I suggest that you wait on taking your fridge in for repair. I think
that the difference in performance may be due to the pressure of the
propane. The tank has a 2-stage regulator that sets the pressure level.
The fridges that I know of that cool really well have both had this
regulator changed to the new model, as the old model is no longer made.
Is yours still the original square shaped Marshall #260? The new type is
rounded and is a Marshall #290. In both cases these regulators are
adjustable. It is possible that the fridges that cool best have the
highest amount of propane supplied to the fridge burner. The regulators
may be wearing somehow and lowering their output pressure. We need to
find the answer to this question as taking the fridge in for repair will
gain us nothing if the problem is actually tank related. Does anyone
know how I can measure the pressure of my regulators? I have a Westy
with the original regulator that does not cool nearly as well as my
Camper with the new type of regulator. I would like to compare the
pressures to see if this is the reason.
