We cover the components that help the unit freeze the food within, but we don’t cover secondary functions like ice production, so we do not cover ice makers, crushers, or dispensers. Parts for some models are available online through our partnership with Encompass.
We also do not cover lights, which are handy but do not affect the performance of the freezing mechanism.
