Thanks Roger, I will try all of those suggestions. I bet many of those who
complain of poor cooling would be surprised at what a difference cleaning
this jet out will do. It is a difference of Night and Day.

Hello there, the vanagon has no filter for the propane that comes from the
tank.Seems like a good idea to me though. I would guess that corrosion
inside the tank can make it's way through the plumming , to the orifice.I
hear that gas valves that have been left open after the propane has been
expended, will allow moisture inside.Imagin leaving the valve open all
winter , or for years.Corrosion city.How are the burners for the stove? Are
they not affected? I know scuba tanks and other tanks like acetelene and
nitrogen need inspections at certin time intervals to check for corrosion.I
dont see why this corrosion cant work its way to that orifice.What I would
do,short of replacing the tank, is to blow out the lines real well,before
connecting the frig.In both directions.After all, this heaver than air
corrosion must work its way uphill and around several corners.I mean
compressed air from the gas station. Get a new gas valve,too. Put compressed
air to the gas fitting on the frig. Use your finger to push in the button
for the thermo coupeling while you do this(orifice removed!).You can even
remove the access port screw for gas pressure testing on the part of the
frig valve that the temp sensor attaches to. Blow all these out Then blow it
out in the other direction.Get everything cleaned out, and then hook the
frig back up.As for the orifice, that hole is smaller than can be imagined.
I think molecules can feel large , just looking at that hole.Oxidation can
restrict it.They say to use alcohol to clean it , and I believe this.Any
residue at all is not a good idea.What I did was to use a big syringe , the
type used to inject cows. Get it at Southern States or a farm supply store
on the internet.I filled the syringe with alcohol and attached the orifice
with a rubber hose and hose clamps. I shot up the orifice with enough
alcohol to make a party of 18 year olds happy.This pushes the cleaner
through the orifice , as opposed to just soaking it.I dont hear of other
listees having cronicly plugged orifices, so I would expect these
proceedures to work.
