We bought a new Samsung RF24HSESBSR fridge/freezer a few weeks ago, but it had a coolant leak that meant the freezer couldn't work as intended.
We got a replacement a few days ago, and being extra cautious, I have been monitoring the temps.
It seems the temperatures being read by the fridge don't match what standalone thermometers are reading. This morning the fridge was saying -22ºC for the freezer and 1ºC for the fridge, but my thermometers said -19.5ºC and 6ºC.
When I turned the power off for 30 seconds to reset the fridge, suddenly the fridge readings match the thermometers.
