MJS63771903 Genuine Microwave Turntable Glass Tray for LG Microwave Ovens, Also Listed as MJS63771901 LG Glass Plate

MJS63771903 is a genuine LG glass turntable tray for LG microwave ovens. It's linked to MJS63771901, so if your manual or old tray shows either number, this is the one. LG makes trays in several diameters with different underside patterns to suit the roller ring and drive coupler. Measure your old tray or check its number before ordering, as no model list is held on file.

Replacing a cracked LG microwave turntable plate

The glass tray sits on the roller ring and locks onto the drive coupler in the centre of the cavity floor. As the motor turns the coupler, the tray rotates so food heats evenly. Trays crack from sudden temperature changes, like a hot tray rinsed under cold water, or break when dropped. A chipped or cracked tray should be replaced, and a tray that doesn't match the coupler may wobble, click or stop turning, leaving cold spots in your food.

Putting the new tray in

Unplug the microwave or switch it off at the wall. Wipe the cavity floor and the roller ring, then seat the ring in its track. Lower the tray so the moulded shape on its underside locks onto the coupler, and turn it by hand to check it sits flat. Run the microwave for a few seconds with a cup of water to confirm it rotates smoothly.
