when did you get the LP
some places sell butane in the summer instead of propane, both are LP
butane will not function properly at 10 degrees, it won't vaporize fast enough to produce a steady large demand volume
could also be moisture icing up in the regulator
yes..try another tank of Propane

NOBODY sells Butane for DOT LP tanks in the USA anymore. You can get Butane in Mexico. IF you light the stove burners and leave them ON, when the furnace lights, if the stove burners stay on at the same flame level, then
1. Possible Butane is ruled out
2. No Excess flow problem.
You CAN light the Water heater. You do NOT have to have water in it to run it for a few minutes on LP to test your LP system.
A BAD Hi limit switch on the furnace will NOT reset before you restart and the furnace fires every time you attempt to get it running and stay running. It takes time for the Hi limit to reset if it trips.
I would suspect a kinked LP line or your battery/Converter is not above 12.5 volts and the Fan is not running at the correct RPM to keep the sail switch closed. Long shot is a Bad Ignition module. Doug
