This Avantco 19491253 fan blade is a direct replacement for the one that came with select Avantco Ice MC-H and MC-F series ice machines. It is a vital part of your unit's refrigeration system, working with the other components to help your unit dissipate heat and keep the cabinet set to the right temperature. A broken or malfunctioning fan blade can prevent your unit from maintaining specifications and cause strain on other components, so be sure to replace it promptly.
