Dave,
Several of us have had problems with the LP systems. The factory reset the pressure on mine, said it was 9 and it should be 11? I'm still having problems though. Mine will switch over and then as the level of the tank falls (in a few days) the furnace will quit igniting until I switch to the other side tank. The problem always occurs when it's set on the passenger side tank. Still have not gotten to the root of the problem but still working on it.
Steve,
Thanks for the pointers! I just happen to have an odd ball sock that lost it's mate. I was going to throw it away but will keep it so I can sleep.
Dennis,
Yes you can still see the red/green indicator.
