The Vent Grille is an OEM part for GE microwaves. This grille is mounted on the exterior of the microwave, typically above the door, and serves as a protective cover for the ventilation system. It allows air to flow into and out of the microwave. Causes of damage to the Vent Grille often involve accidental impacts, such as hitting the grille with kitchen utensils or other objects, or natural degradation from heat and grease exposure over time.  Symptoms of a bad Vent Grille include: Cracks, breaks, or significant wear on the grille, which can compromise its ability to protect the microwave's ventilation system. Looseness or detachment from the microwave, potentially obstructing proper airflow and affecting the appliance's cooling efficiency. Visible signs of discoloration or damage, which could detract from the microwave's appearance. This OEM GE part is also compatible with Hotpoint, RCA, and some Kenmore models.WB07X10967 (AP3883300) replaces 1166639, AH1020368, EA1020368, PS1020368, WB07X10697.
