Thank you for your post, gene!

Based off the information you have provided the light inside of your Frigidaire refrigerator is not working. This could be a problem with the wiring harness or your socket. You can perform a reset on your refrigerator by unplugging the power cord and plugging it back in this will help clear out any miscommunications within your refrigerator. If this does not help resolve your issue I would recommend having a professional technician out to perform a proper diagnosis and repair. This will prevent you from purchasing unnecessary parts.  Hopefully this is helpful. –OOS
