ResMed AirSense 10 Pump Motor Replacement

Difficulty

Moderate

Steps

Time Required

50 minutes

Introduction

This guide includes a complete teardown to reach the pump motor for cleaning or replacement. If the unit was bought seconded hand, this guide will allow the user to check and clean all the parts in the ResMed AirSense 10.

Tools

Step 1

Position the ResMed Airsense 10 with the water reservoir facing towards you.
Grip both the top and bottom of the water reservoir and pull it straight out and away from the device.

Step 2

Position the ResMed Airsense 10 with the screen facing you to remove the front cover plate.
Place your finger under the indent beneath the home button and pry the front cover plate off.
This should only require medium pressure.

Step 3

Remove the two 14mm Torx T10 screws that were exposed by removing the front cover plate.

Step 4

Rotate the device to face the bottom of the ResMed Airsense 10.
Remove the four 10mm Torx T10 screws, then place the screws and the plastic heater plate cover to the side.
Remove the remaining two 14mm Torx T10 screws.

Suggestion: The 4 screws for thermal do not need to be removed to access the motor nor the connector to thermal be removed. Only remove the two screws 14mm long opposite to the 4 10mm screws

Step 5

Once you have removed the cover of the heating plate, disconnect the orange wire from the fuse.
Carefully pull the orange wire through the silicone gasket.
Fully remove the heater plate from the ResMed Airsense 10.

Step not needed to reach the motor

Alain Butzberger - 23/02/21

Please remove this step as that it is not neccessary to complete this work

Steven Hicks -

Step 6

Remove the remaining two 14mm Torx T10 screws holding the frame together.

Step 7

Orient the ResMed AirSense 10 to face the rear of the machine. The air outlet should be facing towards you.
Use the plastic spudger to pry the casing of the ResMed AirSense 10 off of the unit.
Fully remove the casing from the ResMed frame.

Step 8

Position the ResMed AirSense 10 with the screen facing towards you.
Carefully remove the 4 pin wire connector located to the left of the screen.
Fully remove left panel of the ResMed.

when removing this clip lift up from the wire side slightly then gently pull out.

Thom -

Please add the direction where force should be applied. I broke the connector because this visually looked like it should slide outward.

Steven Hicks -

The connector on the other end is a lot easier to remove, on side panel

adquezada -

using the plastic spudger is great way to get under the wire and pull up. This wire does not pull laterally like the first wire. This one pulls out vertically.

Some Dude -

Step 9

Position the ResMed AirSense 10 with the air outlet facing you.
Remove the 14mm Torx T10 screw that is located between the air outlet and the front screen.
Remove the wires from the pump casing's hook.
Carefully start to remove the pump casing from the Resmed AirSense 10 until the wire connector is exposed.

lever the motherboard out slightly when removing the pump

Tracy White -

Step 10

Unclamp the connector for the wires that connect the pump casing to the motherboard to fully disconnect the pump.

when reassembling make sure the tank slides onto the rail at the bottom

Tracy White -

Step 11

Orient the pump casing with the wires facing towards you.
Unhook the wires from the outer most clip.
Then remove the plastic retainer from the pump casing.

Anyone know the air pump part number or where I could get one?

Timothy Belleson -

The same pump is used on the ResMed S9, S10, Airsense 10, and Aircurve 10. I got mine from a Chinese company named Vorgens that sells off of Amazon as of November 2024. It weighed an ounce more than the removed OEM blower and seems solid.

Alan Prill -

Step 12

Remove the blue silicone buffer to right corner.
Remove the wires from the remaining hooks.

Step 13

Orient the pump casing to face the outlet port.
Push the outlet nipple into the pump housing.

Step 14

Orient the pump casing to face the three T10 torx screws.
Remove the three 14mm Torx T10 screws.
Lift off the top of the pump casing.

There is a round foam piece that goes on top the pump before you put the top back on. Make sure to put that in before putting the top back on!

bobthemacdaddy -

Thank you for this note, as a week had passed since removal and I could only guess where it went. There is a cutout or indentation in the foam disk that allows the pump wiring by. This is an important filter and should not be forgotten!

Alan Prill -

Step 15

Remove the pump assembly from the pump casing and face the pump assembly with the mounting plate facing you.
With the pump assembly out of the pump, there is a mounting plate that needs to be removed to access the pump.
There are 5 rubber ridges connecting the mounting plate to the rubber sock encasing the pump.
Push the ridges through the holes in the mounting plate.

Pushing in the rubber ridges are easier with the plastic spudger.

Some Dude -

Step 16

Separate the mounting plate from the rubber sock.

Step 17

Pull off the rubber sock to expose the pump.
Do not damage the wires while removing the rubber sock.
The exposed pump can now be cleaned and inspected for damage.

Hola, soy de Chile y necesito comprar un motor para reemplazar el que está averiado y no aparecen proveedores, si es posible publicar alguno estré agradecido

Can the motor itself be disassembled for deep cleaning? My wife took hers on vacation with us and now it's got an unbearable febreeze smell we can't get rid of. I disassembled everything except the motor itself and thoroughly cleaned all the components like you advised, so the only culprit left is the motor itself. Any suggestions?

