How do I access the motor on a Resmed S7?
Hi all. I'm new to the forum. I've already searched for what I need, but didn't find it anywhere.

I have a 4 years old Resmed S7 CPAP. This week, it started to make a really awful noise. The machine that was supposed to make me sleep well is keeping me from sleep! So I took it to the shop and they said the problem is in the motor and they don't have that kind of motor anymore.

Well, I could as well buy a new machine, but I was thinking about trying a DYI approach to the problem. So I opened it uup just to find out the motor is sealed inside a plastic case. Does anyone know if there's a way other than brute force to open this case and access the motor? I want to try and clean it, maybe replace some bearings and see if it works.

Thank you all in advance.

I don't know how to get into the motor, but are you sure it is the motor? What if the fan came loose or is wobbling?

If it is the bearings I doubt you will be able to fix it. For sure Resmed will not sell parts to an end user. You might check the Supplier list here (there is a link at the top of every page on Apnea Board). A couple of them do repairs. Worth a phone call. Otherwise, you can hope that the bearings are standard so you can buy from a bearing supply store.

Considering the age of the machine I would consider getting an up to date replacement. I got an S9 Autoset from Supplier #2 for $859 with free shipping, a top of the line machine that is data capable. But if money is an issue I understand. There was a recent thread here about organizations that help people who need CPAP and are without money or insurance.

My bet is that the motor has no bearings at all. Most likely they are bushings and they are just worn slap out.
If you can find a compatible motor with ball bearings that will likely last you until the machine's electronics die.

Go ahead and take it apart. It's already broken anyway, right?

Good luck and take photographs!

RE: How do I access the motor on a Resmed S7?
This response is a "better late than never" one but.....

I've been using an S7 since 2004. The blower was gradually getting louder as time and usage cropped up. I'm also a CBET (certified biomedical equipment technician) with over 20 years in the field including ventilators and anesthesia systems. They still would not sell me the blower! But I had my mask provider in Denver send Resmed the unit for evaluation. Resmed charged me $125 to replace the blower with a new one. I thought this was a reasonable price, and a lot cheaper than a replacement.

I hope this helpe someone with an S7 in the future.

Found an old thread with instructions for disassembling the S6 motor. Maybe it's similar enough to help you.

Do at least pressure-test the unit before using it if you do any modifications. Smile
