The Bryant furnace I have is model number 376cav036075 and the blower come on but the inducer and the ignition switch don't seem to come on so the furnace in sending out cold air.. What could be the p roblem

First the inducer motor has to start before the igniter can fire, so you need to test inducer to see if there is power available at the time of start up,, whie you are at it check and see if there is a fuse (automotive type) in the control board/circuit board,, is it good>
