S9 Blower Motor

[poppatm]

Hope that's how it works, but won't receive new blower motor until Nov 6.

Thanks, I had not realised that you had not yet received the new Motor.

Best of luck with it, and do please let us know how it went!

Received new motor 10/21/22.  This was actually quicker service from aliexpress than expected (est 11/06/22) in that I ordered the motor 10/11/22.  Motor works good and was easy to replace.  Since I am unable to reset time to 0.0 I just put a label on unit stating new motor at 23,723 hrs.

How did it go?

Were you able to reset the Hours, or did they reset automatically once the new Blower Motor was fitted?

I gather the ResMed units have a chip on the Blower Motor that stores the hours, so I think the hours move with the Blower Motor.

Such as, for example, if fitting a used Blower Motor with 4,000 hours into another ResMed S10 with, say, 6,000 hours then, once fitted, in theory, the hours would then change from 6,000 to 4,000.

If that is how it works, then fitting a new Blower Motor with zero hours, should change the ResMed S10's hours back to zero.

No idea if anyone has done this yet.

Hi there,

The Blower Motors are not fitted with a chip, so the hours would stay the same as recorded on the unit, even after replacing the Blower Motor.
I wonder if anyone knows how to reset the hours to Zero on an S9.

Edited: Just found this too ..... http://www.apneaboard.com/forums/Thread-...ower-hours

To Check the Run Hours on an S9 ... First press the 'i' button, you will see the sleep report screen.
Then hold down both the silver rectangular buttons until the little wrench appears on the bottom line.
Then turn the knob to the right of those silver buttons ONE click--you will see a different screen.
Press the knob to select the screen, then you turn the knob until the 'run hours' line appears.

Hello John!

I did wonder, because I cannot see any sign of a chip on the Blower unit. But have yet to take a motor apart to fully check.

I don't have one faulty enough to scrap, but may disassemble one that has known high hours and or is too dirty to use (I have a few used units, and would not re-use any with obviously dirty motors. Only those that look clean that I wash out with Isopropanol 99.9%).

So the hours look to be logged on the MotherBoard.

My main interest is for our own use, such as after fitting a new Blower, or if moving a Blower from one machine to another, I would want the hours to match the Blower.

I did wonder if the hours on a Blower moved with it if fitted to a different machine, but it sounds like they don't.

I may have one to test, which has a noisy Blower with known hours, and I have another Blower from an otherwise good looking machine that has suffered water damage that fried the MotherBoard, so I do not know the hours for that Blower.

If the hours change when doing that, I will update (may take me a while). I expect not but, if they do, I will let people know.

Yes the hours are recorded on a chip on the Main Board, nothing to do with the Blower Motor itself, so replacing the Blower Motor will make no difference to the recorded hours on the unit.

Hello John!

Many thanks, that does make better sense. I did think it would be logged on the MotherBoard, but had not seen it confirmed, either way, until now.

That is actually good to know, because I have been holding off playing with some of the used ResMed S10s I have, because I did not want to mess up the hours by accidentally swapping in a higher hours motor, so increasing the hours incorrectly and irreversibly on a lower hours machine, and then perhaps also triggering, say, the Hours Exceeded Warning (in case that shut down the machine, which I don't think it does, but wasn't 100% sure either way).

The first one I will swap is the burnt out machine's Motor into the one with a noisy Motor. That should make a working machine and, if the hours do change for any reason, I will update.

I also have a nice S10 For Her for my wife, that has high hours, and another machine that is scruffier, but has lower hours and what looks like a clean Motor, so those two will make, or should make, a good machine between them. Menu's are in French, which is a PITA but, still easy enough to understand.

It would be good to find a way to gain access to the MotherBoard configuration, I do have the interface, and am aware of the Airbreak hack (have that, but have never got around to trying it), but I don't think that helps in terms of getting at the standard configuration options.

That will need ResMed Service Centre Software of some sort, but it would be nice to be able to change Language, for example.

Hi there,

 The unit will not stop working after the "Motor Life Exceeded" message appears (S9 @ about 24000 hrs & AS10 @ about 22000 hrs)

Thanks John.
I got to 22,100 hours with my S9E. Now have an S10 *for her* with clock showing a year's use. I was wondering if it would do as well. It'll probably outlive me.
John are you a ham radio operator?

Hi there,

Both use the same Blower motor, the trick is to keep the dust out.

Yes I am a Ham Radio operator.
