Hello guys,

Today we stumbled upon a very strange problem with our CP9001. The temperature settings for the GC were 70 degrees for the oven, 250 for the injector and 250 for the detector.

The oven won't reach the 70 degrees however, it stays stuck on 96/95 degrees. But when I measure the temperature of the oven it is 29/30 degrees. So somehow the displayed temperature on the GC is way too high. Also the temperature isn't stable. The detector and injector temperature vary between 247 and 253 (normally it stays perfectly at 250).

Also the temperature setting for the Aux1 and Aux 2 is 0, but the actual temperature is 44 (normally it also says 0).

I think that the GC somehow displays all the temperatures too high (higher than reality) and I have no idea how this is possible.

I recently uninstalled the FID detector and installed a FPD detector (but yesterday the temperature was still OK with the FPD detector and it happened overnight).

Any help will be appreciated.
