1-Bad-57,
Looks like your 'n' code might occur if 1) the unit is not level, 2) there's inadequate ventilation at the rear of the unit, 3) possibly no air circulation inside the unit, 4) a bad cooling unit.
If you recycled power without correcting the problem, the refrigerator is designed to lock in a disabled mode, presumably to prevent damage. The reset procedure is pretty complicated and probably better undertaken by a service tech.
If the underlying problem was 1, 2, or 3, and has been corrected, then a going to a dealer on the road might get it going again. If it needs a new cooling unit, things will get more interesting.
As an alternative, you might try the following procedure, which may apply to your model. Before doing this, make sure the unit is level, there is nothing blocking airflow at the back, and that the interior is not tightly packed with stuff.
Read all steps and make sure you understand all steps before actually trying it. If the instructions don't correspond to your unit, stop and turn the unit off.
If the refrigerator restarts and then kicks another n code, do not keep resetting. You could cause permanent damage which might not be covered under warranty.
There's a chance you could get past the lockout by erasing the fault code. To do this, go to diagnostic mode:
To access the Diagnostic Mode:
1. Press and hold both the MODE and TEMPSET buttons at the same time.
2. Release the MODE and TEMPSET as soon as screen 1 displays.
3. A few seconds later, 8 displays.
Changing Screens
To change screens, press the MODE button until the next screen displays.
You want to go to screen #6
Screen Erase Fault History Data
Screen 6 provides a way to erase stored fault history from memory. To erase stored fault history:
1. Press and hold the TEMPSET button when E and r display.
2. Release the TEMPSET button when C and L display.
3. Wait five seconds.
4. Press and hold the TEMPSET button until E and r display again.
Press the MODE button to bring up screen 7.
Exiting the Diagnostic Mode
To exit the Diagnostic Mode:
1. Press and hold the MODE and TEMPSET buttons at the same time.
2. Release the MODE and TEMPSET buttons as soon as the LED segment that represents the selected operation mode appears on the display (AUTO, AC, or LP GAS).
Turning the refrigerator OFF then back ON also exits the Diagnostic Mode.
