BS Turntable Motor Replacement Guide

If your Toshiba EM131A5C-BS microwave turntable is not rotating, the motor has likely burned out. The turntable motor rotates the glass plate to ensure even heating. Replacing it is a MODERATE difficulty repair that requires accessing the bottom of the microwave.

Symptoms of Turntable Motor Failure

Common signs that indicate turntable motor failure:

  • Turntable doesn’t rotate at all
  • Turntable starts then stops
  • Grinding or humming noise from the bottom
  • Motor feels hot to the touch
  • Visible damage or burning smell from motor
  • Uneven heating due to non-rotating turntable

⚠️ Safety Warning

Always unplug the microwave before beginning any repair. Wait 60 seconds after unplugging to allow capacitors to discharge. The turntable motor area is at the bottom of the microwave and is generally low-voltage, but safety precautions are still essential.

Parts Needed

  • Toshiba EM131A5C-BS Turntable Motor (Part number varies by production date – check service manual or model number)

Note: Toshiba may use different motor part numbers depending on production date. Check your model’s service manual or use the model number to find the correct replacement.

Tools Required

  • Phillips Screwdriver – #2 size
  • Needle-Nose Pliers – For wire connections
  • Flashlight – To see under the microwave
  • Clean cloth – For cleaning the motor area

Step-by-Step Instructions

Step 1: Unplug and Prepare

Unplug the microwave from the wall outlet. Remove the glass turntable plate and the roller ring from inside the microwave. Set them aside in a safe location. Turn the microwave upside down or on its side to access the bottom panel.

Step 2: Remove the Bottom Panel

Locate the screws securing the bottom panel. There are typically 4-6 screws around the perimeter. Remove all screws using your Phillips screwdriver. Some models may have clips in addition to screws. Gently lift the bottom panel away to expose the turntable motor area.

Step 3: Locate the Turntable Motor

The turntable motor is located in the center of the bottom area. It’s a small motor with a shaft that extends up through the bottom of the microwave. The motor has wire connections and is typically mounted with screws or clips.

Step 4: Inspect the Motor

Before removing, inspect the motor:

  • Check for visible damage, burning, or overheating
  • Look for loose wires or damaged connectors
  • Inspect the motor shaft for damage
  • Check the coupling between motor and roller ring
  • Verify the motor is the problem (not the roller ring or support)

Step 5: Disconnect the Motor Wires

The turntable motor has wire connections. Use needle-nose pliers to gently pull the wire connectors off the motor terminals. Take a photo before disconnecting to ensure proper reconnection. The wires are typically color-coded.

Step 6: Remove the Motor Mounting Hardware

The motor is secured with screws or clips. Remove the mounting screws using your Phillips screwdriver. Some motors may have a bracket that needs to be removed. Carefully remove all mounting hardware and set it aside.

Step 7: Remove the Old Motor

Once all mounting hardware is removed, gently pull the motor away from its mounting location. The motor shaft extends through the bottom, so you may need to pull it down carefully. Remove the old motor completely.

Step 8: Clean the Motor Area

While the motor is removed, clean the motor area:

  • Remove any debris, grease, or food particles
  • Clean the area where the new motor will mount
  • Wipe down the motor shaft opening
  • Ensure the area is dry before installing the new motor

Step 9: Install the New Motor

Position the new turntable motor in the same location as the old one. Ensure the motor shaft extends properly through the bottom opening. The motor should sit flush against the mounting surface. Secure it with the mounting screws, being careful not to overtighten.

Step 10: Reconnect the Wires

Refer to your photo and reconnect the wires to the new motor terminals. Push the connectors firmly onto the terminals until they click into place. Ensure all connections are secure.

Step 11: Reinstall the Roller Ring and Plate

Turn the microwave right-side up. Place the roller ring in the bottom of the cavity (it sits on the motor shaft or support). Then place the glass turntable plate on top of the roller ring. Ensure everything sits level.

Step 12: Test the Installation

Plug the microwave back into the wall outlet. Place a cup of water in the center of the turntable. Start a 30-second cooking cycle. Watch to ensure:

  • The turntable rotates smoothly
  • No grinding or unusual noises
  • The turntable remains level during rotation
  • Rotation is steady and consistent

Troubleshooting

If the turntable still doesn’t rotate after replacement:

  • Verify wire connections are secure
  • Check the roller ring for damage (may also need replacement)
  • Inspect the turntable support (may be damaged)
  • Ensure the motor shaft is properly aligned
  • Check for obstructions preventing rotation
  • Verify you have the correct motor for your model

Finding the Correct Part Number

Toshiba turntable motors may vary by production date:

  • Check the model number and serial number
  • Consult the service manual for your specific model
  • Contact Toshiba customer service with your model number
  • Search online parts suppliers using your model number
  • Take photos of the old motor to help identify the replacement

When to Call a Professional

Consider professional help if:

  • Multiple components need replacement
  • The problem persists after replacement
  • You’re not confident in your ability to properly install the motor
