Happy Birthday Carol,
Now to the question. Is this a new thing happening? My question is
this--is the heat radiating from the kiln to the fan box or is the fan
pulling excessively hot air from the kiln? Vent systems mix room air
with the vented kiln gasses to help dilute the heat before it gets to
the fan. You checked your plenum lately?
If its radiation, just try a heat shield that gives a couple of inches
of air space between the fan box and the shield. make it metal.
kisses,
Taylor, in Rockport TX

The downdraft vent is designed to pull only a small amount
of air from the kiln. A vent will pull too much hot air if
there are too many exit holes in the kiln.

Getting' pretty gal-dern hot will shorten the life of the motor and probabl=
y
over heat it causing it to fail during a firing - of course.
Trying to recall your kiln set-up - seem to recall kilns back in a corner -
a location that'll trap heat in that area.
Can you set up a portable fan to blow over the kiln right onto the vent fan=
?
I have a commercial fan like this:
>
This fan moves lots of air.
I use it during warmer weather to to blow on my kiln to keep the controller
within it's operating temperature range.
Maybe the standing fan on this Amazon page would work for your situation.

Hi Carol,
I am heading towards Md. this weekend to see my mother. How's the =3D
weather up there?
I had a heat problem in the kiln room in Montana. I used some used metal =
=3D
litho plates (oxymoron) hung by wire from the ceiling.These were =3D
protecting the electric box for the Honeywell purple peepers =3D
(ultraviolet heat sensors. They would overheat and shut the kilns off. =3D
The metal plates deflected the heat. They too got warm , but nothing too =
=3D
serious.

the electric boxes controlled the sparkplug ignition and the pilots with =
=3D
the purple peepers. In 1980 it was "state-of-the-art according to the =3D
engineers for the University. Anyway, the radiant heat was the problem. =
=3D
Behind the kilns and on the opposite wall were louvered vents near the =3D
floor and also about 6' high. There was also a ceiling vet about 3' x =3D
4'. The room was about 30 x 30 ft." The metal sheets, former lithography =
=3D
plates were behind the kilns and protected the electric controls for the =
=3D
gas safety system. The burners were back there too.=3D20

I had a heat problem in the kiln room in Montana. I used
some used metal litho plates (oxymoron) hung by wire from
the ceiling.
--------------
In Hawaii I once built an 8' x 8' room. It had a pyramid
roof and glass skylights. I bought a pile of printer's
plates for $5.00 from the Hawaii Tribune Herald and sheathed
the entire building with them. Even in the heaviest
downpours, not one drop of water leaked in.
