Troubleshooting Norcold 6162 Frig

Does it have 12 volts DC?
Does the eye brow light up?

There are two circuit boards, the one outside inside the access panel and the second one, the eyebrow panel on the front of the fridge where the controls are. I put up a trouble shooting step by step but I'll have to try to find it.

We ended up replacing the eyebrow on ours.

Thanks guys but the manual is of no use because I'm not getting anything. I need to be able to troubleshoot at the board level. Already replaced the power board, guess I'll just replace the eye board and thermistor.

I was hoping to be able to find a way to test the power board to see if both the new and old are good and the Thermistor. I'm a poor person so buying boards takes food off my plate, lol

Does your eyebrow light up?
Do you have 12 volts DC to back of refer?
Quit throwing parts at it!

no light on eye board. 120v outlet works but everything on frig is dead. Don't know where to test for12v. don't know how to test thermistor or even if that part matters

You test for 12V at the board that you say you replaced, at the plug that goes into it. My eyebrow board had a display it just would not change settings. Search the iRV2 forums, I had a fairly complete troubleshooting guide but I got banned for mentioning Florida's Concealed Weapons program, and no I'm not kidding so I cannot look there.
But don't keep working on this the Navy way, replace parts until it works.

No lights would indicate no 12 volt DC. 12 volt DC is used for all the controls.
See page 9-10
Manual
There should be fuse on circuit board.

It does a glass cartridge fuse there is also a thermal breaker on the stack. And if it's 120V problem you need to check the main panel breaker too. I have a model 821 tho.

If you insist on replacing parts, you will end up with a lot of money spent and still no operation.
1. Your Model has a HI HUMIDITY switch, usually between the Lower and upper Freezer doors. THAT switch usually corrodes out after a number of years. It has a ON with Humidity heat strip ON and ON with the Humidity strip OFF. with a MIDDLE stop. IF that switch corrodes out and the UP or Down does NOT send the 12 volt signal, the Refer appears DEAD. MOST common fault on Old this type model Norcold. You bypass or replace the switch.
2. Until you get a Volt meter and verify that you DO have 12 volts on the back side 12 volt input wire, you are spinning your wheels. If NO 12 volt on that wire, you have a 12 volt fuse at the fuse panel for the RV bad.
3. HAVING 120 AT THE REAR RECEPTACLE MEANS NOTHING. The refer controls operate from the 12 volts of the RV. Doug
