ResMed S9 fan motor rubber belt faulty
#1


I'm new to this forum, but have been using a ResMed S9 since September 2011. The first machine I returned to the supplier Apria when I woke up with my mask and breath through cloth covering on. I went into the bathroom and from the mirror saw black smoke fanning out like rays of the sun from the mask. I took off the mask and cloth and found the cloth I was breathing through too was "dirty".

I made and appointment and went to Apria in Cromwell CT. They promptly offered another S9 as a replacement May 2012. They promised to let me know what the problem was. I waited a month then called to find the answer not forthcoming but was promised a return call. Over the year I made several calls all with a promised call. Finally I called and said maybe a lawyer would help get a response. My next call I was referred to their legal departments phone #. OH Boy what a pain.

So here I am going through a Stem Cell Transplant at Sloan-Kettering and what happens yup you guessed it I smell rubber after taking off the mask and letting it run for a few minutes. Again I call Apria telling them of the possible fan belt problem and again they offer a new S9 unit. No questions no referrals to the legal department.

So I ask the group have you ever inhaled the black rubber from the fan belt in the Res Med S9 unit? Most people would sleep through it I guess. but for these units it seems problematic after a year of use or so. I feel grateful of having been warned first by the bathroom mirror (i took photo's) and now just by smell after the machine was running with no face on it.

So I hope this helps the group to be on the look out. Please share any similar stories.

I have had the black mask liner problem too. I believe it was from burning a candle with the wicks not trimmed properly. Only happened once, am using the same machine with no issues.

Just something to consider, am not sure if it applies to you situation.

I hope your issue is resolved soon.

Just curious- how do you know there's a fan belt? Seems a bit odd that a blower with an integrated DC electric motor would need one. Also hard to believe they would put one in a respiratory device.

Excellent question. Isn't the motor direct drive?

I'm not allowed to post links yet since I just joined, but perhaps someone else can add this. Doing a Google search on the keywords "resmed fan belt" brings up a document titled "ResMed Origins" (second hit). It seems to be a lengthy history of the company.

On page 18 there's a reference to a switch in motor design from a belt-driven one to a direct drive DC motor. That happened in the 1980's.
