Gas dryer not heating up. Asking for input. thanks.

I have GE Profile model DPSB620GCWW gas dryer.  The dryer will operate as usual, but it does not heat up the clothes.
What could be wrong?  We would like to fix the problem ourselves. 
Thank you in advance for any input.

• 用电表查一下后面的几个保险丝，把坏的换掉。抄一下型号，在amazon or eBay 上买。 -天涯子- ♂ (24 bytes) () 09/13/2013 postreply 20:15:47
