Samsung SMH7159 just quit working. It is plugged in, the outlet has power but it does not seem as any power is getting to microwave. Display is blank, no light comes on, no power, but the slide out hood is out and if I try to push it back in, it automatically goes out again. I replaced the fuse but that didn't help. Any suggestions?

SOURCE: MY MICROWAVE WILL NOT DO ANYTHING

I couldn't find those exact trouble codes, but a common problem is when the controller gets damp, either from steam rising from the cooktop or someone spraying cleaner directly on the keypad. Cleaners should always be sprayed on a soft cloth, then wipe the keypad with the cloth. Also, GE / Samsung codes of F1, F2 and F3 may be the same since Samsung makes GE microwaves. Those would mean trouble with the temperature sensor, keypad, or control panel. Assuming your control panel is clean and dry, it may be time to call for service.

I have this Samsung MW 1080 STA for four some years, and lately showed the code A-1 in the display out of nowhere, in the middle of night, or during the day without anybody touching or using it. It'll beep twice, then, go to A-2 and A-3, and back again. When you cancel, it will disappear, but it will come back right away in 2 to 3 seconds. It becomes a headache because I had to unplug it after each use. Any ideas, please?

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

If you or a friend decide to look into it, we have critical information on safety, disassembly and door switches at our site, linked here on Fixya: http://tinyurl.com/yzjozk

We had the same problem and fixed it! Try hitting Pause/Cancel button until it shows zero on the display. Then press Kitchen Timer button and input 1:00. Then press start. Our microwave began working after trying that. Hope it works for you!

It could have been steam or humidity.

If this is an over the range model, be sure you always use the hood vent exhaust fan when you're cooking on the stove top.

Whether it's a counter top or over the range top, always be aware that the cooling fan is running when it's cooking.

When in doubt feel for air flow through the vents.

Good luck.
