Sub-Zero Clumping Ice on Dispenser Models


  • Ice is sticking together in the ice bin
  • Ice will not dispense because it is fused together
  • Ongoing issues with clumping ice in ice bin


For clumping ice cubes in any dispenser model, verify the following first:

  1. Clean the Condenser.
  2. Verify freezer setpoint is 00°F or lower.
  3. Verify doors and door seals are free of tears and debris.
  4. Verify the mullion chute door that delivers ice from the freezer to the dispenser operates freely (opens and closes).
  5. Make sure the ice maker is always left on.
  6. The more ice dispensed, the less it will clump – if unused, even for a period of a few days, ice will fuse together as the freezer runs through defrost cycles.
  7. Empty, rinse, and dry the ice bin 1-2 times per month in order to remove the ice particles created from auger movement.
  8. Make sure water filter replaced as required.
  9. Verify water pressure to unit is steady between 20 – 100 psi, for Classic (BI) models 35 - 120 psi.

Some clumping is normal, if a shake of the ice bin frees the ice cubes, it is probably normal ice clumping.
