Cause:

  • Excessive freezer compressor run

  2. If temperatures are near normal:
    • Clean the condenser.
    • Press and hold the door ajar alarm key for 15 seconds to clear the error code.
  3. For Designer (Formerly Integrated) products, make sure the kickplate is not completely covered by the custom toe kick or enclosed in custom cabinetry.
    • Even if the unit has worked like this for years, it can cause issues, including sealed system failure.
    • Refer to the Sub-Zero Design Guide for design specifications.
