The Light Lens Shield is an OEM component for GE refrigerators. As a cover installed behind the door light source, it protects sensitive refrigerator components. This shield measures about 16 inches wide by 5 inches high. Normal wear occurs due to regular door opening/closing cycles inevitably generating friction over many years. Excessive impact from heavy load placements could potentially crack rigid plastic covers as well. Symptoms of a damaged or defective light lens shield include:  Gaps exposing electrical wiring to potential spills Loose fit unable to block light leakage from peeping behind Signs of stress fractures or cracks in the protective covering Discolored stains or residue buildup along plastic edges This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.WR17X12486 (AP4419828) replaces 1477332, AH2354534, EA2354534, PS2354534.
