Subject: Re: Fridge Orfice Keeps Getting Blocked Any Suggestions?
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.
