Reasons Your Microwave Is Making a Banging Noise
- The turntable isn’t installed correctly – A common cause of banging noises is that the microwave turntable isn’t sitting properly on the support or coupler. If you want to check whether this is the case, just turn off the turntable and see if the noise disappears.
- The support rollers are not operating properly – Sometimes, the issue isn’t strictly the microwave turntable but the support rollers under it. This can happen when there are small food particles left in the microwave and caught on the rollers.
Steps to Fix a Thumping Microwave
- Open the microwave.
- Remove the turntable.
- Remove the turntable support.
- Clean all the parts thoroughly, including the rollers on the support.
- Replace the turntable support.
- Put the turntable back on the support, making sure to align it with the coupler in the middle.
There you have it! Now, let’s verify whether you’ve managed to solve the banging noise. You can do this by following these steps:
- Plug in the microwave.
- Put one cup of water on the turntable (make sure to use a microwave-safe cup).
- Turn on the microwave for a minute.

On the other hand, sometimes you may need to replace a part, which may or may not cost less than buying a new microwave (depending on the part and the quality of the new microwave). If your microwave is from the Whirlpool family of products you can check Whirlpool Parts for your required components.
