Dangerous problem with the 2024 Tab 400 refrigerator

edited August 2025 in Air Conditioning & Refrigeration
The temperature in our refrigerator remains at 50 degrees Fahrenheit, which is very dangerous for food poisoning. Our dealer asked us to set the control to level 7, the maximum. This doesn't work, and it's especially illogical to set the control to maximum, giving the compressor no respite. The manufacturer is said to have a solution by adding a fan to ventilate the compressor. Newer models supposedly have this type of modification. Are you aware of this problem, which is very dangerous for our health?

    Another "things a dealer says".
    Check this thread and the discussion of the "drip tray" and see it it helps.

    @Jautotte, we just returned from a 4 day trip to Maine's Katahdin Woods and Waters Nat'l Monument in our 2024 400 BD. Daily temperatures were close to 80 degrees but the refrigerator kept a steady temperature in the mid-30s on a setting at about 4.75 on the control dial. The compressor cycled normally and definitely didn't run continuously. We do remove the freezer condensation drip tray per the link that @pthomas745 cited. Assuming we have the same refrigerators, yours should perform in a similar manner unless you are using it in very hot circumstances. Is yours still under warranty?

    I have never had that issue with the fridge in my 2024 400.  Even in hot weather.  Do you accidentally have the fridge in the “vent” position rather than the “locked” position?  If it is in vent then it would not cool properly.

    @Jautotte I'm not certain which model you have but the isotherm 1400 has two sliding vents built into the drip tray under the freezer element. You can open and close these to increase air flow to the fridge section. Just wondering if you are sure those are open and not blocked by tall food items, if in fact you have a similar setup.

    @Jautotte just a quick moderator note concerning the title of this discussion thread. The word dangerous implies that perhaps ALL models like yours are experiencing issues with maintaining proper temperature. I think from the posts of others with your model trailer we can say that is not true.

    What IS a concern is the advice provided by your dealer. Unless they have a manufacturer notice about the issue and a recommendation in writing I would not consider what you were told to be valid.

    Bottom line please edit your title to remove the word “dangerous “, or I can if you prefer.

    This is indeed very dangerous, the dealer informed NuCAMP. The problem was encountered in the TAB 400 of the year 2024. I suggest you put a thermometer inside with memory to know the real temperature. The manufacturer must send a ventilation kit which will be installed by the dealer at the rear to ventilate the compressor.

    Thanks for the clarification. Did the dealer state it was a formal recall? Did they provide you with the documentation?

    We want to get it right to inform members of the forum.

    @Jautotte, a good suggestion was made above by @XenanMe regarding the refrigerator door latch position. I was unaware of the two options until someone on the forum pointed them out, and perhaps you are also unaware. It takes a bit of upside down head turning to see the sliding latch plate at the top of the door opening. The "vent" position allows the door to stay partly open after shutting it. The "lock" option keeps the door fully closed and sealed. My report above reflects having kept the latch in the "lock" position. During earlier trips when we inadvertently had the latch in the "vent" position, we were dismayed at how warm the temperature stayed in the refrigerator. The difference is quite noticeable. I also commented above that we now remove the freezer condensation tray while traveling and replace it after returning home. Now the refrigerator performs well once we became aware of these two features.
     (As a side note, we found that the door on our refrigerator stayed firmly closed while traveling when the latch was in the "vent" position but could be forced open by contents inside when the latch was in the "lock" position, so I added a stop pin at the top of the door that we insert while traveling and remove at camp.)

    Could you please tell me more about the stop pin mod that you’ve added? Had my (full!) fridge constantly opening on our return trip last weekend over bumpy roads, and don’t want to deal with that mess again. I was ready to install some d-rings to rig up bungees, but I like the idea of a stop pin. Just can’t quite picture it.

    @Bayliss, thanks for searching that out. Saved me posting anew.
    @maxwellllll, the cotter pin has been working well for us. You'll need to drill a hole through the plastic top frame that's aligned with the hole just below in the top of the door - same diameter.
