Ice maker with reversing condenser fan motor to maintain clean condenser

An ice maker for forming ice, the ice maker comprising:

• (i) a refrigeration system comprising a compressor, a condenser, an ice formation device, and a condenser fan comprising a fan blade and a condenser fan motor for driving the fan blade, wherein the compressor, condenser and ice formation device are in fluid communication by one or more refrigerant lines;
• (ii) a water system for supplying water to the ice formation device;
• and
• (iii) a control system comprising a controller adapted to operate the condenser fan motor at a first speed in a forward direction and adapted to operate the condenser fan motor at a second speed in a reverse direction to reduce the amount of dirt, lint, dust, and/or other contaminants on or in the condenser;
• wherein the controller is configured to:
• turn the compressor on and begin operating the condenser fan motor at the first speed in the forward direction to cause the ice maker to make and harvest consecutive batches of ice,
• determine when the ice maker has been operating to continuously make and harvest consecutive batches of ice for a predefined interval of time;
• in response to determining that the ice maker has been operating to continuously make and harvest consecutive batches of ice for the predefined interval of time, execute a condenser cleaning operation in which the controller:
• harvests the ice from the ice maker by performing an ice harvesting operation;
• and
• after performing said ice harvesting operation, turns off the compressor;
• and operates the condenser fan motor at the second speed in the reverse direction while the compressor is turned off.
