I have a kenmore 70 series dryer that will spin but won't heat! I changed the thermo fuses, but still have the same problem - no heat!

are you getting power down to the heater?why did you change all those other parts?you need to unplug the dryer,with a meter read out all the parts you changed out again but first make sure you have 240 volts coming to the machine,you can check it at the cord in the back,touch the white to the red,you should have 110 volts or 120,then go from the white to the black and you should have the same thing,if not the problem is in the house,if it's correct make sure you have power coming down to the heater,you could have a bad timer or a burnt wire,when you check the other parts unplug the dryer and whatever part you check at least one wire has to be removed,do this and you'll find your problem,if you did this first you wouldn't of bought all those parts.let me know what you find
