Make sure the thermister is attached firmly to the fins in the back. The boards on a Norcold can be reset a service center familiar with this process is your best bet. It takes disconecting the board and then shorting it out best to leave it to some one who is familiar.

Is there a switch so you can switch the unit to operate on ac? There might be, and it is switched to operate on dc right now.

Hi, With the information you supplied i'm going to assume there is an ice build up at the rear of the freezer. Your problem is going to be with your defrost system. I will also assume you have the ability to repair this yourself. This is going to be one of three problems with your refridgerator, 1st thing to do is remove shelfs and panel in the back of the should see ice build up on the evaporator...don't worry get a hair dryer and melt the ice. Next locate the wires for the heater...using a multi meter test the heater for condinuity...if the heater is bad replace it, If the heater is good replace the defrost thermostat..the stat normally is a barrel looking part clipped onto the evaporator pipe. The last possible problem could be the evaporator fan, have you heard the fan running in the past few hours?..if you are not sure pull the panel out to where you can see fan and watch it over an hour to see if it turns. I have included links with pictures of what the parts you need to check are: defrost stat heaters evap fan. Hope this helps. If you have any other questions please feel free to comment again. If you decide to get a repair guy in should not cost you any more then $120 - $200 depending on make/model/problem Good luck & thanks for using fixya!

I shut down the fridge. Not getting any power to it now. I have checked breakers and fuses. There is power to 110 outlet where it plugs in. No power to gas valve. What do you think the problem is?

Your Norcold refrigerator is powered by 12V DC, not 110V AC. You need to check input power at the power board. If the fuses are good and you have good 12V to the refrigerator, check to see if you are getting 12V past the 5amp fuse on the board. If not, you may have a bad board.

Norcold fridge in my motorhome

Norcold fridges are now part ofThetford one of the largest suppliers of mobile and marine products. You do not quote the model so not sure if a 3 way (gas/mains/12v) or AC/DC. The most common problem with all mobile fridges is the heater unit is faulty. Thetford have discontinued spares for a large range of norcold models. Information can be obtained on the website.
Good Luck

No power to refrigerator unless it is hooked up direct. Think it is 12 volt dc supply connection. Could this be the problem only able to get partial # on part c1c 5122 is all we can read.

there is an inverter built in to the power supply that converts dc to ac to run the compressor if the fuse is ok. you will have to replace the supply . or for traveling you could hook up a small inverter to opperate the fridge while traveling this could be connected to the 12 vlt line for fridge power as it will not take much more power than the the fridge needs.

I have a Norcold 323 Refrigerator in a camper that will not cool when operating on AC but does work on gas, ( I cant test the DC as I dont have a 12 volt power sorce). After running in on gas for a while...

the unit runs on gas(LPG) so the unit is operational
by ac I take it you mean mains power and by dc you mean 12 volts it being a 3 way cooler
you cannot "jump start" a gas system so I am a bit lost with that statement
check the heating element in the unit for continuity as both the mains and 12 volt power only heat and element that boils of the coolant liquid in the system the same as the lpg flame does
it could be a relay problem for the electrical part
