My SV34 Magnitude Furnace Won't Ignite

[rknapman]

My 2023 Magnitude SV34 Furnace on ignite. Fan comes on but no heat. I just filled the empty propane tank and lit the cook stove to purge the gas line. The water heater also ignites fine. I assume the access point to my furnace is next to the access to the water heater on the outside of coach. Any ideas? I'm hundreds of miles from nearest warranty repair center.
