This door switch, also known as a safety switch, is a genuine OEM replacement part for microwaves. It is a safety mechanism that sends signals to the microwaves control system, telling it when the door is open/closed. This ensures that the microwave only operates when the door is securely shut and switches off as soon as the door is open....Read more Over time, this switch can become worn out or damaged. A faulty door switch can result in failure to switch the microwave on/off, lack of heat, and running with the door open.

This high-voltage diode is designed for use within various makes and models of microwaves and is a genuine OEM part that converts alternating current (AC) into direct current (DC). If you notice your microwave turns on and starts but does not heat anything, this diode is likely responsible. You can check the continuity of the diode with a...Read more multimeter before outright replacing it, but it is important to remember that doing any repairs on a microwave and dealing with sensitive electrical components should be done carefully and with the appropriate precautions to avoid any hazards. To replace the high-voltage diode in your microwave, disconnect it from power and allow it to discharge. Using the appropriate screwdrivers, gain access to the control panel of the microwave. Using an insulated screwdriver, release any electrical charge in the capacitor by touching it across the terminals. Then you can remove any hardware securing the diode, including the harness connecting it to the capacitor, which may be easiest done with pliers. Connect the new diode to the capacitor terminal and the securing bracket, and then reassemble your microwave before connecting it to power again.
