What are the common reasons why a microwave turntable stops rotating?
There are several common issues that can cause a microwave turntable to stop rotating. One of the most frequent causes is a misalignment of the turntable. This can occur if the turntable is not seated properly on the turntable shaft or if the shaft itself is faulty. Additionally, debris or food particles can accumulate in the turntable mechanism, preventing it from functioning smoothly.
Another reason could be a malfunctioning motor or drive system. The turntable is powered by a small motor that can wear out or fail over time. In some cases, a blown fuse or electrical issue within the microwave itself may also be responsible. It’s important to inspect each component to identify the root cause before proceeding with repairs.
How can I troubleshoot my microwave’s turntable?
