Make sure your not out of propane. May need to switch to other tank. Try starting stovetop to ensure gas is flowing.

Does the burner ignite at all or just the fan run and then stop? If just the fan it it likely the sail switch in the furnace.

I can’t find the furnace to check the sail switch

If it does not have an external access door find the exhaust and it will be on the other side of the wall. Likely in the basement/storage area behind the wall.

The only exhaust I can find is at the water heater when the heat is on it comes out of the same exhaust as the water heater if I cycle the heat it does come on but not always got to find the sail switch to see if it could be blocked by some critters
