Most likely the power capacitor is shorted.If you know someone that is just alittle familiar with electronics, they will know what to look for.The part will look like a somewhat long large silver 9v battery with two metal leads.Normally toward the back of the microwave and below the cooling fan.With a volt-ohm meter this capacitor can be checked.on the meter if you get a reading ,its bad, if you get no reading(open), its most likely good.Ninety percent of the time it will be bad.If it is, just replace with the same value and your ready to go.

Beeping sound with SE or 5e code

Unless there is grease, moisture, or some other foreign material deposits on your control circuit board, "SE" means you have a shorted membrane keypad.

What is SMH18165 -Error code: E-13?

It is a T1 maximum time error (oven did not preheat properly). usually caused by a failing thermistor/sensor, a bad seal, bad control circuit board or connector. Unless you are a really good electronics expert and have the test equipment for after-repairs microwave emission measurement, it has to be dealt by the service people.

Shows SE and not working

The SE error indicates a short in the key panel. You can try resetting the microwave by unplugging it (or turning off the circuit breaker). Leave it off for a minute or so. If the code recurs, check if the microwave is under warranty. If it is still covered by the warranty, contact Samsung for repairs. If it is out of warranty, decide if it is worth sending the microwave in for repairs. (You'll have to pay a fee for diagnosing the problem; that will be applied to the actual repairs if you have the unit fixed.)

I hope this helps.

I have a samsung microwave. Some of the paint is chipping off (under the revolving plate) and there are some scorch marks on the sides. I have heard of being able to touch up with microwave safe paint. ...

This is a special white enamel paint that is very hard to find, I don't have any personally but the manufacture use to supply the paint to people like myself to do touch up repairs. The only thing I can suggest is hound Samsung for the microwave paint because the magnetron will eventually short out making the oven useless.

Door got slammed and now it does nothing

There are two or three switches operated by the door latches in a microwave oven. When the door is slammed, they can be damaged or knocked out of adjustment. If the control board thinks the door is open, it won't allow the oven to operate. It's best to let a professional check the oven and adjust or replace the affected parts. Microwaves are hazardous devices, with lethal voltages exposed when the cover is off. Also, repairs involving door repairs can cause microwave leakage if they aren't done properly. But once the switches are operating properly your oven should be fine.

Timer runs but oven does not.

If the lights and turntable are both working but there's no heating, the oven has a bad magnetron tube (the microwave source), a bad part in the tube's power supply, or there's a problem with the control circuit board. If the turntable isn't turning, the trouble may be caused by one of the oven's door switches. Microwave ovens can be dangerous to work on, and there's a chance of leakage if repairs aren't done correctly. You should have a professional diagnose the problem and give an estimate. For some repairs it may only cost a little more for a new oven.

Hope this helps. Thanks for using Fixya!

Sharp R-1490 microwave 2000

the fuse to the magnetron may be blown or the mag it's self is gone. if the door switch was bad the unit wouldn't rotate the carousel. if it is the fuse (check with a multi-meter and check continuity across both side of the fuse, acheap one will do) if it is good, time to replace the micro, as they are cheap and repair would cost more than to replace. hope this helps.

Microwave make a deep humming sound ,does not heat and the circuit breaks

I would say your magnetron has failed.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

If it's within the one-year time frame, the repairs should be free.

My microwave stopped working and I'd like to try and fix it myself. Any suggestions?

Because microwave leakage can be hazardous and high wattage is present, limit your microwave repairs to light bulb changes if the light bulb is easily accessible. For other repairs, call a qualified technician to make repairs on a microwave oven. If it doesn't work and the light doesn't go on, be sure it is receiving power.
