If your GE Monogram built-in refrigerator has no interior lighting, dim LEDs, or sections of the tower lighting that have failed, the tower LED assembly is the component to replace. Part number WG03F09490 is the OEM tower LED assembly for compatible GE Monogram ZIS, ZISS, and CSB series built-in refrigerators — the integrated LED light tower that provides bright, energy-efficient illumination throughout the fresh food compartment. WG03F09490 supersedes WR55X43306 and is the current OEM part number for this application.

Important Compatibility Note: If your refrigerator has a serial number beginning with DV030000 through DV030089, order WG03F08471 instead of this part. Contact us with your serial number if you are unsure which part applies to your unit.

The WG03F09490 tower LED assembly is the vertical light column installed inside the fresh food compartment of your GE Monogram built-in refrigerator. It uses energy-efficient LED technology to provide bright, natural-spectrum illumination that minimizes eyestrain and makes it easy to locate items at any shelf level. The assembly integrates directly into the refrigerator's interior tower structure and connects to the main lighting circuit. When individual LEDs fail or the assembly's driver circuit fails, sections of the interior go dark. This is an OEM replacement manufactured to GE's original specifications.
