Oxygen Concentrator troubleshooting

[otldzign]

I am hoping that someone else has had this happen to them and can give me some advice as to what I need to do.

I have a Devilbiss 505DS oxygen concentrator that I've had for about 2 yrs. Today when I went to torch, I opened up the oxy valve on my torch and turned on the machine....like I've done so many times before. The flow meter ball did not rise up and seems to be stuck on the bottom at 0. When I turned the machine off the last time I used it about 3 wks ago, I turned the knob down so the ball was at about 1 LPM and then turned it off. I had expected that this is where the ball would have floated to today. I have done this so many times before, I don't even really think about it. The unit seems to be running fine and the 'Service Required' light does not come on nor does the warning beep sound....so I'm guessing that's a good sign. However, the flame on my torch doesn't seem to be as hot as normal.

Has anyone had this happen to them? Any suggestions?

I am sure hoping that I don't need to send it in for repair. ](*,)

Thanks in advance for any help!

Can you get the ball to go up to 5 LPM if your torch valve is wide open?

Where was it stored for the three weeks that you did not use it? Was it anywhere where the temperatures dropped really low?

Hi Kimberly,

I open the torched wide open and the ball does nothing. My studio is in the basement and that's where all of my equipment is. It is generally above 60 degrees down there, though. I may have spoke too soon about the Service Required light and the warning beep. ARGH. I left the concentrator running....hindsight, maybe not the right thing....but about 1/2 hr ago, the warning beep started going off and the Service Required light is lit. Of course, wouldn't you know that it's no longer under warranty....and I live in 'BoDunk' so I'm not sure if I'll be able to find any local repair shops to fix it. Perfect timing....I guess my friends won't be getting the icicle ornaments that I had planned for Christmas gifts. ARGH again!

If anyone has any additional suggestions as to what it could be, I'm a pretty good DIY'er....

I am guessing you turned the knob back up to 4 or so when you turned on the machine.

I have a Devilbliss that has malfunctioned also. I think it may be the same model, I didn't check. I called Jay from Precise Bio where I bought it and he said it sounded like a valve needed to be replaced (which he's supposed to be sending.... guess I have to call him AGAIN). Do you have a warrantee on yours?
