I have seen several posts on cooling issues. I have a ZWO ASI1600MC-Cool camera.
I recently updated to SGP 3.0.1.0. I have also update the ZWO ASCOM driver V1.0.3.15.
My camera (ZWO) does not appear to be cooling. Although SGP says it is active.
Under the Camera selection, I select ASI Camera (1).
It says it is cooling down (cool down running) and the cooling status bar is advancing but it
is not getting any cooler.
This work with the earlier version of SGP and the ZWO ASCOM Driver.
I have seen other post on cooling issues. Has anyone had similar issues?
DO I need to back off SGP and ZWO ASCOM drivers versions?
Just to be clear you updated the ASCOM driver as well as the native driver inside of SGP? I haven’t tested against 1.0.3.15 but I can do some testing this evening to see if it causes issues.
May be worth checking to make sure that the power connection is good. The ASI1600 will appear to work just fine through USB power, except for the TEC.
Yes I updated (purchased) the new SGPro 3.0.1.0 and updated the ZWO ASCOM driver
1.0.3.15 at the same time. I use the ASI Camera (1) selection (& not the ZWO camera).
I have check the cooling 12 v connection (voltage test & reconnected the power connection).
I observed the fan running.
For the camera control connection, I use a USB2.0 cable as I have seen issues with connection with their USB 3.0 cable (not finding the camera). With the USB 2.0 cable I am able to connect & control the camera.
Except for the cooling operation which appears to be running but does not really cool the camera. It worked with older version of SGP & ZWO ASCOM driver.
I thought I had the same issue, with SGP showing cooling, but the temperature wasn’t dropping. After talking with ZWO customer service, it turned out to be a bad TEC power connection within the camera. It’s a known issue with the ASI1600 both STD and pro. They’ve documented and sent me a simple procedure that fixed mine. I’ve put it on Dropbox. ZWO customer service was excellent.
I have the ASI071MC Pro. I experienced cooler problems when using SGPro and the same setup and drivers as Brent is reporting. I was seeing apparent cooling activity but crazy oscillations in reported temperature (at one point it was showing 83 degrees with the cooler running at 100%). My local dealer (Tring Astronomy Centre) checked it out using Sharpcap 3 where it also failed to cool. The camera was immediately replaced and the new one works fine with SGPro (and with Sharpcap 3). It seems Sharpcap 3 (which is free) is a good ‘tester’ for this camera.
Hi @Buggs
Interesting, I reported the exact same issue with my ASI071 Pro a few days ago. I have not gotten any response back from ZWO. I’m seeing temperature all over the place. from over 100 Degree C on second and the next it might say 45 degrees C. The cooling power is saying 100% but it is not cooling. I did reach out to the vendor where I purchased the camera and they are looking into the issue for me. Nice to see other folks having the same issue, I was swapping USB cables both 2.0 and 3.0 as well as power supplies but was getting the same results in both SGP and SharpCap. Thanks for posting that help to confirm the issue I was seeing.
So I implemented the fix from the post from Phil (pmont1, above). I was I mentioned above
above when I started this topic, I was seeing almost exactly what has been described in the
other posts of this thread.
I have re-tested and at least from SGP control panel (camera) it appears to be working.
Although I am not sure as I cannot physically feel if the sensor is cold. I will try to determine
if it is actually working.
Phil mentioned this was a common problem on ZWO where the TEC connector pins do not
make a solid connection leaving the TEC not connected.
If anyone else would like to try the fix and how there camera responded, I would appreciate it.
Thanks Phil for sharing the information.
Hi @bjaffa
Sorry, my Camera is still under warranty and unless either ZWO or my dealer approves me doing the fix I’m going to pass for now. I’m very surprised when I looked over the directions that was posted and noticed the type of connector they selected. Doesn’t seem to be a very robust connector considering the environment these cameras will be exposed to year after year. Anyway I hope if I get mine replaced with a new one and the connector is of better quality, if not I would expect the same issue will occur over time. I hope I’m wrong.
