Common Failures

Failures of the air door actuators often lead to the air door becoming stuck in one position, leading to improper ventilation.

Electrical Failures:

  • Motor Failure
  • Poor Electrical Connections
  • Internal Electrical Components on the PCB fail

Mechanical Failures:

  • Broken Gears
    • Split in the main drive gear
    • Broken teeth on small gears

Functional Failures:

  • Internal feedback for the actuator's position no longer functions properly, often resulting in an intermittent failure
