Lost 12 volt power to my Norcold refrigerator. Pretty certain it's just a blown fuse but can't find where it's located other then the inline fuse and the one the circuit board. Don't have power ahead of these 2. Anyone know of another? Thanks

Which Model of Norcold?

Does it have the Recall Box ....is RED Light ON?

Have you checked DC fuses in the AC Power Panel?

Is there a DC Panel in bedroom, bathroom etc
**DC for fridge is going to be from a DC Fuse Panel inside the RV (house battery) and NOT Chassis DC

Thanks for the reply, am not using the recall box. Installed a fridge defend, model 1200lrim. The ac breaker box has a breaker for the ac power but no 12 volt fuse for the refrigerator and all fuses check out O.K.

Open cabinets, look around bedroom, bathroom etc
You have House DC Fuse Panel somewhere

There is a 12 fuse box right next to the 110 volt breakers, however none are marked refrigerator and all the 12 volt fuses check out O.K. Thank you

How did you check the DC Fuses?

Visual or actually use a voltmeter, tester etc?

Did you check that the Fridge Defend was getting DC and Passing DC onto fridge?
12VDC IN....RED
12VDC OUT....Yellow
Ground...Green

Does the fridge interior light come on when you open the door? It runs off the same 12volt source.

That would tell you straight away if the main 12 volt fuse is good.

The DC fuse box is the one next to AC panel breaker box.

Use a test light and check for power on both sides of fuse, as well as the old style glass fuse on the controller board.

You could take a long wire & try and make a jumper from the house batteries to the inline fuse, see if fridge will run. If so then it's not related to the fridge..

The board could be toast....

It's not related to the fridge, I did make a long jumper wire and ran from the batteries to the fridge and it runs fine. However I would like to find the fuse for the original source. Thanks

Just touching back to possibly help someone in the future. On my coach there is a reset button on the right side of the Battery Control Center fuse box in the battery compartment. Simple push of the button restored 12 volt power to the fridge. Thanks to those who responded to this thread.
