There are five LED's in the ceiling and two along each side of the refrigerator compartment and one in the freezing compartment of which (throughout my ownership of my French-door KitchenAid refrigerator) I've replaced three. The LED's are wired in series (akin unto old-time Christmas tree lights), such that when one goes out, all in that circuit are also out. The freezing compartment light is on a circuit with the two along each side of the refrigerator compartment, so that when it malfunctioned, none of the side-lighting in the refrigerator compartment functioned. The most recently malfunctioning LED was in the center of the refrigerator compartment's ceiling, which is in series with the two LED's on the right of the refrigerator compartment's ceiling. The new "LED light module's" packaging instructions advises that one is to "jump" each light in the circuit to discern which is causing all LED's in that circuit to malfunction; however, there exist no external contact points on any of the LED's--complicating that endeavor. Some LED's have individual connections (and all come, wired as such), while others are continuously wired, in which event one must cut the connection and splice the wires with the (two) provided splices. However, the wires are exceedingly short, which calls for either great dexterity, a helper or three hands: One to hold the two wires in the splice, one to hold the splice and one to close and crush the splice to effect continuity of electrical contact. It's all easily accomplished, if you've done it before--or if you inquire of Appliance Parts Pros' very helpful problem solvers.
