[A/S] Fridge Exhaust

[<cacijohnson@xxxxxxxxxxxxxx>]

   Has anyone evr experienced problems with fridge propane exhaust fumes 
in their RV??  We are wondering if it is not the fridge but something 
else??   Here's what has been happening with us.

   We replaced our original 19 yr old a/c in mid Sept. Since then we 
have discovered that the odor we have been smelling is probably the new 
a/c sucking in fridge propane exhaust (where did that d come from in 
fridge? no d in the original word...).  Our carbon monoxide alarms go 
off.   Has anyone experienced this serious problem before?  
What we've ruled out so far:
1. Monoxide tester batteries replaced.
2. Monoxide tester has been tested.
3. Had our internal LP gas lines tested at RV place.  They found there 
is no leaking in the raw propane lines.
4. A/C installer says there would be no 'new' odors burning off in the 
new a/c and other RV repair people say concur.

Our thoughts:
Two major environmental changes for us since early Sept:
1. We are in 90's to 100+ temps day in, day out and so are running the 
a/c continuously with, of course, the trailer closed up.  We have NEVER 
been in this situation before.
2. Before Armstrong died it probably wasn't strong enough to pull in the 
exhaust fumes in that manner for the few days it ran more than it ever 
had before when it died at an SKP Pahrump, NV park.

   We figure the exhaust could be pulled in up thru the back fridge 
shaft - and probably other sorts of crannies...  Does that sound 
logical?  Even if we caulk all the many minute openings we will still 
have the back fridge shaft where the fumes can be brought in. 

Here's what we first are doing: buying the needed replacement electric 
thermostat on our 19 yr old fridge so we won't need to run the fridge on 
gas when we are hooked up to shore power.   We had opted not to replace 
the thermostat when it died this summer as everyone says it is an 
in-depth project since it means running the wire up through an opening 
and in thru a tiny hole in the fridge.  And we primarily boondock so the 
120 electric is seldom used.  We do not want to become a death 
statistic.   So it seems it has become VERY important to pull out that 
fridge and do the in-depth replacement we previously avoided.  
   All insights are welcomed.
