pyrometer event has me stumped

Hi Clayart,

Hoping for some explanation of this:

Last night I noticed that the computer machine went to "FAIL"
when I dialed to the bottom pyro, and recalled this had happened
before recently.

Now when the kiln was at low temperatures or room temperature,
this didn't happen, so I didn't notice it between firings.

This morning I figured I would have to put the #3 level pyro in the
#4 peep, and moved the cinder block above which the #4 pyro had
been jammed, and suddenly it started to register temp and quickly
gained temp on the readout until it looked right, a few minutes.

So, how was the cinder block impeding the pyro from operating?
Any ideas?

Thanks,

Eleanora

One of the wires in the thermocouple block may be loose. Sometimes a
thermocouple screw is tight, yet the connection is still loose, because
the wire under the screw is broken.

Have you checked for loose or corroded connections with the wires?
