Before removing the blower motor assembly, peform an on-equipment test to determine if removal is necessary. Test the motor for resistance with a multimeter set on the ohm scale as follows: (1) Touch the multimeter leads to the pins in the receptacle connector. The 400 Hertz motor assembly should indicate about 2.25 ohms. The 50/60 Hertz motor assembly should indicate about 4.7 ohms. (2) Connect one multimeter lead to the motor assembly frame. Connect the other lead to any of the three receptacle pins; no continuity should exist (O reading). 3-11
