Norcold Fridge Only Cooling on Shore Power in 2017 View 24J

As already stated by great folks that you need to find the model of your frig. Richard gave you information to start with. I would take that info and call Lichtsinn RV (the go to Winnebago folks) and ask about the frig.

You should be able to look at the back of the frig through the outside access door. There are fuses there in some sort of plastic box. Also do not know if your frig is covered under this safety add on or not. If so there may be a small black unit that will have a blinking light. That unit is made to shut off the propane when things get to hot. If thats your case you may need to reset that piece of equipment.

Good Luck

The Norcold 'safety box" turns off 12VDC to the control board, effectively turning off all fridge operation.

Wow - great information. Thank you all. So - interesting enough, I pulled and checked the 12v side of the fuse box. There were two fuses labelled fridge, one was a 3amp and another was a 20amp. I pulled both and tested with my ohm meter and both checked good. But here is the weird thing. I went back to the fridge, and the panel was working. Cycling through the settings, propane - green light came on, 120v AC - green light, and then on battery - red flashes (wrench code 7). But then I came in and saw Morich's second post, and I did not test with engine running - but - I think - and have no clue why, but removing and resetting the 12v fuses most likely fixed what ever was funky. Is that possible ?

Low voltage connections, which includes 12v, can corrode easily during periods of non-use. When you remved the fuses and reinstalled them, you effectively "cleaned" the connections.

Bottom line despite the drama, use a multimeter. When it is under a load. Perhaps this is why the engine needs to be running as it has a better chance of having greater then 13 volt.

Why are the time stamps so far off on these posts?

 

[Morich]

The times not off, I'm just out of sync with the rest of the world?
That time is correct at some point in the world, just not the one I'm in!

The directions have a small point on operation that is new to me. Might be part of the hangup? Running down the road I would have assumed okay on 12VDC but when we stopped and plugged to shore power, does it switch to AC or does it take manual change?

Seems it might be easy to run on propane while driving and then assume it working after we stopped? But any automatic change to propane would depend on having the propane valve open!
Lots of small points for each type frig and I would have to read carefully!

Rich,, that refers to the 12VDC cooling unit operating with DC cooling only.
TimothyPaul, if the display is blank there is one of a few things happening. First is no 12VDC to the frig means nothing works because the PC board is 12V powered only, unless the 120VAC cord runs directly the the heater on the side of the chimney.
The other reasons are addressed in the troubleshooting section of the service manual, which can be found here:

Yes, simply removing and replacing 12V fuses can "clean" the contact areas of the fuse and holder.

It would also reset the board
