Hello all,
I have a 7100 that will not ventilate when switching from bag to vent mode. I have checked the microswitch on the lever and the GUI does show indicate which mode its in. I can here the vent engine actuating but I get no movement from the bellows and no movement of air across the flow sensors, thus I get no waveform on the GUI. I have done all leak tests in service mode and in normal operation mode, with no leaks.
I have done all calibrations and diagnostic checks in service mode with no problems. The s/w is 1.3.
Any help insight would be much appreciated.
Thank you

HI Troubleshooter,
Thank you, I did confirm drive gas is set to O2 and I have 52psi at the wall. Also have confirmed pneumatic connections with no leaks present and have torn the breathing assembly apart a few times just to make sure there were no leaks there as well.

Remove the drive gas check valve it gets stuck some times. Reseat it. Did you do a 2 yr pm kit replacement recently?
