    Most common repairs needed to fix a Samsung microwave

    Door Hinge Replacement

    When a microwave door hinge is bent or if it breaks, the door won’t close properly and the microwave likely won’t start. Operating the microwave with a bent or damaged door hinge is dangerous. Radiation can leak through the door when it isn’t closed or aligned properly. A Sears Home Services professional should examine and repair the microwave anytime a door hinge or the door itself is damaged. The technician will need to check for radiation leakage after the repair.


    Switch Replacement

    A broken switch in a microwave will cause a variety of issues, mainly with power to the components of the microwave. Microwaves have several internal thermal switches and interlock switches that protect you when components inside the microwave fail. Door interlock switches prevent the microwave from running when the door is open so you aren’t exposed to harmful radiation. Many microwaves have a magnetron thermal switch that trips when it detects high current going to the magnetron or high temperature in that area of the microwave cavity. Another thermal switch monitors the temperature of the cooking cavity and trips when high temperatures occur. If any of these switches fail, the microwave won’t start, lights and fans will be inoperative and the display will be blank. Because microwaves contain a high-voltage transformer and high-voltage capacitors that retain a lethal amount of electricity even with the microwave unplugged, a Sears Home Services professional should examine the microwave and perform the repair.

    Power Supply Board Replacement

    If the power supply board is inoperative, the microwave will not power up. The microwave will not heat, the door may not latch properly, and the lights, fans and control panel won’t come on. This is because the power supply in a microwave connects the incoming power from your home’s electrical supply to the components inside the microwave. A defective power supply may also fail to protect the microwave from power surges, potentially causing damage to electronic components like the main control board. If your microwave is not powering up, have a Sears Home Services professional inspect it and replace the power supply board if necessary.

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

    How is the door not closing problem fixed?

    Correcting most door not closing problems usually involves replacing the door hinge, switch or power supply. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.

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

    When the microwave door is not closing it can be for many reasons. To avoid replacing unneeded parts we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of microwave failures.

    What to look out for with a microwave door not closing diagnosis

    Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your microwave problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.
