Chuck,

BTDT.  You'll need a new regulator.  I had this problem as well as a bad
autostop filler valve recently.  Good news is that they are fairly cheap.
The only messy part is that they don't make the stock regualtor anymore.
I was lucky enough to find a dusty stock unit in a trailer park near my
place recently, but you'll probably need to find a Marshall Brass brand
regulator at your local RV parts store and 'massage' the 2 gas lines since
the newer ones are longer than stock.  Just take  your time and try not to
pinch the lines in one spot.

I don't have a thorough understanding of the regulator, but it just steps
down the tank pressure to a pressure that is copasetic for the fridge and
stove.

HTH,

John Haddad
