When to Change a Refrigerator Water Filter

Use time, rated gallons, flow, taste, odor and inactivity as service signals.

Identify the appliance

Photograph the full model label and current cartridge code. Small suffix differences can change compatibility.

Confirm the relationship in a manufacturer record or compatibility chart. Do not rely on shape or marketplace titles alone.

Housing location, reset sequence, flushing quantity and bypass requirements can vary by refrigerator model.

Never force a cartridge. Stop for persistent leakage, no water flow, damaged seals or a filter that will not lock normally.
