Maytag Dryer coils going bad

I have replaced the coils in a Maytag dryer twice. Each time, one of the
pair of coils is burned out (I presume). What would be damaging a coil so
quickly and why?

The syptom is that the gas will not ignite. When I replace the coil, the
gas ignities for a while, but shortly thereafter, it fails to ignite and
will not ignite again. I noticed that the damaged coil is very warm when I
remove it. The other parts adjacent to it, and the other coil are cool.

Can anyone help?

thanks
