Troubleshooting Procedures
!WARNING
To avoid risk of electrical shock, personal injury or death, disconnect power to unit before servicing, unless testing requires power.

MOTOR TESTING
A motor test cord may be used to electrically check operation of the various electrical components without removing them from the unit. Testing in this manner merely determines whether or not part will function independently of other electrical components. In order to make accurate test, proper connection of the motor test cord is important.
All four leads of the test cord are required to test the washer drive motor. The following drawing shows installation of the test cord on washer drive motor. Reversing the motor from agitation to spin is accomplished by reversing the test cord wires B and C.
