Hi I have a Samsung SMH9187 micowave that is dead (no display, light, fan, mirowave).

I checked all of the easy thing. ie circuit breaker not tripped, plugged something else into microwave outlet and it ran, plugged microwave into another outlet and it did not work. It's not the wall power. I removed the control panel, removed all of the connections, cleaned with an eraser and compressed air Then I put it back together, the clock, light and exhaust fan worked. I then pressed the 30 second button to start the microwave. It hummed briefly and then went dead (everything lights, fan, microwave, display). Like an internal fuse blew. Help!

Sounds like the main fuse blew. It's either near where the power cord enters the cabinet, or behind the control panel (if an over the range unit).

You may also have some type of failure in the high voltage circuit; based on your description of the symptoms.

You may have a blown internal fuse. You''ll need to unplug the unit, remove the outside cover and follow the line cord and you should find the fuse.

Replace it with the EXACT same value that was labeled on the original fuse. You'll probably be able to find a replacement at any Radio Shack store or hardware store.

Replace the cover and plug the unit back in. Hopefully nothing was damaged and the unit will play again.

Please let me know if I can be of further assistance to you.

Good luck!

UPDATE

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.

SOURCE: No power

It may be the fuse, which is usually located behind the grille or on the floor of the oven behind the control panel, between the door switches, or inside near where the cord goes into the chassis.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

Or another common problem, is surge damage on the control circuit board. We regularly repair these control units for customers nationwide with our guaranteed $39.95 service.

Feel free to contact me directly for more information & help.

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.

Unit fails when attempting to cook.

see the steps and fix it. God bless you

  1. Main control boardIf your microwave runs for a few seconds and stops, the first thing to check is the main control board to ensure that a shortage has not occurred. If the part is defective then it will need to be replaced to prevent continual shut offs. If this is not the issue, the next step would be to check for a faulty touchpad.
  2. Touchpad/Control panelIf the control board is not the issue and your microwave continues to shut off after running for only a few seconds, the next thing to check is your touchpad, which is also known as a control panel. Although uncommon for this issue, symptoms are usually that the display and some buttons are working properly; however, when selected some buttons are not functioning. If this is the case the touchpad will need to be replaced.

This problem is caused by a microswitch that is sticking in the closed position. Inspect and replace the defective microswitch in the latch assembly.

The oven will not work. I checked the fuses and they are good.

Is this a dead mirowave or semi dead. the display works, light works in the oven when door opens.
If this is the case... you may have a power supply board failure or the magnatron is defective
Check the power supply first, because it would be cheaper to repair then the magnatron

I went to use my mirowave & it is completely gone. I pushed every button that I could & nothing happens. What should I do

first check the breaker in the electrical panel. your microwave should be on a circuit with nothing else. Depending on when the house was constructed. If the breaker is tripped turn it off and back on. If the microwave is plugged into a gfic outlet check to see if the receptacle needs reset. There will be a reset button on the receptacle. Their may be a orange light on the receptacle.

Gold Star convection microwave model ER-930C

If you have a sentimental attachment to this microwave (lots of the older ones feel so much more "quality" than the flimsy throw away versions offered today), then you might want to pick up a service manual to diagnose your issue. Here is one being offered and it has a troubleshooting guide. http://www.analogalley.com/osccart/index.php?manufacturers_id=61
