Did you get a limit error on board?
If furnace shut down because of dirty filter,you may have two limits on back of blower housing that trip and a main limit in furnace vestibule.Most of these are auto reset and will rest themselves once cooled down,Some have a small button in center that pushes in to reset.When you get home,Lets turn power off and back on to furnace .Then call for heat and see if furnace will light or what error code we get by light on board.
I will help you diagnose the code.Just let me know what lights do for example 3 and 1 indicates an open limit.
