Dryer not heating

My dryer is functioning but not heating-the present coil glows for 15/20 second and go off after that- i hv ordered the new coil your part # 3094251
which i believe come as a pair- to replace this do I need to remove the whole burner section or only the section that has this coil- of course I will unplug andshutoff the gas input before starting-pl adv.

VBN,

This is a simple repair. There is a metal cover on top of the coils being held with two screws. Remove the cover, then pull the coils off one at a time and replace with new ones, put the cover back, make sure the holes in the cover line up with the coils and you’re done. Finish putting the dryer back together and try it. These instructions might be useful.
