LG Microwaves Plate Broken: How to Fix It Yourself

A broken turntable plate in your LG microwave is an easy fix — just measure the diameter of the old plate and order a replacement. Universal plates are available if you cannot find a brand-specific one.

⚡ Difficulty: Easy⏱ 15-30 minutes💰 Parts cost: $0-$25🔧 Tools: None needed

⚠️ Safety First

  • Always unplug the appliance from the wall before starting any repair work.
  • Microwaves contain a high-voltage capacitor that can hold a lethal charge even when unplugged. Do not open the microwave cabinet unless you are experienced with appliance repair. The steps below focus on safe, external fixes.

Step-by-Step Repair

  1. 1

    Measure your turntable plate

    Remove the broken plate from your LG microwave. Measure the diameter from edge to edge in inches. This is the most important measurement for finding a replacement. Common sizes are 10.5, 12.4, and 13.5 inches.

  2. 2

    Find the right replacement

    Look for your LG model number (usually on a sticker inside the door or on the back). Search for "LG microwave turntable plate" with your model number. Universal plates work too — just match the diameter and the coupler type (three-pronged or flat bottom).

  3. 3

    Clean while the plate is out

    With the old plate removed, clean the roller ring guide and the floor of the microwave. Wipe up any food or liquid with a damp cloth. This is a great opportunity to deep clean since the plate is already out.

  4. 4

    Install the new plate

    Place the roller ring guide back in position. Set the new plate on the coupler, making sure it sits evenly and rotates freely when you push it gently. It should glide smoothly without catching.

  5. 5

    Test it

    Close the door and run the microwave for 30 seconds with a cup of water inside. The plate should rotate smoothly. Replacement plates for LG microwaves typically cost $10-$25.

If That Didn't Work

  • A faulty control board on your LG microwave could be the root cause, though this is less common.
  • Wiring issues between components — loose or corroded connections — can cause intermittent problems.

When to Call a Professional

If the steps above don't fix your LG microwave, a professional repair technician can diagnose the issue quickly. Most repairs cost $100-$250 including parts and labor. If your microwave is older than 8-10 years, compare the repair estimate to the cost of a new one.
