Overview

The LG 3390W1A044B is a genuine OEM replacement turntable tray designed to restore full, even cooking performance to compatible LG microwave models. When the original glass tray chips, cracks, or breaks — which happens more often than most people expect given daily thermal cycling — the microwave doesn't stop working, but food starts cooking unevenly as the rotation is disrupted or the tray is removed entirely. This replacement puts the oven back to factory spec: the same glass thickness, the same 12-inch diameter, the same coupler hub that mates with the drive mechanism below.

Installation is straightforward — remove the roller ring, set it in place, lower the tray onto it, and the microwave is ready to use. The clear glass construction makes it easy to clean after spills, and it handles normal microwave temperatures without issue. The critical step is compatibility verification: this tray fits a defined range of LG models, and using the microwave's model number (found on the door frame sticker) to confirm the match before ordering prevents the most common return scenario. For anyone dealing with a broken OEM tray, this is a clean, no-compromise fix.

Pros & Cons

👍 Pros

  • Genuine OEM manufacturing ensures the tray seats correctly on the coupler and roller ring without wobble or off-center rotation.
  • Clear glass construction allows you to monitor food without removing the tray, and cleans easily after spills.
  • Restores even cooking performance — a worn, cracked, or broken tray causes uneven heat distribution that a replacement fixes immediately.
  • Exact 12-inch diameter means no trimming or adapting required for compatible LG models.

👎 Cons

  • Compatibility is model-specific — without confirming your microwave's model number first, there's a real chance of ordering the wrong size or hub type.
  • Does not include the roller ring, so if both parts are damaged, a second order is required.
  • Glass construction means it's still vulnerable to thermal shock — placing a frozen dish directly on a cold tray and microwaving immediately can crack it over time.
  • Limited model compatibility means this won't work as a universal replacement across different microwave brands or even all LG models.

Frequently Asked Questions

Start with your microwave's model number — cross-reference it against LG's compatibility list for part 3390W1A044B. The tray is 12 inches in diameter, which fits a specific range of LG models. Check your owner's manual or the model number sticker inside the microwave door frame before ordering.
This is a genuine OEM part manufactured by LG to the same specifications as the original tray. That means exact dimensions, glass thickness, and coupler hub geometry — all of which affect how smoothly the tray rotates on the roller ring.
It's made of clear tempered glass designed specifically for microwave use — rated for the heat, humidity, and microwave energy exposure inside the oven cavity.
Just the glass turntable tray. The roller ring (the plastic wheel assembly the tray sits on) is a separate part. If your roller ring is worn or cracked, order that separately by checking the part number for your specific model.
LG OEM glass turntable trays are generally dishwasher-safe, but confirm with your microwave's owner's manual for cleaning recommendations specific to your model.
