Where did you hear the loud pop come from?

If from the thermostat then there is a good chance it is bad. You can check it by connecting the Green and Red wires and the blower should turn on.

If it doesn't, you should check the fuse on the control PCB in the furnace/air handler. If it is blown you will need to call in a HVAC technician.
