If you mean Control Knob and
You have a 60 series machine,
then https://www.cpap.com/productpage/pr-cpa ... ob-ui.html

It may fit a Series 50 but I can't tell from the web page.

But, it may be that its not the knob but the switch the knob is on.

how are you at desoldering? the pn of that rotary encoder may be printed on the side or bottom.

I'm not great at soldering but I get by. There are 7 places that the switch is soldered to the board

unless the new board you're getting sent works for your machine (heck, it might be an upgrade!) you'll have to remove the old encoder and put the new one in. removing the bad one isn't too hard, you can just clip it off, but you have to use a solder sucker or solder wick to desolder the new one without damaging it.

might just be dirty , try cleaning it with an air-sol can of electrical cleaner ... get from radio shack
If you're not part of the solution you're just scumming up the bottom of the beaker!
