What fin for thermistor in Norcold N612 fridge

My Norcold N612 was been running warmer and I moved the thermistor up the fin about 1 inch. Now it's really up about 8 degrees warmer still. Where exactly does the thermistor belong? Is it fin 6 half way up? And how do I make it colder?

  • Just came back from a beach trip. Fridge is working great even in the heat. Freezing my jug of lemonade. Have to turn it down a notch or two. Had the fridge down to 29 in the morning.
  • I usually freeze a gallon water jug and put it in the refrigerator, turn the Dometic on, and go grocery shopping in route at a wal mart, which ever one it is I spend the night in the first night. Get up in the morning and go shopping, after the fridge has been on all night.

    Jug of frozen water comes out when the food goes in.

    I assume you know that an empty refrigerator will not hold its coolness worth a hoot... so, do you have some bottled water or anything else inside there? That fridge needs to have stuff in it to really show you what it can do.

    My Norcold (in previous TT) was not getting cold enough, so as an experiment I tried hanging a fan outside the upper vent to suck air out that vent (pulling cooler air in lower vent). The fridge temp dropped 18 degrees. If you try this and it works, just wire a computer muffin fan into place inside the vent and let it run.

    Another way to cope, at least on a temporary basis, is to freeze a gallon jug of water or two and place in the fridge before you leave. Of course, if you are camping in hot weather this ice won't last more than a couple of days; but if you're headed to where it is cooler the fridge will also be cooler.


    Far right fin......Dometic

    2nd, 5th fin, 10th fin....Depends on which Norcold Model
  • It's working fine now. Moved it back to where it was. Cooled off here and the temp is now down to 34 in the fridge and 0 in the freezer. Going to start packing the fridge for the trip so everything gets really cold overnight.
    Thanks

    Moving thermistor UP/DOWN doesn't work on a fridge that has an adjustable temp control.

    With it on 6th fin the thermostat was not getting correct temp sensing.
    With it now on 10th.....should be cold in food compartment by departure time.
  • Do you get the same results on both gas and electric?

    A couple of years ago my Dometic would not cool well on gas. Found the regulator was bad. Low pressure caused low flame and box at 50 degrees.

    Cooling on electric (120 volts AC) was good.

  • 10th fin mid-position

    What temp set point do you have it on? 1-5 (coldest)
