Help! Have tried to reset li op code with magnet several times no luck . Unplugged wire from black box waited 15 seconds no luck . Happened before on day 3 called mobile rv tech when he got there the next day it was working any ideas?

Do you have any indication of a boiler tube failure, yellowish powder under fridge.

When my fridge started to fail I was able to reset the black box a couple times with a magnet but the last time no luck.  Looked closer and saw the powder, unplugged the fridge and quit using. 

We had a small dorm type fridge I used in the short term but ultimately replaced the Norcold with a Samsung FR18.

No indication of leak anywhere something killed my house batteries and started this issue

Sounds to me like the magic black box is not the culprit but rather something else in your control system.

The code you listed above (li op code) (does not show up in the Norcold 1200 Service Manual. It would help if you posted the actual code that shows up on your display versus what you posted.

Thanks, lots of information on the Internet regarding that specific code.

Surprised that it is not listed in their manual.
