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.

Part #DE74-20016A
The cooking tray can also be known as a turntable tray. This tray is made of clear glass, with an outer diameter measuring approximately 13 and 1/2 inches. The tray comes with 3 round glass feet that are 1/4 inch high, to keep it stable and level when turning. The function of the cooking tray is to ensure food is cooked evenly. The most common reason for needing to replace this part is if your old model has been cracked or damaged. Small chips can expand or spider into larger cracks over time. This part should fit most Samsung microwaves, but check the model number of your unit to see if this tray fits.

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.

First I read through the customer comments, reviews, questions, etc. at Parts Select, which is always a good bet. Then I put "samsung microwave door switch replacement" into youtube and watched some videos. They don't even have to be for Samsung. From what I can tell, many of the appliance companies use the same design and the same jun k parts, so watching a GE video is almost the same for example. Watch some videos to familiarize yourself with the steps. There are maybe six to disassemble and install the new part. I replaced all three switches. They are not expensive and to replace 3 is only 5% more work than to replace just one; you have to take the microwave apart in either case. UNPLUG THE MICROWAVE FROM THE WALL. Start taking it apart. I use my phone to take a picture of any thing I remove, unscrew or disconnect, especially wires, BEFORE I disconnect them. Thee pictures serve as a reference when I go to reconnect and reassemble. If I am uncertain then I check the picture. Good luck!

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.
