The Glass Tray is an OEM part for Whirlpool built-in microwaves. This heat-resistant glass plate helps distribute incoming microwave energy evenly throughout cooking cycles. 

Causes include normal thermal stress cracks from rapidly changing microwave temperatures daily. Accidental impact damage is also possible if rack assemblies are mishandled.

Symptoms of a problematic glass tray include:

• Inconsistent or inadequate microwaving of certain foods
• Hotter or cooler areas noticed depending on placement
• Visible corrosion, cracks or pitting of the tray surface over time
• Sparking, arcing or strange noises from inside the microwave cavity

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

The Ring-Turn is an OEM part for Whirlpool microwaves. Designed with precision, this component plays a crucial role in the microwave's turntable system, supporting the glass plate and ensuring it rotates smoothly during operation. The ring-turn's seamless integration with the microwave design allows for the even distribution of microwave energy, which is essential for consistent cooking and heating results.

Causes of a bad Turntable Ring can include cracks or breaks developing from years of use rotating the turntable back and forth under high heat levels.  

Symptoms of a bad Ring-Turn include:

• The microwave turntable not rotating properly
• Unusual noises during operation, indicating a misalignment or damage
• The glass plate not sitting flat or slipping during use
• Uneven or partially cooked food, resulting from improper rotation

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

Causes of a bad coupler can include wear and tear from regular use, accidental damage from heavy items placed on the turntable, or misalignment issues. A malfunctioning coupler can lead to uneven cooking and potential damage to the microwave’s internal components.

Symptoms of a bad microwave coupler include:

• The turntable not rotating
• Uneven cooking or heating of food
• Grinding or clicking noises during operation
• The turntable tray wobbling or not staying in place

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
