The Samsung Icemaker can throw out a lot of error codes when something is wrong, including the E-40 or 40E error code, indicating a failure of the Icemaker fan. Sometimes, this is due to ice build-up in the icemaking cabinet, but other times its due to a general fan failure - either a fan blade has broken, or the DC motor has failed. The fans listed are exact-spec replacements to these fans at a lower price than Samsung offers these fans at wholesale to their contractors.
