    Common microwave repair parts you may need

    Replacing one of these microwave parts may fix your problem.

    Door Hinge Replacement

    If a microwave door hinge becomes bent or breaks, the door may not close correctly, and the microwave probably won't start. Using the microwave with a bent or damaged door hinge is unsafe because radiation might leak through the door if it isn't properly closed or aligned. It's important to have a Sears Home Services professional inspect and repair the microwave whenever a door hinge or the door itself is damaged. After the repair, the technician will need to check for radiation leakage.

    Switch Replacement

    If a switch in a microwave is broken, it can cause various problems, mainly affecting the power to the microwave's components. Microwaves are equipped with several internal thermal switches and interlock switches to ensure your safety if components inside the microwave stop working. Door interlock switches prevent the microwave from running when the door is open to prevent exposure to harmful radiation. Many microwaves also have a magnetron thermal switch that trips if it detects high current or temperature in the magnetron area of the microwave cavity. Another thermal switch monitors the cooking cavity's temperature and trips if it becomes too high. If any of these switches fail, the microwave won't start, and its lights, fans, and display will not work. Because microwaves contain high-voltage transformers and capacitors that can hold dangerous electricity even when unplugged, it's important to have a Sears Home Services professional inspect the microwave and perform any necessary repairs.

    Power Supply Board Replacement

    If the power supply board isn't working, the microwave won't turn on. You'll notice that it won't heat up, the door might not close properly, and the lights, fans, and control panel won't function. This happens because the power supply in a microwave connects the electricity from your home to the microwave's internal components. A faulty power supply might also not protect the microwave from power surges, which could damage electronic parts like the main control board. If your microwave isn't turning on, it's best to have a Sears Home Services professional check it out and replace the power supply board if needed.

    What to expect when you experience a microwave door not closing issue

    How to fix a microwave door not closing problem

    Fixing most issues with doors not closing typically requires replacing the door hinge, switch, or power supply. However, because there are numerous potential causes, conducting a thorough diagnosis is crucial for resolving the problem. An accurate diagnosis is essential for understanding the extent of the repair needed.

    Sears Home Services solutions for a microwave door that is not closing

    If the microwave door isn't closing, there could be various reasons why. To prevent replacing parts that aren't necessary, we suggest having a Sears Home Services professional conduct diagnostic tests to find out what's causing the problem. Our technicians have a lot of experience in figuring out all sorts of issues with microwaves.

    What to watch for with a microwave door not closing diagnosis

    Identifying issues with modern appliances can be challenging without the right knowledge and training. Trying to fix a microwave problem without using proper diagnostic techniques often leads to replacing parts without certainty. Appliances, particularly those developed in the last decade, have become highly sophisticated, with electronic components that are tricky to assess. As a result, DIY repairs on the latest appliance models are becoming more complicated.
