Microwave Not Turning

Microwaves are a convenient and essential kitchen appliance in many households. However, like any appliance, they can develop issues over time. One of the most common problems is a microwave turntable that’s not turning. This can be incredibly frustrating, especially when you’re in a hurry. In this blog post, we will discuss the possible reasons why your microwave turntable isn’t turning and provide step-by-step instructions on how to fix it.

If you need to test an electrical component when making your repairs, more often than not, you will need a multimeter. You can pick one up here on Amazon.

Possible Causes and Solutions

1. Microwave Not Turning: Drive Motor

If the turntable on your microwave doesn’t rotate or is making a grinding noise, the problem may be with the drive motor. Most microwave ovens with a round glass tray use a motor-driven coupler to turn the tray or a roller guide¹.

How to Fix: The motor is typically located below the floor of the oven, and access will need to be through the bottom. The motor is normally held in place with a retaining screw and will have two wires attached to it as well. If the motor is making a grinding noise it will need to be replaced. If the motor doesn’t turn, you can check for voltage or continuity with a multimeter.

With the power disconnected and the bottom panel removed, locate the motor and unplug the wires to the motor. Measure for continuity at the motor terminals or at the wire harness that is still attached to the motor. If there is no continuity, the motor will need to be replaced.

2. Microwave Not Turning: Coupler

If the turntable on your microwave doesn’t rotate, the problem may be with the drive coupler. Most microwave ovens with a round glass tray use a motor-driven coupler to turn the tray on a roller guide.

How to Fix: Remove the tray and roller guide from the oven and then inspect the coupler. Most models will have a three-sided coupler that will just pull off of the motor shaft. Some models may require that you remove the motor from the bottom before you can pull the coupler off of the motor.

The coupler normally has a D-shaped opening that fits tightly onto the motor shaft and if it is cracked or worn it will need to be replaced. If you have to remove the bottom cover, you will need to disconnect the power from the appliance first.

3. Microwave Not Turning: Roller Guide

If the turntable on your microwave doesn’t rotate, the problem may be with the roller guide under the tray. Some microwave ovens with a round glass tray use a motor-driven coupler to turn the roller guide that the tray rests on.

How to Fix: Remove the tray and then inspect the roller guide. Check the hub to see if it engages the coupler securely and also the outer rollers for signs of cracks or damage. If there are signs of wear or damage, it should be replaced. If the roller guide appears to be normal, then check the coupler for damage.

In conclusion, if your microwave turntable isn’t turning, it could be due to a number of issues, from a faulty drive motor to a problem with the coupler or roller guide. By understanding these common problems and how to troubleshoot them, you can keep your microwave in good working order.

Note:

Repairing a microwave at home can pose significant dangers if not approached with caution and expertise. Microwaves are complex appliances that operate on high voltages and contain potentially lethal electrical components. Opening up a microwave without proper knowledge and training can expose individuals to the risk of electric shock or severe burns. Additionally, microwaves emit harmful radiation, and tampering with the internal shielding can lead to exposure to dangerous levels. Moreover, improper handling or incorrect reassembly of the microwave can result in fire hazards, as microwaves generate heat to cook food.
