Question about Samsung SMH7178STD Microwave Oven

1 Answer

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 the microwave and checked. It is just over a year old. There are no lights on, nothing works it is completely dead. Any ideas?

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

When I open the microwave door a fan comes on. When I shut the door it shuts off.


This is done on purpose. The microwave knows you have cooked something and the fan removes condensation from the cooking so it doesn't damage the electronics or the inside of the unit..

Sharp carousal convection smart+easy does it have a fuse just died


First check is the main fuse of the unit. On countertop units, you will need to take the shell off. The fuse will be close to where the cord comes through into the unit. OTR units, this main fuse is usually behind the control panel or possibly behind the vent. Usually the fuse is obvious if blown, otherwise test with an OHM meter, if open, replace fuse.
Some brands will also have a thermal cut-off fuse in the incoming voltage line to the control board. Older Maytags and Samsungs have this fuse in it. This thermostat looking fuse is usually above the oven cavity somewhere under the outside shell. Sometimes you can get to it through the vent of OTR models. Test with an OHM meter, replace if open.
use the VOM, God bless you

It displays SE and nothing works.


SE error means you have a shorted membrane keypad.

With your model number I can detail your options.

Tappan TMV151FS over range microwave starts to work and then dies


Never run the microwave without a load (something to heat)!!! That kills the microwave generating parts.

Sounds like a 'thermal' protect switch is activating after running. Make sure that (if the unit is mounted in a cabinet) that there is sufficient space around the unit for proper air flow and that nothing is blocking the vents. Try setting it on a counter top and heat something. If it works properly and doesn't shut off, the venting space is the problem. You may have to have the cabinet that it sits in redesigned for more clearance.

Samsung MU3250W Shut down


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.

We had this problem. It was installed improperly - to recirculate instead of to vent.
