Norcold 1210 mystery

[GoneRVin]

I have the Norcold 1210 (unfortunately) and is giving me some grief.
The fridge on AC or Propane will work great for a week or so then when it starts the Temperature Control System to remove the frost off the the fins, it will not go back to cooling mode. I am not getting any error codes.
Has anyone experienced this problem, id so what was the cure.

Called Norcold and typical response, take it to a dealer, not going to happen.

For those of you who have the same fridge, you might want to check your
Thermostatic Switch, they mounted mine over the slot in the cooling fin.
As if that is going to work real well.

I am talking about the outside fans that push air up pass the condensor fins.
If you look at section 4 of the service manual it will show you diagrams of how it is setup. I found my Thermostatic switch was mounted over a slot in the condensor fins. If your fridge is in a slide out and vented out to the side, look in the opening and you will see the condensor fins, look to were they have mounted a switch to the fins, mine was about 4" in over a slot that made the switch useless. In hot weather, the fans would only run occasionally and I had trouble maintaining fridge temperatures. Now that I have moved the switch
it works a lot better.
Now if I could figure out how the board controls the warming of the fins to melt the frost I would be happy, I think the electrical board is giving up.

thanks for the link OB. It's much more detailed than the one i got with the RV.

just want a clarification. Are you talking about the thermistor attached to the cooling fins (small clamp) which senses for frig temperature??

We've got the same frig & see that temps periodically go up several degrees then go back down. We're assuming this is due to the temperature control periodically defrosting the fins as described in the manual, but it's a little disconcerting as you're not sure if there's something wrong with the fridge or it's doing what it's supposed to. Our last RV had a Dometic fridge & it maintained temperature pretty steady.

Even though there's no fault code the control board may need to be reset.

Thanks for the replies To Smart and I have read that service
manual and no mention of the way they control the heat to remove the frost off the fins.

Because you are too smart or too cheap?
