Microwave Turntable Turns When Door Is Open

Microwaves are essential kitchen appliances that have simplified cooking and heating processes. They are equipped with various features, including turntables, which rotate to ensure even heating of food. However, encountering a situation where the microwave turntable turns when the door is open can be concerning and potentially dangerous. In this article, we’ll explore the reasons behind this issue and discuss the necessary steps to address it.

Reasons for the Turntable Turning When the Door Is Open:

  1. Misaligned Door Switches:
    • The microwave door has safety switches that are designed to prevent the oven from operating when the door is open.
    • If one or more of these door switches become misaligned or malfunction, the microwave may mistakenly think the door is closed, allowing it to operate with the door open.
  2. Defective Interlock Switches:
    • Interlock switches are another set of safety mechanisms that work in conjunction with the door switches to prevent the microwave from running when the door is open.
    • If any of these interlock switches are faulty or damaged, they may fail to engage properly, leading to the turntable and microwave functioning with the door ajar.
  3. Control Panel Malfunction:
    • In some cases, the control panel or circuitry responsible for detecting the door’s status may malfunction.
    • This malfunction can result in the microwave not receiving the correct signal that the door is open, causing it to continue running.

Safety Concerns:


Addressing the problem of a microwave turntable turning when the door is open requires diligence and a focus on safety. Regular maintenance, careful use, and prompt attention to issues are key to preventing such problems. If troubleshooting and basic repairs don’t resolve the issue, it’s wise to seek professional assistance to ensure that your microwave operates safely and efficiently. Always prioritize safety when dealing with microwave-related problems to protect yourself and your household.
