Hi!

If you touch the active part of an igniter while installing it, you can
shorten its life.

If this is anything like my Whirlpool dryer...these are not ignitors. They
are coils that operate a gas valve solenoid. The ignition is a tube shaped
device that glows yellow before the gas eventually lights up.

The original poster does need to provide more information, such as the
results of an ohmmeter test on the "bad" coil. I can't imagine what would be
opening up the coils, as they are usually pretty well protected and sturdy.