Larry -

I have a brand new motor for sale. My cost was $238.00. Interested? Mike.whittemore@hp.com

Timothy zBelleson -

This is the supplier I used. I also will validate that the replacement worked for me.

Steven Hicks -

How do you reset hour meter on the Resmed Airsense 10 after you replace the motor?

Fred Franks -

Hi Jasey, did you ever open the pump motor itself? I got a cpap machine that must have been in a fire. The maschine is ok but everything was full of soot particles, I was able to clean neary everything but the pump motor ist glued together and I dont know if the motorcase breaks if I open it nevertheless with a knife or sth.

A tipp is appreciated, cause a new one from C costs 95$ and I prefer not to buy in C if possible.

Thanks Chris

Carl Haupt -

Here is a description by someone who managed to open the motor:

Thank you @jaceyt ! This was spot on.

Where can i buy a replacement pump?

Shayne Braid - 24/02/21

Alibaba sells the pump. Everyone else is OOS.

Travis Verner -

got mine from aliexpress, but they are also on amazon

Tracy White -

Where can i buy replacements?

christecnico - 07/04/21

Step 1, find a replacement motor???

jglazer - 20/04/21

The AirCurve 10S looks very similar. Is motor replacement in this unit the same process.

Bob R - 22/04/21

The problem isn’t so much the steps here (but, thanks—I found this after I had done it). The problem is that the clear-plastic fan/motor case cannot be cracked open for cleaning (as near as I can tell). I cleaned as best I could reach with a Q-tip, but to no avail. So, replacement is the only option. :-(

Russell Bateman - 30/04/21

Where or how does one acquire the replacement motor/pump assembly? I have looked at every ResMed supplier website I can find with no success.

bmw-ktm -

ali express or amazon

Tracy White -

Where can you actually find a motor? My friend REALLY needs one.

Geoffrey Van Horn -

I replaced the motor with a guaranteed Resmed Original part, but the machine ran alot quieter but was lazy under load. Has anyone got any suggestions. This sounds like built in obsolescence……………………….in the software???

scottcon -

what was the source of the replacement ? Resmed seem reluctant to provide.

dave jones -

Where may I purchase a new motor for ResMed AirCurve 10 s?

Melanie Knupp -

What is the large blue connector on the other side of the SD card? Any way to reuse any of the parts for other projects?

ba600 -

I found Jacey Cobb on facebook a couple of months ago and contacted him to learn where he got a motor but he has not replied. If anyone knows where to acquire one I would be very grateful.

bmw-ktm -

Is this possibly the cause of a loud whining noise that ramps up and down as you breathe? It definitely sounds like an electric motor ramping up and down.

Rocco Williams -

Mine died a slow death of loud screams over 3 weeks. Looking for replacement motor, but have not found it anywhere. Recall hampering my replacement as it’s just out of 5 years. I’m turning gray again, I too any dying a slow death!

John D’Ginto -

Now, due to ‘COVID’ the supply chain leaves these ‘backordered’ and still can’t find parts, like, the motor. Has ANYONE located parts? There Ought To Be A Law!!!!

PCARRINGTON -

Whining noise started on mine in September, tore it down to clean but also found I couldn’t open the motor casing to deep clean or replace bearings. Spent next 3 weeks waiting for dr. appt. as Apria told me I needed a new prescription before they could replace it. By the time all paperwork got back to Apria, I was put in queue behind many others waiting for machines, was told 6to8 weeks(from 11/15). Followed up yesterday to make sure I was still in queue,was told it could be another 4-6 weeks.

Currently have machine in a plastic box surrounded by pillow bunting inside, with outside wrapped in 2 blankets. Holes cut for Hose and Power Cord. Whining noise still penetrates all that, keeps us both up at night.

Very frustrating that replacement motors are not available anywhere, and that motor casing cannot be opening to clean inside. Now considering using a Dremel to cut the plastic casing open and then Super Glue back shut after cleaning. Ridiculous, feel like I’m in 70”s USSR or current Venezuela!

Where to get its motherboard

John Mohd -

Any idea about its motherboard?

where can i buy replacement moyor

George Dixon -

Found this listing for a “new” motor. Unfortunately more than I’ve got to spend at the moment. Hope it helps someone else though.

Corey Jackson -

is the RESMED Air Sense AirCurve S10 Motor and the AirSense 10 AutoSet the same?

Tony Goold -

This guide needs to be adjusted when describing what directions to pull the wires. A connector from the modem to mother board broke because it was pulled the wrong way.

Steven Hicks -

If you own a ResMed AirSense, you may follow the detailed instructions here to swap out its pump motor. The text is well-written and includes detailed instructions with illustrations. If you need to fix your CPAP machine, this piece, written by what seems to be an expert, will be a big assistance.

Ottime foto. Cambiato la pompa delle mia Resmed Airsense10 Autoset con una ordinata da Aliexpress. L'unica difficoltà che ho avuto è stata il punto 8: staccare lo spinotto..magari potevi spiegare meglio come fare. Per il resto top!

