Courtney,

The flame switch adjustment is most likely the
reason .
You shorten the after-run by turning the screw
counter-clockwise.

It may be that the flame switch quartz rod is
stuck or broken. If adjusting doesn't work,
whacking it may break the quartz rod which
expands with heat to turn off the glow plug, and
contracts after cooling down to shut off the
blower.

The switch could be worn out, or need cleaning,
etc.
I have spare flame switches for sale if needed.

O yeah, I have been working on gas heaters for 20
years. I have a lot of parts, and if you need to
, you can send the heater here for service.

I probably should mention this on the list more
often like a used to.  I've been on this list for
ten years and I guess I have assumed everyone
knows I work on gas heaters.
