The Plate Bottom is an OEM part for GE microwave ovens. It forms the base surface area that internal microwave components are securely mounted and attached to. 

Causes of failure include warping and cracking of the metal shelf from prolonged exposure to high temperatures.  

Symptoms of a bad plate bottom include:

• Visible distortions or cracks in the metal material  
• Loose mounting locations for interior assembly parts
• Air gaps impairing heat dissipation from components  
• Eventual failure of attached parts over long term use

This OEM GE replacement is also compatible with Hotpoint, RCA and select Kenmore microwave models.

This mount is a replacement support bracket that secures internal components and helps keep assemblies aligned for reliable operation. Replacing a damaged mount restores proper fit and reduces vibration and noise from loose parts. What it does:

• Secures and supports appliance panels or internal assemblies to maintain proper alignment
• Prevents movement that can cause rattling, vibration, or uneven operation
• Helps ensure connected components stay in the correct position for normal function
• Commonly used when mounts are cracked, bent, or missing

• Disconnect power (and water if applicable) before starting any repair
• Use basic hand tools; inspect surrounding fasteners and replace if damaged

• Provides steady drive to the tray via the center coupler
• Typical fix for a non-spinning or intermittently spinning turntable
• Can address loud humming or grinding noises from beneath the oven floor

• Disconnect power before servicing; microwaves contain high-voltage components
• Access is typically from the bottom by removing the motor cover or base panel
• Note wire orientation; transfer connectors, align the shaft with the coupler, and secure with the original screws
• After reassembly, place a microwave-safe cup of water on the tray and run briefly to ensure the turntable rotates
