I have replaced my horrible broken old fridge with a new one. This new one (Tefcold SDU1375) is quite a different beast than my old one and is much more powerful as such.
I wanted to try and not tamper with the fridge’s hardware, but I’m running into trouble with temperature control. The fridge has 7 settings, 1 through 7, which the manual says correspond with 2-12 celcius. It’s on 4 at the moment, which already allows the fridge to become super cold, and is causing oscillation in the beer temp. The fridge is only on for the minimum ON time in brewblox, but in those 3 minutes, the fridge temp drops 4 degrees and the beer 0.7c. Too much swing for me. Anything I can do? Can I make the fridge less powerful?
