Did you actually measure the propane system pressure coming from the
regulator? Until you do so you are just messing around. Set the pressure
to between 10.5 and 11" of water. Make sure the system pressure is good
even when the stove burners are on. Once the pressure is known to be
right you can proceed to fixing the fridge if needed.
