Product review (5 stars): Simple and Saved me Money
Bought this for my Samsung dryer. The TO code indicated a thermistor issue.  YouTube videos showed me how to take apart the dryer.  The new thermistor was popped in.  Took 30 min to open - 20 min to close up.  Dryer works great (it has been two months).  Saved me hundreds $ in a repair.
Bonus: opening the dryer also allowed me to vacuum out tons of lint.
