Consider that you have a banana that you have just taken out of the refrigerator at 4°C. In the first minute it rises 4°C to 8°C. During the next minute will the temperature increase another 4°C, more than 4°C or less than 4°C, why?

Welcome in. Strange question. Surprised core temp gained 4 degrees in first minute.

The difference between the banana and ambient temperature is less, so heat transfer will be slower.
 
4 degrees C is about 39 degrees F. I recall an old Chiquita banana commercial "bananas like the climate of a very very tropical equator so you should never put bananas in the refrigerator".

4° is too warm for your fridge. Milk will spoil rapidly and meats would be unsafe. You need service or replacement.
