4. If the incline moves normally skip to step 7.
5. If the display indicates that the incline should be moving and the incline motor does not
move and AC line voltage is present, skip to step 12.
6. If the display indicates that the incline should be moving and the incline motor does not
move and AC line voltage is not present, replace the power control module.
