6.2.3. Step 3: Remove failed fan
You remove a failed fan so you can replace it with a new one.
Steps
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.
