Do not operate the refrigerator until the installation is complete. In cases where the freezer temperatures range between minus 20°F and minus 35°F, and the fresh food temperatures are constant or range intermittently between normal and 60°F, the fresh food damper may be stuck in the closed position. In this case, the sealed system will continue to run, attempting to cool the fresh food compartment. This will cause sub-zero temperatures in the freezer compartment and may lead to freezing in the icemaker fill tube. The damper may have failed to close, failed to open, or may be only partially open. To correct this situation, replace the fresh food damper. Side-by-Side models use one of three main, fresh food compartment dampers. The bottom-freezer models have one damper. See the table below for the correct replacement part. Also, in cases where the fresh food compartment temperatures range between normal and 30°F and will not increase regardless of control setting, the damper may be stuck in the open position which can lead to a frozen water tank and no water getting to the water dispenser or icemaker.
