    Vent 0.3±0.15 Low voltage: 0.1V or less
    Defrost 4.7±0.15 High voltage: 4.9V or more

    It will feedback the current position of the actuator to controls.

  7. If the measured voltage is not within specification, replace it with a genuine mode control actuator and check for proper operation.
  8. Replace the mode control actuator if it is proved that there is a problem with it.
