1. You Have a NORCOLD refer, not a Dometic
2. The NO CO is a cooling unit protection shut down. That means your refer has a problem that prevents it from cooling down and throws the NO CO code to prevent damage to the cooling unit. This IS explained in the Norcold operators manual.
3. Things that will cause your problem starting with the most likely FIRST
The rear cooling fans are not operating
The ventilation on the back side is blocked
If on 120 only, one of the 2 heating elements is bad
If on LP, dirty burner or low flame and low LP pressure
The cooling unit is bad.
DO NOT fix the cause, then it will continue to throw a NO CO. Doug
