    MODE CONTROL ACTUATOR SPECIFICATION

    Door position Voltage (V) Error detecting
    Vent 0.45±0.15 Low voltage: 0.1V or less
    High voltage: 4.9V or less
    Defrost 4.55±0.15

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

  7. If the measured voltage is not within specification, substitute with a known-good mode control actuator and check for proper operation.
