Abstract
An ice maker for forming ice having a refrigeration system, a water system, and a control system. The refrigeration system includes 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. The water system supplies water to the ice formation device. The control system includes a controller adapted to operate the condenser fan motor at a first speed in a forward direction when the ice maker is making ice and adapted to operate the condenser fan motor at a second speed in a reverse direction when the ice maker is not making ice. Operating the condenser fan motor at the second speed in the reverse direction is sufficient to reduce the amount of dirt, lint, grease, dust, and/or other contaminants on or in the condenser.
