Step 1 — Roller Brush Compartment
Pop out the two small wheels located on the front end of the bottom of the roller brush compartment.

Step 2
Remove the 10 Phillips screws located on the bottom of the roller brush compartment. (Two of these screws are located under the wheels from the previous step.)

The screws have varying lengths, so keep track of where each one goes for reassembly.
Step 3
Remove the white plastic cover to expose the roller compartment underneath.

Step 4 — Motherboard
There is one screw at the edge of the circuit board. Unscrew the circuit board before attempting to take it out.

Component labels observed on the circuit board include: 48VDC-1200, 10A 277VAC, 12A 125VAC, CHINA, TN14J, FURJA, FJ 7.820.186(A), OGABY, ACI.
Step 5
Take out the circuit board and replace with a new one. It may be better to allow a professional to re-wire the circuit board to the vacuum.
