Supco Range Microwave Cooking Tray - MW014A

Supco Range Microwave Cooking Tray - MW014A

Restore proper microwave turntable support with this Supco microwave cooking tray. It replaces a cracked, chipped, missing, or incorrect-size glass tray in compatible microwave models.

MW014A is an aftermarket replacement microwave glass tray for supported Whirlpool and LG microwave platforms. The tray holds cookware and food while rotating on the turntable drive system to help cooking heat more evenly.

Compatibility: Supco lists MW014A as a 12-inch glass tray for Whirlpool and LG models and cross-references Whirlpool W10337247 and LG 3390W1G014A.

This part commonly replaces or cross-references W10337247 and 3390W1G014A.

Fitment / What To Verify: Verify tray diameter, bottom drive-coupler pattern, roller ring size, hub contact points, and the microwave model number. Similar glass trays can be close in diameter but fail to sit correctly on the turntable coupler.

Please confirm fitment with your appliance model number before ordering.

Is it time to replace?

• Common Symptoms: Microwave tray is cracked, chipped, missing, wobbling, not rotating, or too small/large for the turntable ring.
• Visible/Sensory Cues: Broken glass edge, worn bottom drive contact, rocking on the center coupler, or food rotating unevenly because the tray does not sit flat.

Pro Tip: If the replacement tray still does not rotate, inspect the roller ring and turntable motor/coupler before assuming the glass tray is the only failed part.
