My goldstar microwave stoped working. No display, its dead. Is their an internal fuse and where is it located. Thanks

MAGNATRON FUSE ... IT LOCATED IN A PLASTIC HOLDER . TAKE COVER OFF. TURN ELECTRIC OFF TOO IT CAN KILL YOU.:)

All units have an internal fuse. Of course the unit is still plugged in. Check in the cabinet above the microwave.

I would suspect the oven cavity thermostat is open.

We have a similar model's service / repair manual and have uploaded it to our site here for free download to help you with disassembly & troubleshooting.

To order Goldstar / L.G. parts, visit Encompass. Since l.G. / Goldstar does not list part numbers in their manuals, you'll probably have to call Encompass toll-free at at 866-779-5835.

when that happen to me i change the bulb and the fuse in of the microwave f the don't work send it to the company that made it and they should tell what wrong.

it is under the casing, you need to remove the casing and you will see them, large power protection and smaller control circuit fuses. the power one may be protected by a black plast sheath

The owner's manual won;t tell you that, only the repair or service manual.

While we don't have that exact model, we do have the manual for a similar model uploaded here.

A microwave can be dead for many reasons.

It may be the fuse, which is usually located behind the grille or on the floor of the oven behind the control panel or between the door switches.

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.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

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!

If there is no display and nothing works it may be as simple as a blown fuse. Try that first but unplug the unit before you do anything.
