Lost knob for Resmed S9
I lost the knob for my Resmed S9, Resmed says I have to go to my provider; big hassle. Any other ideas where I might get one?

Thanks!

RE: Lost knob for Resmed S9
Where's that photo of a disassembled S9? I think that knob has a 6mm shaft. I don't recall if the shaft is round or D shaped.
(I think it's D shaped with a push on knob)
You can likely make a potentiometer, 6mm knob work. I'd look for one with a set screw.

Since the knob is dual function -- both turn and press, the depth of attachment is critical. That's where a set screw might let you fix the position on the shaft.
Look for them online as 6mm potentiometer knobs -- or, if you have a friend who has been into electronics for a long while, likely they would have a knob that could be made to work.

BTW -- how did you lose it?Eat-popcorn

RE: Lost knob for Resmed S9
You might check with some of the suppliers in the supplier's list. #18 has been responsive to e-mails in the past, although it wasn't a "repair" part like the a knob.

Get the free SleepyHead software here.
Useful links.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.

it's splined no set screw, just press on. I'd have to find my caliper to get a measurement... and it seems to have buggered off.

Try a surplus electronics store, if you can find one in your area. There are a couple of them in my city. They have bins full of all kinds of knobs.

Plenty of 6mm splined knobs at that online company run by Bezos.
6mm (approx 0.25 inches is a very common shaft size.)

A post elsewhere makes me think Supplier #17 may also be good for repair parts.
