Refridgerator won't run on AC

check your battery ,it still needs 12v for it to work. ac,or propane.

Got 110V AC to outlet....but do you have AC to fridge at control module??

5a Fuse on module board is for AC circuit (heater) so fuse could be blown OR AC heater element has failed.

Side by Side Norcold.....model 1200?
At least it's doesn't have a Red LED light ON (recall box) cause it wouldn't work on propane either

Any error codes?
Have you used the diagnostic mode?

Best guess is A/c heater element failure. Check continuity of element

I agree with a burned out heating element. Pretty quick change-out. I did one in about 20 minutes or so and no idea what I was doing.

Shot in the dark here from someone who knows next to nothing about how things work... hehe.

I have a Norcold in my new to me fifth wheel. A week after purchase and running on AC, the fridge packed it in. The troubleshooting section of the manual didn't help at all. But the owner of the RV dealership sure did. He came out to where I am and took a look at the back end of the fridge. He unplugged everything back there. The AC plug, the generator thingie and the propane whatever. Waited a few seconds, then plugged it all back in again. Apparently, the control center of the fridge, much like a computer sometimes, needed a reboot.

Sounds like they did a hard reset.
Not something that should be needed.......but required when the Norcold doesn't work on electric OR propane

I replaced the electric element in mine a couple months ago. Cost 38-78 on the net. I salvaged one from a junked fridge.

Check the 5 amp fuse first. I have a Norcold 8142 that does the same thing occasionally.

So it looks like our Refrigerator has two A/C heater elements. Both of the wire sets look identical and both are labeled as 120 VAC heater elements. Both tested out with the ohm meter at about 73 ohms. So, I'm thinking the control board may have failed. Does anyone know of testing instructions for a board with a part number of 621271?

Thanks for the help!

Our camper neighbor just had this. Shut the refrigerator off inside. Then go outside and unplug the 110, then unplug the 12 volt. Go have a beverage and then come back - plug 12 volt back in - then the 110. Go inside and turn back on. This is like rebooting a computer. It worked on theirs - worth a try.
