does the dryer heat initially when you first turn on the dryer Or no heat at all?

the first thing i would check is tthe thermal fuse thats located on the back of the unit. test it with a multimeter and see if it has continuity, if it doesnt then replace that and your operating thermostat. the check to be sure you venting to the outside of your house is not clogged
