Product review (5 stars): Fixed our drier problem.
Fixed our drier problem. This is one of the more common causes of the drier's gas burner not coming on (do a google search and you'll see).  Be sure to also get the troubleshooting document that is taped to the inside of the lower cover of the drier (why they don't have it in the manual I have no idea...I didn't discover it till I found out about it in a google search).  This was a 5 minute install not including vacuuming up the lint in the lower areas of the drier.
