The RS2556SH is self-defrosting, so this should happen automatically. If what you're experiencing is more significant, however, and the freezer temperature has risen dramatically without the control panel being changed, it may require service. First, please make sure the temperature on the control panel has not been changed and the doors have not been left open. If service is necessary, please submit an online service request through the link below, or call 800-SAMSUNG to speak with an agent who will be happy to assist you.
