If when you press the start button the turntable starts but no heat then magnetron is faulty otherwise if nothing happens then the touchpad itself is faulty.

Popcorn is a low-moisture food which can cause a microwave to overheat, as can a failure of the cooling fan or blocked vents.

You should always turn a paper plate upside-down on the turntable (slightly off-center for better heating) and place the popcorn container on top of that.

The paper plate elevates the popcorn for better exposure to the energy and protects the turntable from excessive heat.

Placing food off-center instead of in the center increases exposure to the energy and prevents the same spot on the turntable from being overheated repeatedly, which leads to material fatigue and cracking.

It's also a good idea to put about 1/2 cup of water in a 1-cup microwave-safe container in the corner of the oven when cooking low-moisture foods like popcorn, bacon, and potatoes.

The microwave's magnetron has a thermal protector (thermostat, TCO, or thermal fuse) attached to it.

If the magnetron gets too hot, it can be damaged or destroyed, so the thermal protector opens and disconnects the power to the whole oven.

If it is a resettable device, the power will be restored when the device cools. If it is not resettable, the device must be replaced.

I am not surprised! Cloth of anysort is not recommended to be placed in a microwave oven!

That includes undies and socks which many try to speed the drying time of.

Regarding the popcorn.. The oven is overheating due to a possible containment in a hutch, where insufficient airflow is available to lower the temperature. Pull the unit away from the wall to allow more airflow, clean the vents and help it breathe.

HI. your control board has failed. you will need to replace the control board asap if possible.

If the supply voltage is low it will take long time to heat foods. The second reason is the Magnetron. Since it is in the warranty period you can call at the sharp authorised service center. They will do it free of coast.

The cooling fan is a must!

Otherwise, the magnetron will be ruined, and that drives up the repair cost.

We're happy to help and we appreciate your thoughtful rating of our answer.

We had the same problem with our brand new Magic Chef. Before going through the trouble of taking it back I called Home Depot. After talking to a Home Depot Rep I am told that the overheat sensor is under the glass plate directly beneath the popcorn bag. Popcorn gets very hot and the heat of the popcorn causes the sensor to shut the machine down. I would imagine this would be the same for a baked potato.
Very poor design.
I was told to put a microwave safe plate down and put the popcorn bag on it. This should help to reduce the heat and not trip the sensor.
A safety sensor is great, but not if it keeps tripping the machine and shutting down!
