Robinair 34700 recovery problem
My ser number is 22447. Date Code 0298. In recovery mode the machine will only run for several seconds, and then it shuts off for high pressure. I have verified that the recovery solenoid is opening. The compressor is running. The machine high and low guages show that the vehicle has 75psi. We connected an auxillary guage to the port just before the filter drier and it shows shows 35 psi when the machine is trying to recover.

It sound like one of the pressure trunsducer is not working or disconnected from the manifold assy.or from ISV tank.Please check Low,High and ISV tank pressure transducer
Yes,you are right! There was blockage somewhere in the manifold assy.that the recycle or vacuum pull cleared! You can continue to use the machine. but remeber every time when you press recover, do not skip "Clearing in pogress" mode. because during self clearing machine test it self to work normal.
