how long is the defrost cycle on a fridge
On Adaptive Defrost Controls, when the heater shuts off, shortly after the machine exits defrost mode. Basically if the heater only stays on for ten minutes, the whole defrost cycle will only be about 12 or 13 minutes long. Basically when the heater comes on, it starts to melt the frost on the evaporator. Once all the ice and frost is gone, the temperature behind the panel will start to rise.
