Microwave glass turntable plates: GE WB49X10097 vs Whirlpool W10337247 vs Samsung DE74-20102D (and roller rings)

A cracked or shattered microwave glass tray is cheap to replace, but plates are not universal. Two plates of the same diameter can still wobble or jam if the center coupler notches or the roller-ring track underneath don't match. This page helps you read your microwave model, measure three things, and order the right OEM number or a compatible plate that prints it.

Who needs this

• Anyone with a cracked, chipped, or shattered microwave glass tray
• Owners whose tray wobbles, clicks, or doesn't spin (often the roller ring or coupler, not the glass)
• People choosing between dozens of "11.5 inch" and "12 inch" plates on Amazon
• Over-the-range GE, Whirlpool, and Samsung microwave owners

How to choose (model, three measurements)

1. Read the model number on the label inside the door frame or on the back. Look it up on a parts diagram and copy the glass tray (turntable) number.
2. Measure the old plate edge to edge, even if it's broken. 11¼", 11.3" (287 mm), 11½", 12", and 12.4" are all common and not interchangeable.
3. Check the center. Count the notches on the underside (three-notch / Y-type coupler is common) and note whether the center hole is small or large.
4. Measure the track. The raised ring on the underside where the roller ring rides. WB49X10097 has an 8¾" outer track; W10337247 has a 10¼" outer track.
5. Pick the right number.
   • GE WB49X10097 (11¼"): for many GE JEM25 / JEM31 / JES1139 / PEM31 / ZEM200-class countertop and compact models. Genuine on Amazon: B00308NSOO.
   • Whirlpool W10337247 (12"): three-notch 12" plate for many Whirlpool-family microwaves.
   • Samsung DE74-20102D (287 mm): glass tray for many Samsung models; listed on Samsung's own accessory store.
6. Check the roller ring and coupler. If the tray won't turn or wobbles, the ring wheels or the plastic coupler may be the problem. Replacement rings list outer diameter, inner diameter, and wheel height (e.g. 7" OD / 6.5" ID / 14 mm wheels on Amazon B085ZSPM8F). Match all three to the old ring.
7. OEM vs compatible. OEM plates cost about $35 to $80. Compatible borosilicate plates are cheaper; buy only ones that publish diameter, track diameter, and coupler type. PENDING_ASSOCIATES until a Tracking ID is configured.

FAQ

Can I use any plate that's the same size?

No. The center coupler and the underside track also have to match, or the plate won't seat or turn smoothly.

My plate isn't broken but won't spin. What do I replace?

Check the roller ring for flat or missing wheels and the center coupler for cracks first. Those are cheaper than a plate.

Is it safe to use the microwave without the tray?

Follow your manual. Many turntable models expect the tray in place, and food heats unevenly without it.

Are compatible plates OK?

Yes, if the listing gives plate diameter, track diameter, and coupler type that match your old plate or your OEM number.
