Hi @deniseg480
Check that you haven't jammed any wires against the frame of the dryer, connecting the supply voltage directly to earth and tripping the breaker.
Looking at the wiring diagram on p.24 of the [document|35357|tech sheet], when the motor gets up to speed the centrifugal switch in the motor completes the power path for the heater circuit.
If you have a DMM (digtial multimeter), unplug the dryer from the power and then using the Ohmmeter function in the meter, connect the meter to one side of the thermal fuse or heater and the frame of the dryer (bright shiny metal point) and check if there's any resistance showing on meter. It should ''not'' indicate 0.00 Ohms i.e. a short circuit. Also make sure that the heater element itself is not short circuit as well.
Just what I'd try
