I identified the Fridge model number (GE, TBX18SPE) from the tag inside the Fridge, then used the parts diagrams and list on Appliance Parts Pro website to identify and order the correct light socket. The part arrived in about two days, and was as advertised. Installation was very easy. First I checked the hole where the light goes, found the light wire plug, pulled the light plug out of the hole a little bit, mated the light plug to the new socket, then inserted the socket into the hole until the retention tab snapped into place. I installed a new appliance light bulb and was done. The light works great now.
