A lack of ice can also be due to a Sub-Zero ice maker freezing up from ice jams. As an ice maker produces ice, there may be small amounts of water or slush that are not completely frozen as the ice is harvested. This slush can freeze on the ice maker and block new ice from falling into the ice bucket.

To reset a Sub-Zero product:

  1. Turn the unit off at the control panel. For units with a dial control, turn the knob to zero (0) or off.
  2. Turn the home circuit breaker to the unit off for 30 seconds and back on again. Retest the unit operation.
