The breaker strips are located just inside the front of the refrigerator case, near where the door seal makes contact. If the breaker strips are warped or cracked, they may allow moisture to get into the insulation between the inner and outer walls of the refrigerator.
Before removing the breaker strips, unplug the refrigerator to avoid an electrical shock hazard.
To remove the breaker strips it is important to bring them up to room temperature first. If they are too cold they will be brittle and may crack. To warm the strips you can open the freezer and allow it to come up to room temperature (wait 2 to 4 hours) or you can soak a towel in warm water and hold it against the strips to warm them.
