I have a Norcold 1200. Was getting noco code. Smelled ammonia so we changed out the cooling unit. A new board was put on a couple months ago along with a recall kit. Also replaced the thermister and thermostat for the fans. Still not cooling and popping the noco code. Can anyone please help me figure out what is going on? Thanks so much!

I would get rid of the recall kit and wire it as original.

Good luck, happy trails, and God bless!

The NOCO code indicates that the unit has been operating for two hours with no drop in temperature sensed by the thermistor. If this occurs twice, it will lock out the heating elements until you do a reset procedure. (see link below)

Is this happening on AC, LP or both? What it indicates is there is no heat being applied to the boiler tube. Check the voltage output to the two heating elements to see if they are being powered. There is a fuse inside the control box for the elements. Check the resistance of the two elements to see if they are good. You can apply 120vac directly to the elements one at a time to see if they are heating up.

Here is a link to the service manual that may help you out.

Thanks for the replies! I tried the recall kit thing and it didn't work. :-( The heating elements and gas are both working properly. The up tube off the canister is cold and there is a lot of condensation, but the refrigerator or freezer are not cooling down. I'm at such a loss here!

Keep in mind that it can take 8 hours or more for the freezer and fridge to cool down. The freezer gets cold first, then the fridge.

if the boiler is heating and you are getting no cooling I would suspect your new unit is faulty I went through a couple of rebuilt units before I got a good one

It started working, yay. There was an air bubble blocking the absorption. I guess according to norcold if the up tube off the canister is cold and there is condensation on rare occasions that in a new cooling unit during shipping it will form an air pocket and the unit will need to be put into bypass mode. To put the fridge onto bypass mode they had me unplug the thermister, turn the temp to 9 and do a board reset. It should correct itself in 48 hours. When woke up this morning both freezer and fridge were cold. In case anyone else has this problem.
