The rotating system of your microwave is made up of the motor, roller support, tray carrier and glass tray.
Its role is important, because it allows the waves to be distributed over all the food, for even cooking. The first check to make is to make sure that the “tray stop” button, which is not present on all microwave models, is not activated.
We will then do several electrical checks on the motor.
A spinning tray in a microwave ensures even heating of food. If the tray is not spinning, it can lead to unevenly cooked or heated food. There are several possible reasons why a microwave tray may stop spinning. Here’s a look at some of these potential issues and solutions.
Faulty Turntable Motor
The turntable motor is responsible for the rotation of the microwave tray. Over time, this motor can burn out or become faulty, leading to a stationary tray.
Solution
If you suspect a faulty turntable motor, the best course of action is to have it inspected and replaced by a professional technician. Replacing the motor can be a complex process that involves dealing with the microwave’s electrical components, which can be hazardous if not done correctly.
Broken or Misaligned Drive Bushing
The drive bushing is a plastic component that connects the turntable motor to the tray. If this bushing is broken, worn out, or misaligned, it can prevent the tray from spinning.
Solution
Inspect the drive bushing for any signs of wear and tear. If it is broken or misaligned, you may need to replace it. Make sure to buy a replacement part that is compatible with your specific microwave model. For complicated cases, it’s recommended to get professional help.
Damaged Turntable Coupler
The turntable coupler is a device that connects the motor to the spinning tray. It could be that the coupler has become worn out, cracked, or damaged, preventing the tray from spinning.
Solution
Examine the coupler for any signs of damage. If it’s damaged, it will need to be replaced. As with the drive bushing, ensure you purchase a compatible replacement part for your specific microwave model.
Broken Glass Tray or Roller Guide
If your microwave’s glass tray or the roller guide (the component the glass tray sits on) is broken, it can prevent the tray from spinning.
Solution
Check these components for signs of damage. Replacement trays and roller guides can be easily purchased online or at a local appliance repair shop. Make sure you get the right size and model for your microwave.
Incorrect Assembly
Sometimes, the tray may not spin simply because the assembly of the turntable system is incorrect.
Solution
Ensure the glass tray is seated correctly on the roller guide, and the guide is properly aligned with the drive bushing. Refer to your microwave’s manual for specific instructions.
In conclusion, a non-spinning microwave tray could be due to a variety of issues, from a faulty motor to a damaged coupler, or even incorrect assembly. While some issues can be resolved with a simple part replacement, others may require the expertise of a professional appliance repair technician. Always ensure you’re confident and knowledgeable about what you’re doing when attempting to fix an appliance, to avoid causing further damage or potential injury.
