Question about Samsung SMH7178STD Microwave Oven

1 Answer

Samsung Microwave model # SMH7178STD just stopped working.

My Samsung Microwave model # SMH7178STD just stopped working. It has been working fine for three years. One day the door was a little difficult to close, like it was off center or something and when it closed, the microwave lost all power. We have power going to the outlet so that's fine and we just checked the fuses and they visabily they look ok. We have unplugged the unit and then plugged back in but that didn't make a difference either. Any ideas on what the problem(s) could be?

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

I have a samsung smh7187 microwave over the range and in the middle of cooking it just shut off. The vent at the top of the unit is still open. The outlet is fine, other things work fine in it-I unpugged...


I would suspect the oven cavity's thermal cutout / thermostat, the magnetron's thermal cutout / thermostat, and/or the fuse.

Deep humming sound


This usually means the magnetron is failing.

Just be sure the internal cooling fan is working by making sure you feel air flow. If not, call for service right away.

The magnetron part cost is covered beyond the normal 1-year warranty, so when it gets worse or stops heating, you'll have to call for service.

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 samsung.com

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