Product review (5 stars): Quick 1 minute replacement job
This was so easy to replace in my Subzero Model 590.  I just used a slotted screw driver to carefully pry out the old switch, pulled out the connectors, attached the wire connectors to the new switch, then pushed back in the new switch.  You don't have to take off any of the paneling or trims.  This is an identical replace part as many refrigerators of a wide assortment of brands use the same components.
