Remove the electrical component box cover (4 screws). Disconnect all cords that run into the electrical

component box. Next, remove the screws (2 each on the left and right sides) that fasten the electrical

component box and remove the electrical component box.

The PCBs are arranged as shown in the figure below. When removing the power PCB or fan PCB,

first remove the control PCB mounting bracket (4 screws) then remove the power PCB or fan PCB.
