Well, this is what's called anecdote. it's not definitive. Two techs...who now?
"The replacing this foam filter is not a part of normal service." Well, this is an inference derived from a phone conversation with two anonymous techs somewhere.
Racprops, you have a tendency to draw large, universal and definitive conclusions from scant or dubious information.
So how many witness do you NEED?? I talked to two CPAP repair service men.
Not a salesman, not a buddy, not some odd person I just called up.
I called two CPAP repair shops and asked if there was any foam in Resmed systems and both said no. Who else should I ask??
Then I was shown to the utube video right here and watched it in horror to see foam inside the fan housing.
I then called the tech whom has done service on my machine and told him of this finding and he said let me open it up and look him self.
Again I talked with a man whose job day in and day out is repairing these machines, again who else do I need to ask to make you happy??
And he said two things, OMG there IS foam in side this thing and I never seen that because we just replace the whole fan with its housing complete as that is what is send when we order a new fan.
So how about you watch the video and then call your repair shop tech and ask him to open the housing for you and tell you if there is foam inside. Or is your own known tech no good for you??
As for my "a tendency to draw large, universal and definitive conclusions from scant or dubious information."
Well I started repairing cars at 16 in 1965, and then was trained in A/C and heating repair and got my journeyman card in 1970, worked two summers and no winters then was trained in TV repair and service and repair TVs up until 1978, then I became a TV and Movie Prop maker and I still am.
I have been troubleshooting everything around me all my life. I now service my own cars with Fuel injection etc.
The ONLY THING I cannot repair is a automatic transmission, everything else I can and do.
SO I have been fixing and service things for 56 years. When a tech tells me has has never seen the inside of a Resmed fan that clearly means the replacement of the filter is NOT in any manual.
I think my 56 years of servicing and repairing all kinds of stuff should mean I have a good understanding of servicing stuff.
Good enough for you.
