Setup not working

I just installed a new Samsung SMH7178STD microwave for my mother. It started up fine at first but later that day started flashing SE on the screen. Nothing else works. Any grand ideas would be appreciated.

The -SE-error is a shorted keypad.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

If you would like to have us do this for you, we do that for $39.95 plus part costs.

Please feel free to contact me directly if you need more help.

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

Hi the se flashing indicates a fault with the your membrane switch [touch control/ touch pad. disconnect power for about 20 min and then reconect .it should reset if not replace with original part .ihope it works cheers

Reset did not work for me.  I ended up having to replace the membrane switch.  Samsung took care of it, but it did take two visits by the repair man.

Nothing worked out of the box.

Since it's less than one year old, it would be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

Fan vent door not working

First of all, if it's less than a year old, it will be under warranty and you should contact Samsung to cover the service. You can try the number in your manual or try

There is a drive motor that opens and closes the vent fan door. It or an associated switch may have failed.

Samsung Microwave model # SMH7178STD just stopped working.

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.
