I'm sure the link above explains it.
It does and the ammonia goes from liquid to gas and back.....but without actual compression.....and that's why it is still the refrigerant of choice in this kind of application.
VERY informative link. A link to a complete article is almost always better than just a few snipped pieces.
I found these parts good:
Running the refrigerator while driving eliminates the leveling issue altogether;
in most cases, there is enough rocking motion while traveling down the highway
to keep the contents flowing through the system without the fear of overheating.
Though a blocked percolator tube is but one cause of rendering a cooling unit faulty,
by far the largest cause of unit failure today is due to leaks in the tubing,
the best thing any RVer can do to protect the refrigerator is to always get it
as level as possible when it's in operation with the coach is sitting still,
Emphasis is mine.
I guess you have your answer. The Blockage is as hard as a weld and that is why Burping/Vibrating will NOT fix a blockage. In the OLD days(30 years ago) Dometic used to rebuild the blocked Cooling units. Rebuilders do that today. They have to cut out the upper tube assbly where the blockage is and weld a new tube in place, since you CANNOT remove that hard weld like blockage. Doug
