RV cooling units CANNOT be refilled. They must be rebuilt and then filled with specialized equipment. IF the Ammonia has not leaked out and the Cooling Unit is bad, that means it is BLOCKED. Rebuilders cut out the Blocked tubing and weld new tubing in place and then charge the cooling unit. Doing the work yourself, rebuilds are a great way to fix your RV refer. Not hard to do, and they come with directions. Doug
They can be refilled. Check out the place in Kentucky that does the training. They sell equipment and provide training to do it.
