<p style=”text-align: left;”>Are you sure that you have propane? That’s what the furnace does if there is no propane, or not enough pressure in the line.</p>

first thing I checked, removed cover outside to check for insect junk but couldn’t see that far in but there is a switch going to the control board and turned off then on and it lit and is now running. Hmmm

well i got out the volt meter and checked the wire at the sail switch, and it started at 11 volts and started to drop as the furnace ran to under 11 volts. Doing some research the furnace needs to see at least 11 volts to run properly.

I had the battery disconnect switch turned off so the charger couldn’t replenish the battery as it was being used, hence the loss of battery power which caused the furnace to not run again when needed. battery disconnect turned on now it runs as advertised and not problem.

operator error!
