Introduction

The ResMed S9 VPAP Auto is a medical ventilator, commonly referred to as a VPAP (variable positive airway pressure machine). This guide will direct you to access and replace the blower within the device. The blower is used to cycle air through the device, circulating air through the filters and blowing the air through the hose and to the user of the device. When the blower malfunctions, the device will not be working. There will be no circulation through the filters and through the device. Replacing the blower with a new or functioning one will completely fix the problem. For more information on the device, go to the manufacturer’s home page.

While removing the top panel to access the motherboard, be careful not the apply pressure to the side of the control knob. It has been known so snap off due to an impact or to pressure.

Tools

Step 1

Flip the device upside down.
Use a T3 Torx screwdriver to remove the screw in the corner.
Each screw in this guide is a 1.2 mm Torx T3.

Step 2

Use a spudger to pry off the back panel.

Some more clarity on how to do this would help. I'm afraid of breaking plastic by prying the wrong direction or the wrong location.

Step 3

Use the spudger to pry off the front panel.
If you are having difficulty, press the two hooks to open that side of the device.
Remove the front panel to expose the internal components.

Step 4

Remove the two screws on the circuit board with a T3 Torx screwdriver.

Step 5

Remove the plug connecting the red, orange, and black wires to the control board.
The plug in the top right corner is accessed through the bottom of the device.
Flip the device upside down and use the tweezers to squeeze the plastic release for the remaining cable.
The control board will then lift right off, exposing the interior of the machine.

Step 6

Remove the five screws from the frame using a T3 Torx screwdriver.
Lift off the plastic frame to expose the blower housing.

Step 7

Remove the silicon ring around the blower.
Lift the blower out of the blower housing.

Do you know the part number of the blower?

Where can I buy the Resmed S9 replacement motor once we can’t open it to clean?

Actually- the motor in your picture is the wrong way! It is upside down! It only seals the correct (opposite) way.. !

I didn’t see a link to the manual on this guide. It would be helpful as would the part number for the blower. Thanks!

I just completed this repair with a new blower motor from www.advanscpap.com and was very easy. They actually sent the complete lower housing with the blower motor which makes install simpler. Didn't need the last two steps of this tutorial. Also, a slight correction to this tutorial; the driver needed was a T10 and not a T3.
