Every Norcold refrigerator has a specific power board and optical board. They are completely proprietary with eachother because they need to communicate back and forth. This kit will work on any N82X/N62X model refrigerator that has an obsolete optical board assembly. This is determined by the serial number located on a decal inside the refrigerator box. If your serial number is below 9126825, this is the kit you need. If your serial number is above 9126825, you need:

Norcold refrigerator would not shut off
ordered part for model N821 refrigerator which I received in 3 days and installed it using the instructions included. Had a little trouble as the instructions cover many different models but was able to get it installed and now the refrigerator works like new. You need to read the instructions a couple of times and it would help to label the wires as you remove them as to what they are.Then when you put them on the new board you know which wire they are talking about

yippee the fridge works!
bought used 5th wheel from owner who did not know what a screw driver is. still fixing things that were bandaid and duck tape repaired. kit performed as advertised. directions a little confusing if you are not mechanical. limit switch jumper needs to be mentioned in directions. read everything FIRST. mark every wire as you go and you'll be ok. i'll be back.
