Suburban SF-35 Propane Furnace won't ignite

I'm stumped. I live full-time in Newmar 5th wheel. Pretty standard Suburban SF-35 propane furnace with (2) 30# propane bottles with auto change over regulator. I ran completely out of propane. Obviously no propane no heat. I filled bottles as usual, opened valve slowly and the furnace will now not light. I have gas at stove and at the hot water tank with no problems.
I have pulled the fuse and replaced it with one the works. I have switched tanks and verified it's not a tank issue. When I set the thermostat to "furnace" position and raise the temperature setting to call for heat I can hear a relay "click" sound and that is all. This furnace has worked well and has been run out of propane before. I removed the exterior cover and there is a 5 amp fuse that appears ok. I have 12.4 volts at the battery. Ideas??? Thanks

Turn on all the stove burners to be sure the system is purged and try again.

It's well purged at this point. It happened about a week ago. No problems with propane at stove or hot water tank. We are in Sarasota
Florida. Staying warm with electric heat!

You said you have 12.4 volts at the battery have you checked the power at the furnace control board? Disconnect power to furnace for a few moments then reconnect may reset the control board.
