Owner - Please keep these instructions with your Owner's Manual for future reference.
These instructions describe a "cooling unit sensing" feature which may not have been in the original controls of your

Operating the Refrigerator Controls

(N64X, N64X-IM, N84X, N84X-IM, and 1200 models)
Cooling unit sensing:
The controls have the ability to sense the operation of the cooling unit. If the controls sense that the cooling unit has stopped
cooling:
- The heat sources to the cooling unit are turned off and are locked out by the controls.
- An audible alarm starts.
- A fault code "no" "co" shows in the Center display.
You can reset the controls and remove this fault code one time.
To reset the controls, shut off and then start the refrigerator.
- To turn off the refrigerator, push the ON / OFF button for two seconds and then release.
- To turn on the refrigerator, push and release the ON / OFF button.
If you reset the controls and the fault occurs again before the refrigerator completes a full cooling cycle:
- The heat sources to the cooling unit are turned off and are locked out.
- An audible alarm starts.
- A fault code "no" "co" shows in the Center display.
- This time you can not reset the fault. Have the refrigerator serviced by your dealer or a Norcold authorized Service Center as
soon as possible.
