When you say "nothing" do you really mean nothing or no heat?
If there's no fan despite a "click" from the thermostat then there's a good chance it's the thermostat itself (assuming the furnace fuse is good). That's how mine failed. It would intermittently not call for heat despite the "click" until one day it stopped working completely.
Depending on the type of thermostat, you may be able to jump across the terminals to see if the furnace runs.
If other things are happening, like flame but no fan or fan but no flame then further diagnosis is required.
