Title: Bosch Microwave HMV5051U/01 Turntable Not Turning

Have you ever experienced the frustration of your Bosch Microwave HMV5051U/01 turntable not turning? It can be quite perplexing when you’re eagerly waiting for your meal to be heated evenly, only to find that the turntable is stationary. But fear not! In this article, we will explore the possible reasons behind this issue and provide you with some simple troubleshooting steps to get your turntable spinning again. So, let’s dive right in!

1. Understanding the Importance of a Turntable:

Before we jump into troubleshooting, let’s discuss why the turntable is such a crucial component in your Bosch Microwave HMV5051U/01. The turntable ensures that your food is heated evenly by rotating it throughout the cooking process. Without a functioning turntable, you may end up with cold spots in your food, leading to an unpleasant dining experience.

2. Check for Obstructions:

The first step in troubleshooting a non-turning turntable is to check for any obstructions. Sometimes, small objects or food particles can get stuck in the turntable mechanism, preventing it from rotating. Carefully inspect the turntable and the area underneath it for any debris that might be causing the issue. Remove any obstructions and give the turntable a spin to see if it starts working again.

3. Verify the Turntable Drive Coupler:

The turntable drive coupler is a small plastic piece that connects the turntable motor to the turntable tray. Over time, this coupler can wear out or become damaged, resulting in the turntable not turning. To check the coupler, remove the turntable tray and inspect the coupler for any signs of wear or damage. If you notice any issues, you can easily replace the coupler with a new one.

4. Examine the Turntable Motor:

If the turntable drive coupler appears to be in good condition, the next step is to examine the turntable motor. The motor is responsible for powering the rotation of the turntable. Start by unplugging your microwave and removing the cover to access the motor. Inspect the motor for any visible signs of damage or overheating. If you notice any issues, it’s best to contact a professional technician for further assistance.

5. Test the Turntable Motor Capacitor:

The turntable motor capacitor is a component that helps start the motor and keep it running smoothly. If the capacitor is faulty, it can prevent the motor from functioning correctly. To test the capacitor, you will need a multimeter. Set the multimeter to the capacitance setting and touch the probes to the terminals of the capacitor. If the reading is significantly lower than the specified capacitance, it’s time to replace the capacitor.

6. Ensure Proper Alignment of the Turntable:

Sometimes, the turntable may not rotate because it is not properly aligned. Ensure that the turntable is correctly positioned on the turntable support ring. It should sit evenly and not be tilted or off-center. Adjust the position of the turntable if necessary, and test if it starts rotating again.

7. Check the Turntable Drive Motor Coupling:

The turntable drive motor coupling is another crucial component that connects the motor to the turntable. If this coupling becomes loose or damaged, it can cause the turntable to stop turning. Inspect the coupling for any signs of wear or damage. If necessary, replace the coupling to restore proper functionality.

8. Examine the Control Board:

If all the previous steps fail to resolve the issue, it’s time to examine the control board. The control board is responsible for sending signals to the turntable motor, instructing it to rotate. A faulty control board can disrupt this communication and result in a non-turning turntable. However, diagnosing and repairing control board issues can be complex and require professional expertise. It’s recommended to seek professional assistance in such cases.


A non-turning turntable in your Bosch Microwave HMV5051U/01 can be frustrating, but with the right troubleshooting steps, you can resolve the issue and get back to enjoying evenly heated meals. Remember to check for obstructions, inspect the turntable drive coupler and motor, test the motor capacitor, ensure proper alignment, and examine the turntable drive motor coupling. If all else fails, consult a professional technician to diagnose and repair any control board issues. With these tips, you’ll have your turntable spinning again in no time!
