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.

It's not clear that you machine is doing recover or not! If the machine is doing recover theh follow the bellow steps.This is a common problem of Robinair 34700Z / 347002k

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.

Disconnected Air Purge lines. It was under high pressure (careful).

Robinair Cool... | Answered on Jul 12, 2016


This is a common problem of Robinair 34700Z / 347002K & 347112K series machine. So don't worry just do the following, with POWER SWITCH OFF: - 1# Open front panel cover and verify the ISV tank is not overfilled. If full, carefully remove refrigerant manually from ISV tank by pressing tank valve. 2# verify if there is high pressure in the ISV tank. Purge excess air from the tank manually. (Open air purge hose from the ISV tank, then carefully press tank valve as needed to blow out excess pressure from the ISV tank)

After doing all above stapes and your problem still exist then replace air purge solenoid (Air purge solenoid located near the ISV tank and fixed with automatic air purge device). Hope this will solve your problem, if so please vote for it for farther help! Good luck
