Product review (5 stars): just the part I needed!
This is the same item I have replaced a few times before in my gas dryer.  It tends to burn out when the dryer overheats due  to blockage in the vent.  I try to avoid it by taking off the back of the dryer and removing the vent while also cleaning the main exhaust vent at least every 2 years, necessary with 8 kids.  Otherwise you will need this and it handy to have a spare!
