Did you suddenly wake up to no heat this morning?
It could be a frozen regulator. Try "slowly" pouring tap hot water on the regulator under the propane tank lid on the regulator or the regulator attached to the side of your house.
The inside of a regulator has an or***ce that can get restricted from moisture suddenly freezing and restricting flow. Heating up the regulator will thaw the restriction and get it flowing again.
You may have to turn the power off and on again to reset the furnace board and make it try to operate after locking out.
The other thing to check is your propane levels. If you are below 10% it may struggle to work properly. Propane "boils" at -44β° as we get close to that temperature low volume of propane will "boil" less and struggle to create enough pressure. Check your gauges to verify your levels.
