Gemroom 12" Microwave Glass Plate Replacement for Whirlpool - Borosilicate, Dishwasher-Safe

Gemroom's 12" borosilicate microwave glass plate is a direct-fit replacement engineered to match common Whirlpool and major-brand turntable hardware while offering durable, food-safe performance.

If your microwave's original glass tray is cracked, missing, or wobbly, this 12-inch replacement from Gemroom restores stable, even rotation and safe heat handling. Manufactured from heavy-duty borosilicate, the plate is lead-free, dishwasher-safe, and designed to resist thermal shock so you can re-use your existing roller ring and coupler without guesswork.

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

Measure both the diameter and the under-plate hardware to ensure compatibility. Even without the original plate, a simple two-step measurement and hardware inspection will tell you whether the Gemroom plate matches your appliance.

• Measure distance from drive coupler center to interior door edge: Required diameter ≈ (measured × 2) - 1".
• Check the plate bottom for track ID (7 5/8") and track OD (10 1/4").
• Confirm coupler type: small-size fit for this model.
• Cross-reference OEM part numbers listed in the product details for quick verification.
