Microwave power interruption

Everything works until you start to cook, then after about 3 sec. the power cuts off and the display says there is a power failure, check your food. There are not power issues other than that.

My microwave shuts off, black no power when ever I cook tv dinners, potatoes etc. after 2.5 or 3 minutes. After 10 minutes or so, power comes back on and it displays PF. lots of steam inside after.

Hi Kerry,
"PF" is power falure if you didn't aready know this. It sounds to me like the coolig fan might be running slow or there is blocked or restricted air flow through the unit. This cooling fan is only for the HV transformer and magnetron. Sometimes you may get air flow around the door but this is incidental. The PF tells me that the power is being interrupted either at the power source (wall outlet or circuit breaker) or the magnetron TCO is cutting out. It also could be a bad magnetron running too hot. As far as the steam goes, I usually just leave the door open on my microwave for 10 or 15 minutes to let the condensation evaporate.

My microwave stopped working you can input time but when you push start nothing happens it has power and everything just will not start its like the start button does not work

Possibly a bad door switch behind the holes where the latch hooks go into. Usually with the bad switch the timer counts down but nothing runs. It all depends on which switch is bad. Usually 3 switches inside.

When pushed, the 30 sec button says 3 minutes. none of the display buttons work.

Have you inadvertently programmed your microwave for "autostart"?
Your model microwave has the ability to be programmed to go on at any given time of the day/night, even when you're not home so that you can have a defrosted and cooked meal waiting for you when you get in.
I know that if you hit the 30 sec button or the minute button when your micro is programmed to autostart it will tell you the time that it's programmed to autostart or the amount of time that's left for it continue cooking.

Have you tried unplugging it for a few minutes?
This should clear it's memory and then all you'll have to do is set the time on the regular clock if you want.

Here's where you can download and read your owners manual for further instructions on how to use the autostart feature and everything else:

Microwave cuts off after heating for about 3-4 minutes

There is a overtemperature device inside that is shuting you down until things cool off. Take the cover off and clean up everything as much as possible. Grease from the cooking can get all over everything inside and collect dust buildup enough to obstruct the airflow and cause overheting.

New microwave not starting

Chances are the oven is designed for 60HZ and your supply is 50Hz. This will cause the unit to shut down because it thinks it is not getting the proper "interrupt" signal from the power line. You can check the owner's manual (or model number tag) and the manual for the converter.
