My Kenmore 80 series gas dryer (m/n 110.72812101) began to stop drying completely about a month ago. After reviewing some posts on this forum I replaced the coils and the problem was resolved. After only a month the same problem is back. I don't have an multi meter to test the coils and was wondering if anyone had any insight on whether this could be the same problem as before, or if I missed something and just got lucky temporarily bu replacing the coils.
