This problem first popped up last Saturday night. I couldn't get the CCD to cool below 7c then. I did some powerdowns and it began working. Cooled to -5 as I normally have it set. Today I'm running it on the bench to debug this issue. I'm using a regulated powersupply at 13.8v to power CCD. I've used several different USB cables and 2 different power cables. There is no problem connecting to the camera and the cooling power percentage changes when setpoint is changed. All seems to be working, the camera takes images and downloads them. I've used APT and SGP and run the cooler today and from the ASCOM driver. Trace on is ON and there is no errors in log, but that is avail if needed. The only issue is that is can't seem to get full cooling. Last weekend the ambient was about 18c and the lowest it would go was about 7c. Indoors today it is about 23c and the lowest it will report CCD temp is 16.6c.
Is this cooler failing?
