Unplug your air conditioner

The air conditioner needs to be accessible from all sides

Be careful not to touch the evaporator and condenser (front and back) radiators with bare hands! They are very sharp!

Unclip the white filter cover

Fold the filter cover all the way out

Apply slight downward pressure to unclip the 4 arms holding the filter cover in place

Take out the dust filter by bending it down past the two clips holding it in place

Unscrew the 2 screws holding the front panel in place

It won't come off yet, don't worry that is a later step

Unscrew the two circled screws

Do not unscrew the bottom screws, they hold the base on

Unscrew the two marked screws

You do not need to unscrew the bar (marked in green)

Unscrew the 3 left and 3 right side screws

Slide a pry tool between the front and top panel, bending the front panel out and forwards until the front panel comes off

Boxed in yellow in what the clips look like

Front panel should now easily come off

Top panel should now easily come off

Congratulations! You now have access to the internals to clean/repair/replace as you need.
