Understanding the Role of the Drain Hole
The hole at the back of your fridge is called the drain hole or defrost drain. Its primary function is to collect and dispose of water that accumulates inside the fridge during the defrost cycle. The defrost cycle is a process where the fridge’s evaporator coils are heated to remove ice and frost that have built up over time. As the ice melts, water droplets fall into the drain hole and flow out of the fridge.
The Defrost Drain System
The defrost drain system consists of a few components, including the drain hole, a drain tube, and a reservoir. The drain tube connects the drain hole to the reservoir, which is usually located at the bottom of the fridge. The reservoir collects the water and allows it to evaporate, preventing it from accumulating inside the fridge.
