it is not clear, replace the motor.
