Hello, Rusty. I am new to this R.V. thing...so new that I haven't purchased my R.V. yet. After a lot of looking around, I've decided to go with the Toyota model. but that's another story. As for your ammonia refrigerator, try this: disconnect the refrigerator, remove it, and turn it upside down. Let it set for 24 hrs., then re-install it. I've done this to a friends R.V. refer and it worked great. (I used to do refrigeration work with freon, but I read about this trick in an ammonia system troubleshooting guide and it really works).
