Furnace burner intermittent

[Cooter]

I have a 2017 379RD. When I turned on the furnace the blower came on then the burner ignited. It ran a few seconds then the burner quit, the burner ignited again for a few seconds then quit. After the third time of doing this the blower quit. I have increased the thermostat setting, I have plenty of propane. Anyone experience this?

If the furnace has worked fine in the past, you might have opened the valves on the propane tanks too fast, which would set the excess flow valves in the pigtails. To fix this, close the valves, remove the pigtails from the tanks, then put them back on, and then open the valves very slowly. Then give your furnace another try. There are other things that can cause the furnace to do this, such as a bad flame sensor.

I ran mime out of propane and it did that. I turned the thermostat of for 10 seconds and back on. It ran fine after that
