Bimetal for refrigerator is a temperature sensor that is utilised in refrigerators and other appliances as well. It is made up of two strips of various metals, like steel and brass, that have been bonded together. The strip bends because the two metals' differing rates of expansion and contraction in response to temperature variations. This bending is used to turn on a switch that operates the refrigerator's compressor and fan. The bimetal for refrigerator is often found next to the evaporator coil, which removes heat from the appliance. It will bend and the compressor and fan will turn on to maintain the right temperature inside the refrigerator.
