Post number 3 is correct plus the link needed to reset. Easy solution. Post number 4, is partly correct. You can get the NO CO without any problems related to it. Just reset it and continue on. If you really do have a problem it will come later.
In my case it happen, reset twice, after that no problems for 4 years, then we decided to go with a residential
MY post is dead on. The first NO CO it locks out the refer. You just turn the refer OFF for 1 minute and turn it back ON. IF the NO CO problem is NOT corrected, it will throw the 2nd NO CO and will LOCK OUT the controls and you have to do the Hard reset. The NO CO is a cooling unit protection shut down. What it means is simple---The refer did/can not do a complete normal cool down. That meaans there is something wrong with the refer system---inadequate ventilation (fans) Low LP pressure, one of the 2 heat elements is out, ANYTHING that causes a NOT normal refer cool down. Running off level can possibly cause that. But, as I stated, you turn it OFF and if you corrected the level problem will then do a normal cool down. AFTER the first NO CO, if the refer does a normal complete cool down, the first NO CO is erased from the system. Doug
