1. A NO CO means that SOMETHING has stopped the refer from cooling down correctly.
2. That means you MUST find the problem or you will continue to get the NO CO.
3. You have not fried the Motherboard
4. But, until you find the reason for the NO CO, replacing the motherboard or resetting it will do no good.
5. Causes of NO CO
A. Blocked or leaking Cooling Unit
B. Ventilation behind the refer blocked or inadequate
C. Incorrect LP pressure or Dirty Burner/flue tube
D. IF you have rear cooling fan/s, they are not functioning
E. Low (below 108 volts) AC voltage
6. NO CO is a Cooling Unit protection shut down feature. Doug
