Robinair Cool-Tech 34700z sending refrigerant to oil recovery container when charging system.

You confirm it by how it functions, if it sticks in a mechanical way there is no electrical testing that would be valid. I would just replace both solenoids.

This is a common problem of Model: 34788, 34788-I, 34988, AC34788, GE48800 etc. You need to replace air purge solenoid (Air purge solenoid located on top of the ISV tank, if you open front panel cover then you can see it on top of the tank). After doing above stapes and your problem still exist then you have to replace PCB relay board. Hope this will solve your problem, if so please vote for it for farther help! Good luck

Machine won't recover, it gets stuck on "clearing in progress" Also won't vacuum, it says that "pressure exist press any key to continue" Your help would be greatly appreciated

I had a similar problem with a Robinair 17800b. The machine got stuck in Clr or (Clearing) while changing from R-12 to R-134a. If the tank (R-12 or R134a) does not have at least 10 pounds of refrigerant in the tank before you change to another refrigerant, the machine will stay in the clearing process. I called tech support and they walked me through a process that resets the machine. The reset involves entering a code while in r-12 mode, then removing all hoses and switching the switch to R-134a mode and entering another code. The call to the tech line took about 5 mins. The number I called 1-800-822-5561.

Robinair 34788 will not charge properly

I would be very careful releasing refrigerant from the liquid side of the tank as suggested earlier. Knowingly releasing R134 into the atmosphere carries very large fines if you get caught and is very environmentally irresponsible.
