I replaced the burned out butterfly-style heating element of my Hot
Point gas dryer a couple months ago. It worked fine for a few weeks
but then my wife complained sometimes it wasn't heating the clothes,
but then she would start it again and it would work fine. I noticed
sometimes the heating element wouldn't get hot. The volt meter told
me it was always getting 120v when it was suppose to but it wasn't
heating, but it wasn't burned out either.

I thought maybe I stretched the clamp too much when I changed the
element so I took it apart and adjusted the clamp to make it squeeze
tighter. This worked for a few weeks. Last night it wouldn't heat
again. I tried turning it off and on a few times, but the igniter
wasn't heating up. Finally on the last try I saw a couple small
sparks near the igniter/clamp then the element heated up and the dryer
worked fine.

Should I buy a new clamp (maybe I over stretched it, doesn't look like
it though), new igniter (maybe I damaged it by touching the unpainted
portions) or should I use a dielectric grease between the clamp and
igniter to help conductivity?

Any help is appreciated.
