My first tests were with external temp 5-10 C° and sensor temp -10 C° without problems.
Yesterday, with an external temp about 15C° (sensor start about 18C°), when the sensor arrived al -10C° I noted this strange grid on the right side of it. I lowered the temperature slowly: about 15 minutes from +18C°to -10C° (first raw image).
When I returned at 0/-5 C° the grid disappeared (second).
.... but appear again (and terrible) when I lowered the camera again at lower temp (-20C°)! (third image)
The grid on the sensor appared from -8 C as in my first photo.
The camera has only two months and I paid it 1.700 euros (in Italy)! What should I do? I see that cooler's problems are very frequent with this camera that is very expensive.
I think that ZWO should quickly solve this serious problems and quickly replace defective ones. Because è new camera with this problem is defective, I think. I hope you wont ask my, to open it and try to solve the problem.
This is zwo support' s answer. Now a custom for these, that seem, very common problems (in mine the grid it very strange)
Thanks for your email.
I am sorry for this problem.
You can follow this quick guide and redry the camera.

Do you suggest me to try solving the problem opening the camera? And If I worsted the problem loosing the warranty?
A camera 3 months old? And the warranty? And the assistance? Where are there? A almost 1800 euros camera!
It's a dew problem on the sensor, sorry about that.
Please send a email to support(at)zwoptical.com, we will help you to solve it.

After all these setbacks, which force me to be inactive, I at least hope that they don’t take another month and, above all, that this recall (instead of a fair and fast replacement) has been requested to provide a really decisive control and a hardware intervention.
