LG Microwave Oven Glass Tray

The LG Microwave Oven Rotating Glass Turntable Tray (Part Number: 3390W1A029A) is an authentic original equipment manufacturer (OEM) replacement rotating base designed for select LG solo, grill, and convection microwave ovens. Positioned inside the cooking cavity on top of the rotating roller ring, this heavy-duty tempered glass platter ensures even heat and microwave energy distribution by rotating dishes smoothly throughout the cooking cycle. Its precision 340 mm (34 cm) diameter, 18 mm overall profile, and molded 3-prong center drive hub ensure a secure, slip-free interlock with the turntable motor coupler.

Key Features

• Heavy-Duty Heat-Resistant Tempered Glass: High-thermal-shock-resistant tempered glass engineered to handle extreme cooking temperatures without cracking or warping.

• Precision 3-Lug Drive Hub: Molded bottom clover indentation locks firmly onto standard 3-part drive couplers to prevent slipping during rotation.

• Smooth Textured Food-Safe Surface: Non-porous, stain-resistant, and odor-free surface cleans easily and safely supports heavy dinner plates, casseroles, and microwave cookware.

• Raised Retention Rim: Slight perimeter lip helps contain minor liquid drips and spills inside the tray area.

Benefits

• Solves cracked, chipped, shattered, or missing microwave turntable plates.

• Eliminates jerky rotation or slipping caused by worn center drive grooves.

• Direct OEM replacement ensures perfect 340 mm cavity clearance and effortless rotation on factory roller rings.
