Low Medium High

Code Meaning Severity Common Symptom

FL Water flow or fill fault Medium Restricted water flow causes the ice mold to receive less water than needed, resulting in undersized, thin, or flat cubes that are smaller than normal View FN Ice maker fan motor error High Without the compartment fan circulating cold air, the mold temperature rises and freeze times become excessively long or incomplete, causing production to halt View HS Harvest sensor fault Medium The ice maker begins a harvest cycle but stops partway through, leaving cubes in the mold or partially ejected, because the harvest sensor signals an incomplete release View IF Ice bin full sensor fault Low The ice bin is empty or nearly empty but the ice maker has stopped cycling because the full sensor is falsely reporting that the bin is at capacity View IS Ice maker temperature sensor fault Medium The ice maker halts production entirely because it cannot confirm via the sensor that cubes have frozen to the correct temperature before attempting a harvest View TE Ice maker temperature sensor fault Medium Without a valid temperature signal the control board cannot determine when the mold has reached freezing temperature, so it halts the production cycle as a failsafe View
