After a little fiddling around, I managed to get around it by setting the cooler to say -6, and watch the cooler power drop quickly to say 50%, while the sensor temp remained quite cold, then set it back to -35 pretty fast. Like fooling it into working?
Tried both DC 201 power supplies and same problem? Any ideas?

Do a test inside & measure the voltage on the 12V power supply
as you adjust the temperature lower & lower.
Even a poorly connected fuse could cause that.
