    We only had this microwave for 4 months! The other day the Microwave ran for ten seconds then stopped and all the lights on the control panel went out. Searching the Internet for a similar issue said it was a bad control panel!

    However that is NOT the case!

    These microwaves have the cheap non ceramic mini high limit switches that can easily pop!

    Just like the hi limit thermo disc in a pellet stove that is inline with the AC juice to the auger motor!
    At least the pellet stove hi limit discs usually have a red button to reset them or in the case of Travis stoves they automatically reset.

    This microwave limit switch is a normally closed switch that opens at approx 190 degrees. There is no reset button and they do NOT reset!
    So if it dies and opens up then no AC to the control panel and microwave does not work!

    After installing a new switch it is working again.

    I remember my grandma's old wood grained covered microwave that must have been 15 years old when she moved and left it at that house. I probably still works.

    I've yet to have one last nearly that long. My last one made it 3 years before getting fried. Glad you were able to fix yours!

    I dragged my microwave to the curb and threw it away still working. I did this after extensive research and concluded that the food cooked in a microwave was not safe to eat. The violent heating of the food caused a molecular breakdown on a cellular level, and when it enters our bodies it causes the perfect conditions for cancer formation. This is the condensed version of what is happening but there are plenty of scientific studies from Europe to back it up. It is not the radiation from the microwave that cause harm, but the actual food cooked in it. The old fashioned ways are a superior and healthier method to reheat or cook food.
