Product review (5 stars): Check your breaker switch first
This did not work for me, but I don't believe it is because of the product. Some dryers can run even when your breaker switch is partially tripped, so I believe this is what happened in my case. If your dryer runs but does not heat up, first check that your breaker in the circuit box is not partially tripped before you start trying to fix it. I replaced the element, thermostat, thermistor, and everything else in my Samsung dryer and still couldn't get it to heat. I got rid of the dryer and bought a new one, only to have it do the same thing - no heat. I then started researching on line and found that some dryers will still run with a breaker that is partially tripped, they just will not heat up because they need 220 volts for the heating element which the element cannot get because the breaker is partially tripped. I learned that hard way. I hope this helps someone else.
