The Whirlpool W10843055 functions as the control board for your Whirlpool refrigerator. The temperature sensor, door ajar sensor, and other sensors inside the refrigerator send signals to this intricate circuit board. The control board uses these signals to interpret them and sends instructions to the compressor and evaporator fan, among other refrigerator parts, to keep the refrigerator compartment at the ideal cooling temperature consistently. A broken control board can cause a number of problems, such as inadequate cooling, odd noises, and even the refrigerator breaking down entirely. The Whirlpool W10843055 control board can be used to replace a malfunctioning one, ensuring that all of the refrigerator's parts work together properly to maintain your food cold and fresh.
