Product review (1 stars): Good thing we were home
Light started burning.  First, the light wouldn't come on.  For days.  Then it suddenly came on this afternoon - and didn't turn off. We smelled something burning; opened the fridge - and whammo! The housing was melting and had dropped from the ceiling of the fridge.  The light bulb sockets were scorched; the unit was warped, and it had melted off of the screws to the point it had dropped into the fridge.

Good thing we were home.
