Welcome to the forums.

There is no reset button on gas furnaces...... only oil furnaces.

You turn the power off for 30 seconds to the furnace and then back on. That resets the control board.
Put your thermostat in FAN ON mode and see if the blower runs then. If it does.... there would likely be a problem on the control board. If it doesn't work it's either a control board or motor problem. Typically when the blower is dead it's a motor problem. You could open the blower service door and see if the blower wheel spins freely.
