Learn Why Your Microwave Turntable Is Not Working
The microwave is one of the most practical kitchen appliances in any household. But because it’s incredibly useful, it can ruin your kitchen routine if it has even a small issue. It can make things difficult when you encounter various problems with the appliance, including the microwave turntable not working.
The turntable is the flat surface inside the microwave where you place the kitchen utensils when heating things. It has to move so the food can be heated evenly, which makes it a significant issue if it isn’t working or turning. We’re here to discuss the common causes and solutions to various microwave turntable issues.

Common Causes of a Microwave Turntable Not Working
Is your microwave turntable not turning smoothly? There are various possible reasons why that is. It could be due to a failing motor, damaged coupler, faulty turntable guide, misaligned tray, or broken support wheels. Whatever the reasons behind a microwave turntable not working, it will undoubtedly affect the appliance’s performance. This makes it crucial to know the following common causes of microwave turntables not working:
Turntable Motor Failure
Why does my microwave turntable not turn? One of the possible reasons is turntable motor failure. If the motor fails, the turntable will not spin. A motor failure can be due to various reasons, such as overheating, lack of lubrication, or a manufacturing defect. In most cases, you will need to replace the motor to fix the issue.
Damaged Turntable Coupler
If your over-the-range microwave turntable is malfunctioning, one of the possible causes is a damaged turntable coupler. It’s a component connecting the motor to the turntable. If the coupler is broken or damaged, it makes sense that the turntable won’t spin. A damaged coupler can happen due to wear and tear, improper use, or a manufacturing defect.
Malfunctioning Turntable Guide
The turntable guide is the part of the microwave that keeps the turntable in place, preventing it from wobbling. The turntable may not rotate properly if the guide is damaged or malfunctioning, likely due to wear and tear, improper use, or a manufacturing defect. In most cases, you can fix the turntable problem by replacing the guide.

Misaligned Turntable Tray
You’re wondering, “Why won’t my microwave turntable turn?” The answer could be that its turntable tray is misaligned. The turntable rotates smoothly on its support guides or rollers to heat food evenly. If it’s not properly seated, the rotation becomes uneven or wobbly. This can cause the turntable motor to shut off and the turntable to stop turning.
Broken or Worn-Out Support Wheels
The support wheels are small rollers on which the turntable tray rests. The turntable will not rotate smoothly if these wheels are broken or worn out. A worn-out or broken support wheel can be caused by wear and tear or a manufacturing defect. Fortunately, it’s not complicated to repair since the technician only needs to replace them to fix the problem.
Faulty Door Switch
Some microwaves have a door switch that prevents the turntable from spinning when the door is open. So, a microwave turntable not turning could be due to a faulty door switch. If you suspect that the cause of your turntable not working is the door switch, you can fix the issue by having the switch checked and replaced by a qualified technician.

Control Board Malfunction
The control board is the component that regulates the functions of the microwave. It stands to reason that if it’s malfunctioning, it can cause the turntable to stop turning. If this is the case with your microwave, you can try resetting the device first. If it doesn’t work, you might have to replace the control board to fix the problem.
Power Supply Issues
You want to know the answer to, “Why did my microwave turntable stop turning?” It might be that it didn’t receive sufficient power. Check that the microwave is properly plugged in and the circuit breaker is not tripped. Once these issues are ruled out, the likely culprit of a microwave turntable not working is an electrical problem.

How to Fix a Microwave Turntable Not Turning
1. Perform Basic Checks
Perform basic checks like checking the turntable and its support wheels, ensuring there aren’t any obstructions causing it to stop spinning. Also, make sure that the turntable plate is right side up. Don’t forget to check if your microwave has a turntable off option, checking to make sure it’s not selected. Last but not least, make sure that latches and doors close properly.
2. Clean the Microwave
Cleaning the microwave is also essential. Remove any dirt or food buildup, which might disrupt the appliance’s work. General grime and sticky messes can stop the turntable from spinning. By cleaning your microwave regularly, you can reduce the chances of issues developing, including a microwave turntable not working.
3. Repair or Replace Faulty Parts
The next step is to find and fix the problem’s cause. Consult the list of possible causes mentioned above to diagnose the issue. You might have to do this one by one until you find the root cause, and when you do, you’ll have to either repair it or replace the faulty part. In most cases, you need to switch a component with a brand new one.
4. Call an Appliance Repair Technician
Did DIY not work? In that case, it’s best to call a qualified appliance repair technician. They have the knowledge and expertise to properly diagnose and repair a microwave turntable not working. Besides expert repair, they have warranties and other benefits you can take advantage of. A professional appliance repair service can repair your microwave properly the first time, saving you time, cost, and effort.
Can I use my microwave without the turntable?
Technically, you can use a microwave without the turntable, but it’s not recommended. The turntable helps distribute the microwaves evenly and ensures the food cooks evenly. Without it, the food may cook unevenly. Some areas of the food may become overcooked while others remain undercooked.
How do I clean the microwave turntable?
Cleaning the microwave table entails removing it from the microwave and washing it with warm, soapy water. You can also put it in the dishwasher if it is dishwasher-safe. Ensure that you dry it thoroughly before putting it back in the microwave.
How do I know if my microwave turntable motor is bad?
The turntable may not spin at all or may turn slowly or intermittently if the microwave turntable motor is bad. You may also hear unusual noises coming from the microwave. If you suspect the motor is bad, consult the manufacturer’s instructions or a qualified technician for assistance with replacing the motor.
Can a burned-out light bulb cause the turntable to stop working?
The light bulb and turntable are two unrelated components of the microwave. They don’t directly affect each other, so a burned-out light bulb is unlikely to cause a turntable to stop working.
How do I know if the roller guide or drive couple is the problem with a microwave turntable not working?
You can determine this by inspecting the appliance. First, unplug the microwave and remove the turntable and support guide. Next, check the roller guide and drive coupling for signs of wear and tear or damage, such as cracks and misalignment. If either of the two components is damaged, you will have to replace it.
