Most of the time we think of the refrigerator as something that takes care of itself. It continues to run at the same reliable temperature month after month, year after year, without needing any maintenance at all. At most, you wipe it down and maybe even clean the condenser coils from time to time, but the fridge hardly changes. Unless, of course, you need to reset the temperature control thermostat. The temperature controller in your fridge determines just how cold the refrigerator compartment can get.
