Good stuff here. Now I have a q related to this. How long can one run the
fridge on high with a full tank before they run out? Hours? Days? I havent
hooked up my propane yet and have been surviving on battery power. The
batteries dont seem to last very long; only about 8 hours before they get
low without the engine running. I would really like it to last longer. I
feel that my mechanical R12 fridge would last longer than the Dometic unit
on the same batteries. Any ideas?

>>Hi Jason,
>>
>>Here is a reprint on how I fixed my fridge in 2000. The blowing out part
>>is in bold print at the end.
>>
>>I bought my 85 Westy new in 85. The fridge worked but never
>>got very cold and kept blowing out while driving. I thought
>>that this was as it should be. Since joining the Vannagon
>>list I found all kinds of material in the archives. Last
>>summer I finally slid the fridge out. The fan was resting
>>against a pipe and couldn't turn. I'm surprised it had not
>>ceased as the electrical supply to it was ok. After
>>cleaning the combustion chamber, orifice and sealing
>>everything off properly it now works great. I even figured
>>out the theory of the lighting procedure so I have no more
>>problems with that. I then went on a 2 week trip and left
>>the fridge on all the time. Not once did it blow out and it
>>actually made ice in the little tray.
>>Here is what I did:
>>I opened the combustion chamber and removed all the dust.
>>There was quite a bit in there. I also removed the gas
>>orifice and soaked it in alcohol overnight, then let it dry
>>out. Do not poke any needles or wires through the orifice
>>as you will ruin it (It is made out of a gemstone and is
>>very brittle). When putting back together make sure to seal
>>it again airtight as any leak will tend to blow out your
>>flame. Get some high temperature gasket sealer if you
>>ruined the original gasket when opening the box. As for the
>>fan not running, check the small temperature switch fastened
>>to the fins of the heat exchanger near the top. Make sure
>>it makes good contact. As the fridge starts to operate the
>>fins get hot which closes the switch and turns on the fan.
>>I tested mine while I had the fridge out by making the
>>electrical connections and then blowing hot air from a
>>heatgun onto the switch (A hair drier on high should work
>>too). If it works your ok, If not bypass the temp switch to
>>check if the switch is faulty. Before putting the fridge
>>back in click the sparker and Check if you can see a spark
>>in the combustion chamber, make sure you do otherwise you
>>won't be able to light the fridge. When sliding the fridge
>>back in, be very careful with the spark wire as it is at the
>>very bottom edge of the fridge and you can easily shear it
>>off from the sparker (I did) and then try to fix it or try
>>to find another one which isn't easy. When you have the
>>fridge in, connect the propane and the electricals but leave
>>the outside vent cap off until you get the fridge to work on
>>gas. Bleed the air out of the line by lighting the stove
>>for a bit and pushing in the lighting knob for the fridge
>>for a while. Blow in air into the combustion chamber from
>>outside by blowing into the tube which is off the center.
>>The center tube is the exhaust vent. Now light the fridge
>>and let it run. Listen to the fan come on. Feel the heat
>>of the fins by reaching in the through the hole on the left
>>of the cabinet, when the grille is still off. Once your
>>fridge is working as it should, carefully put the outside
>>vent assembly together. It is critical you put it together
>>properly and add some sealer on the rubber gaskets (I used
>>transparent silicone sealer). The intake air must come in
>>only through the off centre hole and not from the sides.
>>You don't want any wind-pressure to get in as you are
>>driving and blow out the flame.
>>
>>Anyway good luck
