Received this dual doors dual temperature control wine chiller with some unusual issues:
1) On powered up, all the electronics seemed to be working properly - lights, temperature settings, current temperature, etc, all displayed correctly. But sometimes both zones will get chilled, sometimes upper zone only, and sometimes lower zone only. The temperature displays will show the correct temperature as it chilled (I placed a stand-alone thermometer inside and they compared correctly)
2) However, the chilling does not stop at the set temperature.
3) When both zones are chilling, there is a periodic click-on-click-off sound at every 10-20sec intervals, suspect from the solenoid.
4) If only a single is chilling, there is no such click-on-click-off sound.
I did some googling and found this youtube that appears to be the same controller: https://www.youtube.com/watch?v=7zxgGCip8ms
But compared to the PCB i have, it seems to be missing the wires connection for NTC1 & NTC2 connector (presumably the temperature sensors for the respective zones).
Is this the root cause of these inconsistent and unexpected behavior?
