Review: Good replacement - Fixed my mini fridge, works fine and temperature is consistent. Follow other reviews for proper wiring. Used to replace a 2 pin thermostat. This is for a 3 pin but you can use it, I did and works fine.
Review: Vissani MDFF7SS Direct Replacement - I have the aforementioned fridge above, I got it when it was newly introduced for $177 which was a steal. The thermostat didn’t work right from day one. Wouldn’t cool the fridge below 40 degrees which was not acceptable as the minimum temperature for refrigeration is 40 degrees. I adjusted the screw on the thermostat as per the service manual…. Still didn’t fix it. I dealt with adjusting again and again for a year until I looked for the part, and found it was unobtanium. A bit of research led me to this thermostat: it can do light cooling for the first 1/3 of its adjustment, and for the further part of the turn, but about 1/8 a rotation from Max, it does refrigeration quite well, the last 1/8th of a turn is freezing, froze my iced tea gallon solid along with everything else in the fridge, so this is a real all purpose cooler/fridge/freezer thermostat. It’s well built and grounded as the original ones are, so the safety is good. The value for the price is phenomenal, I am purchasing 2 more spares.

### ⭐⭐⭐⭐⭐ Did the trick !
*by J***S on January 12, 2024*

One of our mini-fridges stopped cooling, and I was afraid we'd have to replace it. A quick peruse of Amazon, this little doohicky, along with a *very handy husband fixed it right up ! Fridge is running like a champ, and I'm super pleased ! *very handy husband not included, therefore, some results may vary.
