This step is required to replace the motherboard, side brushes, or beater bar motor. It can be skipped in most other repairs.

Remove the 5 silver 7mm screws retaining the motherboard and daughter boards.

Fold down the center daughter board and remove the hidden silver 10mm screw. This screw holds in the beater bar housing and can be skipped for other repairs.

Remove all of the cables connecting the motherboard to the rest of the unit.

There are some connectors underneath the left side of the board, marked in yellow.

Depending on your repair, you may not need to remove all or any connectors to access the necessary screws.
