Our member Rickst29 got a copy of the service manual for the Norcold N300 refrig, which is used in TMs beyond 2005 or so (don't rely on that date). At any rate, it contains a lot of info not found in the owners manual, and he asked me to upload it here. Thanks!
This being a service manual, it gets into a lot of information about the propane part of the refrigerator's cooling mechanism. Rick remind us that "If you don't KNOW propane, don't poke at the propane system -- you might blow up your TM, your garage, your house, and your wife and kids too!"
The thread that resulted in the need for this manual is here
