RV Fridge Thermistor Replacement?

I used one for several years with no trouble at all.  I had to replace the whole refrigerator recently because of the dreaded yellow leak. I never have liked the slider adjustment and it always needed adjusting.  I will get another Snip The Tip when I get fed up with this slider.  The kit has good, simple instructions and has all you need.  I'm not familiar with refrigerators with a set temperture.
