Micro Door Switch – Part Number: 3405-001034

Micro Door Switch
★★★★★

(12)
Part #3405-001034
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. 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. To confirm that the door switch is faulty, use a multimeter to test for electrical failure. To remove the faulty switch, disconnect the wiring connectors and take note of where they are positioned. Place the new switch in position and reattach the wiring connectors to the appropriate terminals and close the microwave door to check that the switch engages appropriately.

High-Voltage Diode

Part #DE91-70063D
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 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.

Door Switch Lever
Part #DE66-00088B
A microwave that does not sense a closed door may have a bent or broken switch lever. The lever helps press the safety switch when the door latch enters the housing. First check the latch hooks, door fit, switches, and plastic mounts for damage. Match the lever to the complete microwave model and make sure the switch is not also faulty. Unplugging the unit does not remove the high-voltage danger inside. Use trained service for repairs behind the control panel or outer cover. Do not test the microwave with any panel removed or any door switch bypassed.

Removed control panel, discharged HV capacitor. Removed old diode, tested to confirm failure. Replaced part. Other than the removal of the panel swapping the part was almost as easy as replacing a light bulb.

Microwave stopped working - would not heat up

I removed the outer cover and exposed the inner workings. I watched a video on partselect.com to show how to remove and replace the Diode. I followed the instructions and it was very easy to replace.

Unfortunately, the diode was only part of the issue. I ended up replacing the High Voltage capacitor and Magnetron also. Those w ere a little more complicated but still easy to do.

Now the Microwave works just like new! Cost me less than $100 for all parts.

Appears to work, but food not heated

The high voltage tired was shorted. I replaced it with a new one, but that did not solve the problem.

You can test the high voltage tired with a voltmeter and a 9 V battery. Search Search for it on YouTube.

You can also test the high voltage capacitor, the high-voltage transformer, and the magnetron with a multi met er. Search for the procedures on YouTube.

I tested all these high-voltage components with a low-voltage multi meter, and they all checked out OK (after replacing the diode). However the microwave still did not heat food.

When working on a microwave it is important to unplug it and also discharge the high voltage capacitor. The capacitor has a 10 megaohm resister to automatically discharge itself, but it may have failed – – so discharge it manually.

In the end I ordered a new microwave.
