[/url] That setting a high temperature worked.
If I set it for 200C, the flaps did close (squealing the whole while) it will reach T and hold it and I can step down in 25C increments and flappers open and it drops down and holds temperature. Got it all the way down to 50 then set at regular T of 40C. I'm now doing a run and it seems to be working.
I suspect the flapper motor is limping and will soon fail. My question is whether I will need to vent to get at the flapper motor to put in a replacement.
Because:
1) f I shut down the 5890 I must suppose capillary wiil be shut off, or not constant, or worse uncontrolled flow will be too high?
2) I'm not sure which side of the GC the power and control leads are on. I assume it would be on the right as looking at the 5890, same side as the power switch.
3) I'm not sure how much I need to maneuver the 5890 to get at the flapper motor.
