The defrost timer can also make noises. It usually will make a click when it advances. As the timer gets old, the motor that runs the defrost timer can begin to make noises as well. If the timer motor is making a loud sound, then you should replace the entire timer. Noises related to the defrost timer are: snapping, crackling, or popping sounds. This is most likely caused by the defrost heater getting warm, and cold water dripping onto it. You may also hear some metallic sounding expansion or contraction creaks as the coils warm or get cool.
