How long does defrost cycle last?

The defrost cycle in a refrigerator or freezer typically lasts between 20 to 30 minutes, although the duration can vary depending on the appliance's design and the amount of frost buildup. Many modern units use automatic defrost systems that activate based on specific time intervals or when the temperature reaches a certain threshold. If you're noticing longer defrost cycles, it might indicate a problem that needs attention. Regular maintenance can help ensure optimal performance.
