The fridge seems fine: Ice blocks cut hidden strain on motor

Frequent door openings cause sudden temperature spikes inside a refrigerator, forcing the compressor to work harder to cool the interior back down. This cycle increases electricity bills and can shorten the lifespan of the appliance's motor. To stabilize the internal climate, users can employ a simple physical buffer: frozen water containers. Because water has a high heat capacity, a solid block of ice acts as a thermal battery. When the door opens and warm kitchen air enters, the ice absorbs this excess heat, preventing the internal temperature from rising sharply and reducing the frequency of compressor startups. Engineer Aleksey Tikhonov notes that ice is more inert than air; it holds the set temperature longer, whereas empty air warms up instantly.
