Afternputting time in then push start it shuts down after 8/9 seconds
For model number LMV1683ST
Hi Allan,
Thank you for your question. If the microwave shuts off after a few minutes, you may have a defective or loose door switch. If the door switch is positioned correctly, you will need to test the door switch for continuity with a multimeter. Using a multimeter set to Rx1, ensure the button is depressed and touch the terminals with the meter’s probes, you should receive a reading of zero or nearly zero, indicating that there is continuity. Next, with the probes still touching the terminals, ensure the button is not pushed in, this test should indicate that there isn’t continuity. If your test results differ from those above, you will need a replacement door switch. The part number listed under your model number for the door switches are PS3522738 and PS3529293. If you need help placing an order for them, customer service is open 7 days a week and anyone will be happy to assist you. Please feel free to give us a call. We look forward to hearing from you!

The fan cover in top of the cooking area was burned.
The original cover was burned and actually caught on fire. Research informed me that food can splatter and stick to the cover. The particle will get hot enough to ignite the plastic cover. I ordered the cover and included the fan since it was so cheap, Replacement was super easy. Done in 10 minutes and made my wife happy. She was ready to

One of the switches in a component that door activates when shut.
I replaced the whole component with all three switches in it even though only one switch was bad . Taking out one switch out of the holder unit would probably have damaged the unit that was holding the switches. Easy install and it works great again .
