Product Description

Black Sleeve Diode Specifications

In your microwave, the diode allows current to flow one-way only, converting alternating current to direct current. If you notice that your microwave does not heat properly, you may need to replace the diode. This product is approximately 3 inches in length. Before completing this repair, be sure to disconnect the power source from the microwave. The diode is located inside the main compartment of the microwave, so you will need to open it up before you can complete this repair. This is an OEM part sourced directly from the manufacturer. Many of our customers have rated this repair as easy.

    Where's is it located, how do I replace it ? Can't seem to find any instructions, thank you
    For model number MMV5000BAW
    Hi Terry, Thank you for the question. The Diode is located next to the capacitor in behind the controls. You will need to remove the cabinet from the microwave to access the Diode.The diode is held in by 2 screws. Be sure to disconnect the power source from the microwave.The microwave can hold a charge even when unplugged so use caution. You can discharge the capacitor,Do this by touching an insulated-handled screw driver to one terminal, then slide it toward the other terminal until it makes contact and hold it there for a few seconds.Repeat the procedure to create a short between each capacitor terminal and chassis ground.Hope this helps!

    Unit operates but does not cook and I also get the smell of an electrical fire. If the problem is the black sleeve diode would it have that smell?
    For model number MVH250E
    Hello Todd, Thank you for the question. I suggest testing the diode with a multi meter to check for continuity. Hope this helps!

    My Amana microwave makes a loud hum and doesn't heat.
    For model number ACO1560AB
    Hi Steven, thank you for your question. There are a couple of parts that you should take a look at. The first part to check would be your diode. If that part is working correctly then it may be your magnetron that is the issue. I hope that helps. Good luck with your repair.

        Sparks and loud hum from oven
        1. I went to the internet to find the service manual for the Maytag microwave.
        2. I opened up the oven and started measuring the resistance of the diode, capacitor, transformer, and magnetron between terminals and then to ground. The transformer and magnetron were well within the resistance limits. The diode was shorted in both directions(+-). The capacitor was fully open in both directions -- high resistance.
        3. I ordered the 2 parts, installed them, and ran the oven. Worked perfect first time.
        4. Reinstalled oven and worked ever since (1 week so far).
        5. The secret was that the transformer had a load hum. I figured the transformer was OK. The magnetron had no short between filaments and ground to filaments. The only two left were the diode and capacitor. The first two are about $200 -- almost the value of a new microwave. The $70 repair was well worth it. If the first two were still bad, then tempted to buy a new oven.

        no heat
        I looked up the #1 reason for no heat for my microwave on the site , and using my model number found that 92% of the time it was the Black Sleeve Diode. Ordered the $15 part, and installed it within 30 minutes. Most of the time was used for removing the built in microwave and removing the cover. Replaced the diode by finding it on the diagram that I printed from this site (free). Very relieved that we don't need to have our custom cabinetry re-sized to accommodate a new microwave. Thank you!

        Microwave not heating
        Replaced diode works great. your website said 92% diode was problem and it worked. Order fuse in case old was blown did not have to use it.

        No heat
        Removed case,
        Discharged HV capacitor and removed cooling fan.
        Unscrewed ground end of HV diode and unplugged from HV capacitor.
        Installed new diode by reversing the order. In my case, the problem was the magnetron was bad, so I replaced it as well.
