Gemroom 12" Microwave Glass Turntable Plate Replacement for Whirlpool - 12in Borosilicate, Small Coupler

Gemroom's 12" microwave glass plate is a direct-replacement borosilicate turntable engineered to fit Whirlpool and many major-brand microwaves with the specified track and coupler dimensions.

If your microwave's original turntable is cracked, shattered, or missing, this Gemroom 12-inch replacement plate offers a dependable, lead-free solution built to match common OEM part numbers and under-plate hardware. Manufactured from heavy-duty borosilicate glass, it resists thermal shock, is dishwasher-safe, and is sized to align with a 7 5/8" track ID and a 10 1/4" track OD using a small-type coupler. We designed this product to reduce the confusion that often comes with replacing microwave glass by giving clear sizing specs and compatibility notes so you can order the correct plate the first time.

How do I confirm this 12" plate will fit my microwave?

Verify both the overall diameter and the shape of the drive coupler/roller ring under the plate rather than relying on brand alone. If you still have the old plate, measure straight across; if not, follow our measuring method for accurate results.

• Plate diameter: 12" (measure across the glass edge-to-edge).
• Track ID: 7 5/8" and track OD: 10 1/4"—match these to your roller ring.
• Coupler type: Small size—confirm your microwave's drive hub matches.
• Cross-check OEM part numbers (e.g., W11367904, W11335034) against your model.

Which brands and models is this replacement compatible with?

This Gemroom plate fits over 1,000 microwave models from Whirlpool, GE and other major manufacturers when your measurements and under-plate hardware match the specs listed. Use the part numbers and compatibility list to confirm before purchasing.

• Compatible with OEM references like W10337247, WPW10337247, W11443145.
• Fits many Whirlpool and GE models—check your model number on the full compatibility chart.
• Works with standard small coupler drive systems and common roller-ring arrangements.
• If in doubt, compare both diameter and coupler geometry to avoid returns.

What materials and safety features does this replacement plate include?

The plate is made from premium borosilicate glass that is lead-free and rated for direct food contact. It withstands temperature changes better than ordinary glass, cleans easily in a dishwasher, and avoids odors or stains during normal microwave use.

• High-purity borosilicate construction—thermal-shock resistant.
• Lead-free and tested for direct food contact.
• Dishwasher-safe for straightforward cleanup.
• Durable thickness designed for everyday microwave cycles.

How can I avoid common sizing mistakes when ordering a replacement plate?

Most returns happen because buyers order by brand only or guess measurements. Use our three-step approach—measure diameter, inspect under-plate hardware, and compare to the provided specs and images—to get the right plate on the first try.

• Do not assume the same brand equals the same plate size.
• Use a flat tape measure and follow the 2-step measurement formula if your plate is missing.
• Compare your drive coupler to the "Common Compatible Accessories" image provided.
• Contact our expert sizing help if you are unsure of fit.
