The defrost timer acts like a clock, continually advances and alternates between activating the cooling cycle and the defrost heater. This 120V 60Hz defrost timer will cycle for twenty-five minutes after every six hours of run time. The timer itself is made of plastic, and its terminals are bent, the leads are internal, and the label is orange. If your refrigerator is too warm, freezer section is too warm, freezer is not defrosting, or leaking, you may need to replace the defrost timer. This is a genuine OEM part. Please remember to disconnect the power before starting the repair.
