Hi all,
I am having trouble with the temperature regulation of the GC oven on our
EA (Carlo Erba NC2500). The temperature is maintained 6 degrees higher
than the setpoint, regardless of the temperature you set it at, and never
reaches the set temperature. You can see the LED cycling as it maintains
the GC at the wrong temperature--consequently it never goes into the
"ready" mode. There is the ETPL 430 board which regulates the GC oven
temperature and maybe the problem is there, but I don't have circuit
diagrams or any other info about that board. There are 2 pots on this
board, maybe they need to be readjusted? Does anyone know what the
problem is and how to fix it?
thanks in advance,
Cyndi
