Dometic fridge not cooling

I know I should've searched, but I'm on my phone and the app crashes every time I try to search...
My 15 month old dometic fridge in my sabre 34tbok suddenly stopped cooling as well as it had. Im at home, plugged into 30 amp so usually leave it on electric. I switched to gas and am getting the same result. I'm wondering if I need to add fans in the outer bay add so many have? The slide (temp adj) is all the way up and it seems cooler in the mornings, but the freezer is around 20 when I get off work and that makes the fridge about 60.

Any suggestions. We've camped in hotter weather than this but never had fridge problems before?

Check to see where the probe is in the slider.
Sometimes it will slide down to the bottom of the slider when it should be near the top.

Things I've done trying to fix same issue. Added fans behind the frig to pull the heat out. Put fan in frig. Added roof flashing behind frig to direct heat to the upper vent. Replaced thermistor with "snip the tip" dial. Still not as cold as my previous non-slideout frigs.

Probe is good, I've adjusted it up as far as possible. I think I'll find some computer fans and wire up in the chimney exhaust.

Several here report that made a big difference for them. However, in my slide mounted frig, I didn't notice any difference. The only thing that was noticable was the new thermistor at Product Listings for Snip The Tip. Then find your model in the list. Under $30 if I remember correctly.
Also, I watched a video on You-Tube where a lady emphasized the importance of the drain tube sticking out the top of the vent cover with a bow in it to create a "p-trap" type condition which holds some water in the drain and prevents heat from entering the drain. Don't know how important it is but it did make sense.

The weird part is that for the 15 months of ownership, in temps between 10 & 100f, it had always worked great. Are the thermistors known to fail? I need to do some reading. I'm hoping a good bounce down the road will help as we are heading out for a week either Sunday or Monday for one last extended hurrah before school starts

Yeah. Better to be lucky than good, so I hear.
Its been mentioned that moisture can get inside the thermistor wire and wreak havoc.
