What causes a microwave to stop rotating?
The primary reason a microwave may stop rotating is due to a malfunctioning turntable motor. This motor is responsible for powering the rotating plate inside the microwave, and if it becomes faulty or damaged, the turntable will not move. Additionally, any blockages or debris that hinder the motor’s operation can also prevent the microwave from rotating properly.
Another potential cause for the lack of rotation could be an issue with the microwave’s control board or the rotation switch. If the control board is malfunctioning, it may not send the necessary signals to activate the turntable motor. Issues with the rotation switch can also disrupt the connection, preventing the turntable from turning even when the microwave itself is functioning correctly.
How can I troubleshoot a non-rotating microwave?
To troubleshoot a microwave that isn’t rotating, start by checking if the turntable is seated correctly on the support ring. Sometimes, the turntable may be misaligned or stuck, which can easily be resolved by lifting it off and placing it back properly.
