No just a fuse inside
SOURCE: Goldstar MV1502W
A microwave can be dead for many reasons.
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.
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 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 lead sagainst the ends, it can allow internal contact to be made and make a bad fuse appear to be good.
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 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 the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.

Generally, the most common causes of a failure to heat are:
- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)
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.

While I don't have the exact manual, I have a similar manual which I have uploaded to our site. It may help you or a friend with diagnosis. It's here.

You can find the service manual here.
(Also, the owner's manual is here in case you want it)
I would suspect the magnetron thermal fuse / thermal cutout /
thermostat (depending on which it has) or the oven cavity thermal fuse
/ thermal cutout / thermostat (depending on which it has).
To access some components, namely the oven cavity thermal device, you
will need to remove the oven form the wall, in which case the installation instructions are very handy.

We see (and repair) this
a lot. The problem is on the control panel, which
we regularly repair nationwide by mail for $39.95 postpaid in about a
week or so.
At
our Web site, you can get details of our service, plus we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
Or if you prefer, you can order a new control circuit board for it here for $140.10 plus shipping. (Just enter the model number as MH1140XMQ-1 without the dash).
This light failure often
occurs when a bulb goes out and the filament
shorts, or when the bulbs are removed or installed without first
unplugging the oven from the power line. Either can cause such a
failure on the controller.
The lights can can be
inoperable or stuck on or no bright, too. Sometimes this will similarly
affect the exhaust fan operation or inside light, too.
Feel free to contact me directly (and please remind me of your
full model number from the tag on the unit) for more information & help.
