These are all valid suggestions for troubleshooting, but I'm still
puzzled why the blower comes on if there is no flame?

I thought maybe the OP was referring to the draft inducer rather than the
main blower. Or maybe the control is in a lockout mode which runs the main
blower.

I think it is the main blower that is running. *What might cause the
controller to go into lockout mode?

I thought lockout mode shuts down everything, including the blower,
and must be reset manually.
