Remove failed fan

You remove a failed fan so you can replace it with a new one.

Before you begin

Procedure

  1. Remove the controller canister's cover by unscrewing the single thumbscrew and lifting the lid open.
  2. Confirm that the green LED inside the controller is off.
    If this green LED is on, the controller is still using battery power. You must wait for this LED to go off before removing any components.
  3. Gently lift the failed fan from the controller.

After you finish

Go to Install new fan.
