Ice Maker Process
The GE ice maker operates on a cycle that spans up to 90 minutes. The system begins by chilling the ice tray to just below 36 degrees. The tray fills with water, then the cubes freeze. It can take an average of 75 minutes for the ice cubes to freeze completely.
When the ice cubes reach a temperature programmed into the ice maker, the system automatically purges the tray. The ice tray warms to slightly above 36 degrees to break the cubes free. Once the cubes are loose, they dump into the bucket underneath. If ice cubes fail to release after 7 minutes during the clearing process, the ice maker defaults into a repair mode.
If an ice cube does not release, the ice maker is unable to reset the system and begin a new cycle. The clearing process waits 7 minutes before triggering a repair cycle. The tray warms to between 59 to 68 degrees in an attempt to melt the ice that is clogging the ice maker. The repair cycle runs for up to 23 minutes before launching fault mode. The motor runs for 50 seconds of every minute trying to clear any ice stuck in the tray.
If all attempts to clear the ice tray fail, there are several possible reasons. If the heater on the tray fails, the cubes will not break loose. The ejector that dispenses the cubes may fail, requiring replacement. The motor and its control board are necessary for proper function. A failure among those parts can leave the ice tray out of commission. An appliance repair technician may be necessary for component failures.
