Filter light came on early for WFCB
Treat the indicator as a service reminder, then inspect actual conditions. The published Frigidaire record identifies this cartridge as PureSource Plus Water Filter.
Start with fit verification
Match the complete refrigerator model and the code printed on the existing cartridge. Frigidaire PureSource Plus filter. Exact refrigerator models are taken from the manufacturer compatibility chart. Do not infer compatibility from color, overall shape or brand alone.
Service baseline
The available record uses 6 months. Water quality, usage and long periods of inactivity may justify earlier service.
Safe action
Follow the refrigerator manual and the 1-2-3 installation sequence; flush as directed. If the cartridge does not seat normally, water does not return after flushing, or the housing leaks, stop and use the refrigerator’s model-specific manual.
Evidence
Open the linked source before purchase. FilterRef separates published compatibility from general troubleshooting guidance and does not treat an aftermarket cross-reference as automatically equivalent.
