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

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

Remove the 14mm Torx T10 screw that is located between the air outlet and the front screen.

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?

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

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

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

Where can i buy a replacement pump?

Shayne Braid - 24/02/21

Alibaba sells the pump. Everyone else is OOS.

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 -

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!

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!

- 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.
