I am experience a problem with my kiln, the controller is displaying a
decrease in temperature as the actual measured temperature rises. My
technician only knows old school. Any suggestions? Is it the
thermocouple or the board.
Thanks for the help.

Here's a thread from the archives on Gare kiln controllers that might be of
help:

Have you inspected the thermocouples and their leads?

Reversing the thermocouple wires will cause the temperature
to go down instead of up. Did you change the thermocouple
recently?
The wire connections are at the thermocouple and at the back
of the controller circuit board.

Hi
This could be very simple. If you have changed anything recently it could be
as easy as having the 'positive and negative' wires leading to the thermocouple
in reverse position.
I know when I have inadvertently switched them in the past, (or when the wires were so charred
and old that it was difficult to see the wire casing color) the temperature would head the wrong
direction when heat was applied. Simply switch the wires or the thermocouple orientation.
If this is something that happened on its own, I'm afraid you have electronic issues.
