RE: Machine turning self off and back on
I replied in the other thread. The most common reason for this failure is when the flow sensor in the upper-right corner of the main board fails to detect breathing. This was fixed in later generation Respironics machines (Series 60) by adding a screw to the main-board to maintain contact of the sensor with the breathing circuit. The 550 can be repaired by adding a #8 X 1/2 sheet metal screw with a plastic washer to the empty mounting hole about 1-inch down from the upper right corner of the main-board to hold it down. The 60 series has a screw in this location.

RE: Machine turning self off and back on
Hi Sleeprider, could you please clarify which hole you're referring to (i.e. mark it on the photo) ?. I think I know which one you mean, but don't want to make a wrong assumption.

I appreciate the information and realize I probably just jostled the rubber gasket back into place during my assembly/disassembly getting at the motor/blower. Some of the plastic screw bosses on the lower side of my blower assembly were cracked, but I'm pretty sure that was self inflicted. I bought the CPAP used from Craigslist and while the unit didn't have many hours on it, it accumulated the smells of wet dog and cigarette smoke. Needless to say, I did a complete teardown (as carefully as I could) cleaning every surface with vinegar & water -- probably over-torqued the screws when I reassembled it a few years ago.

Thanks for sharing this information!

See the Service manual available from the forum. The screw location is shown in the attachment below. For odor, try Ozium. Spray cotton ball, place it near the inlet and let the machine run 20 minutes. It won't ever be there again. Also note there are 2 silicone seals in the humidifier dry box where the blower exhausts into the humidifier, and one silicone seal on the humidifier lid. These need replaced if you have smoke or other stubborn odor problems. They are available from Supplier #1.

This is what is on the back-side of that screw:

RE: Machine turning self off and back on
Thank you (belatedly) for the great information! Unfortunately in my case, I'm not sure it is the only problem. I did put a screw into the place you're showing and after disassembly/reassembly things seem to work OK for awhile, but sooner or later the cut-out problem shows up again. I do travel with my CPAP and that probably aggravates the situation.

Maybe in my previous attempts to fix the problem I caused some other issue -- will have a look at the service manual. I really love the auto unit and would like to keep using it. In the meantime I'm back to my old Bipap S/T machine.

It's great to hear new members are finding these results, and they continue to be useful. We rarely hear about this. Thanks back at-cha.
