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.

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.

Phone the agents for the answer.

Please check 1# Both service hoses (Red and Blue) fittings to the machine for damage of any "O" ring. 2# Check small compression fitting hoses back side of both gauges (Low and High) for any lose. 3# Check Vacuum check valve and Vacuum solenoid (see attach picture for location of Vacuum check valve and Vacuum solenoid) for any blockage or damage of check valve gasket and solenoid plunger.
