    How Do You Install The 3B74133K Fuse?Teresa Hood
    December 21, 2017
    How do i install the 3b74133k fuse in a lmhm2017st microwave?
    For model number LMHM2017ST
    Hi Teresa, Thank you for your question. Before you begin any repair please unplug the appliance from the electrical outlet or turn the circuit breaker off. NOTE: If you are not comfortable doing this yourself, please get an electrician to do this repair. Before you begin any repair please unplug the appliance from the electrical outlet. Use a Phillips head screw driver to unthread the screws securing the grill. With the screws removed, open the microwave oven door then the slide the grill to the left and lift it up to remove. Next remove the control panel mounting screw then lift the control panel up to detach. Then remove the screw holding the inner access panel and then release the panel from the retaining clips. To avoid injury, you will need to release the potentially dangerous charge from the capacitor. You can do this by place a screw driver with an insulated handle across the terminals. Be careful not to touch the screw driver blade. Now use the pliers to detach the old line fuse from noise filter board. Install the new fuse by snapping it into the bracket. Reinstall the inner access panel securing it with the screw. Now insert the control panel tabs to the slots in the frame and push the panel down. Secure it with the mounting screw. Insert the tabs of the grill into the frame and slide it to the right. Shut the oven door and then secure the grill with the screws. Plug the power cord back in and the microwave should now work. I hope this helps. Thank you and have a great day!

    My microwave is dead. I think it might be the fuse but where is it so i can replace it? Thanks
    For model number LMV2073ST
    Hi John, Thank you for your question. This part is located on the inside of your machine in the top. You would have to remove your vent grille and then a second metal grille to get at the part. However you have to be very careful. Unplug your appliance and make sure to safely discharge the capacitor in your microwave. If you do not safely discharge it, it could give you a serious electric shock. I hope that helps. Good luck with your repair.

    Lights, fan and digital readout all work. Turntable doesn't and no heat. Will fuse fix this or does it sound like a door switch????
    For model number 721.85063010
    Hi Leann, Thank you for your question. If the microwave will not heat and the turn table will not turn, the door switches are likely the cause. You will need to test the parts with a multi-meter. Here is a link to one of our videos on YouTube that you may use as a general reference on how to use one, https://www.youtube.com/watch?v=bWC44fHn0As. If the switches check out fine, where you are not getting heat, you should also check the magnetron, the fuse and switch holder. If the turntable is not turning you should also check the turntable motor. We hope this helps. Thank you and have a great day.

    I have replaced the light bulb in the bottom of the unit. The old bulb doesn't look like it's bad. Installed new bulb, still doesn't work. Is there a fuse somewhere for the light? If so where, and what can you tell me about the fuse?
    For model number LMV1683ST
    Hello Joe, thank you for your question. There is no fuse for the functioning of the lights. If the bulbs were replaced and didn't fix the issue, I would recommend replacing the Microwave light socket Part #: 6620G00007A. I hope this helps!
