I'm currently trying to revive an Agilent GCMS (5973/6890) and I encountered some issues.
I changed the brand new heater/sensor assembly for the ion source as I noticed one wire was broken when I tried to clean the ion source. After I turned on the MSD as well as the GC, everything looks ok except the MS Quad temperature, it always showed around 320 to 360, and never went down to the setpoint 150.
Is this caused by a defective Mass filter heater assembly (G1099-60172)? I checked the manual, but it seems this issue wasn't mentioned.
In addition, I am able to run a sample if I hit override button to ignore the MS Quad temperature setpoint, but it will show no GC and MS signal collected in the logbook, and there's no TIC at all. I'm not sure if it is the defective Mass filter heater assembly causing the issue.
Does any one have the similar experience? Any comment would be appreciated.