Geo Chiesi - 25/02/23

- Under "Introduction" the reader should be reminded to use the Magnifying "+" glass that can be seen when we hover the mouse over the picture. Step 8 would take advantage of the words "EXTREMELY CAREFULLY ..." as this connector is EXTREMELY FRAGILE. "Only extremely gently push the black connector out" (to the left on the picture). The maximum enlargement of the left picture on Step 8 MUST BE SEEN. The glove hides part of the connector. A movie and more details on the precision gesture needed for removing it without damage would be welcome.

- My unit gives a message to the effect that the motor has run passed it's maximum life (I used it more than 20k hours) ... but this is no problem, it still works fine.

N.B.: When I reached the motor, I decided not to go any further skipping Steps 15-16-17. I could see that the inside (blower) was not very dirty (definitely not disgusting) and that for an occasional usage (2nd bedroom) it could stay the way it was. Upon reconstruction the unit worked fine.

Thank you.

Michel -

Does anyone know how to reset the Unit Usage Hours (Motor Used Hours Count) ?

Michel -

The job went well after fixing a few whoops during reassembly. What I can't figure out is how to reset the timer now that there is a new motor in the CPAP. You might want to let your viewers know how to do this. I plan to just ignore the warning now that I know there is a new motor in my machine.

Sulo Vaisanen -

@jaceyt this was a beautiful tutorial, very helpful. Thank you. Now I just need to find the part number for the replacement pump motor.

RJ Carmine Glorso -

Where can you find parts for the device. Disassembly is great but . . . If parts are not available, what’s the point?

phudson38 -

Great guide. Thanks.

Bruce Russell -

There is no need to do anything with the heater plate when replacing the motor. Skip that step. Be sure to replace the blue air sensor ports when re-assembling the unit.

gcoxjr -

This really helped, as did a YT video. Between the two it was ‘cake’!

My biggest tip is to note part orientation during disassembly so you can put it back more easily.

I guess that advice goes for most things we fix!

AtlantaMan -

Quick note: it is late in the game, but the motor is the part you’ll want to replace.

Motors are available on AMZN, Alibab, and some other ‘outside’ sources — CPAP shops don’t sell them, and in-channel parts suppliers don’t deal with Users, just registered repair firms. The repair guys might put one in for you as a repair, but it would really be costy, and they don’t sell the motor as a separate part.

My motor went bad: it got extremely noisy over time. The bearings were shot but upon external inspection it looked fine. I dissected an old S9 that worked ok to get a motor to swap into the s10, but the old motor (nearly identical) was filled with dark colored dust —from its operating environment I guess. I read the motor swap would have worked otherwise, but they really can’t be opened and cleaned.

AtlantaMan -

Great guide! My AirSense 10 starting making a whining noise. Ordered a pump from Amazon. Crazy how dirty the innards of the thing were. Really scary. Washed all plastic components with Dawn dish soap. Went back together really smooth!! Thanks again.

James Judd -

https://a.co/d/ct4McBV

Is the part I found on Amazon. Fit perfect!

James Judd -

My ResMed Air Sense 10 is still going OK and not noisy but it keeps popping up with" Motor Life Exceeded" contact care provider.

Should I be alarmed will it stop working?

Jonno41john -

Does anyone know how you rest the "Motor has exceeded it's life expectancy" if you change out the motor for a new one?

stagebuilder -

FYI from another website:

The only way to reset the total hours and motor life warning
is to send it to a factory authorized service center ..
Supplier 28 on the list can and there are others listed ..
But they may want to do the work also ..
I believe they recalibrate sensors and other work before they
reset a machine ..

stagebuilder -

Another great guide to fix instead of waste a otherwise good device/appliance.

Just one comment, guide is missing mentioning the foam piece on top of the pump casing. I missed re-installing the foam when re-assembling the unit with the new motor because I was following the instructions in reverse, forgetting about the foam.

Adding a pic with the foam should be enough to point out to people to put it back again.

scl -

J'ai changé le moteur et tout fonctionne bien mais le message d'erreur s'affiche encore comme Fin durée de vie turbine.

J'ai appelé un réparateur accrédité ResMed et il me dit que je dois REFAIRE calibrer mon Cpap et il dit qu'il doit vérifier plusieurs senseurs dans la machine pour s'assurer que tout est ok à cause que j'ai acheté un moteur sur internet ?

Stephan Gagnon -

On a installer la nouvelle turbine et elle inscrit encore fin de vie pour ma turbine que faire merci

daufin222@hotmail.com -

Dans ce cas, il vaut mieux contacter le SAV du fournisseur de la turbine. Peut-être qu'il y a une calibration à faire ou bien la pièce est défectueuse.

Claire Miesch -

Bought a replacement motor from Amazon. Instructions were great! My machine is quiet once again. I just wish Resmed would make the original parts available!

Phillip Davis -

J’aimerais savoir si après le changement vous avez encore le message de fin de vie de la turbine

Sylvain Scott -

Excellent guide, except for the foam ring that sits (I assume) on the top of the motor. It took me around 20 minutes to replace my original motor with one I bought on Amazon.
