Morphy Micro wave is good I bought new
It sounds like that outlets GFCI went bad... real bad ....

Quite often this is due to grease or food particles stuck on or behind the waveguide cover.
The waveguide cover is usually about the size of a playing card and often held in place by a plastic rivet.
It can be fragile, and the metal edges of the oven behind it can be sharp, so be careful!
The cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner.
If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean.
Then you can apply some high-temperature appliance paint, available from places like Wal-Mart or Lowe's.
If your waveguide cover is burned, it will need to be replaced.

Hi There!
Check behind the "Wave Guide Cover" on the inside cavity. There may be moisture or food residue behind it. Should be a cover that is plastic or Mica. Really strange that it's sparking being new. Also check that you use plates without gold or silver trimmings (Crockery or porcelein). This will also cause sparking. Remember that microwaves will always go to the first organic source in its path. The wave guide cover, if soiled, is very close to the tip of the Magnetron and will therefor result in arcing. Good Luck, JUS004

The pop leads me to suspect that the high voltage rectifier diode blew.
We have the service manual for this model and have uploaded it to our site here to help you. You will need the free Adobe Reader to view or print it.
A microwave can be dead for many reasons.
It may be the fuse, which is usually located 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.
There
should also be a "mini-manual" hidden inside the unit behind the
control panel or hidden on the left side behind the grille, which is
very helpful when troubleshooting & testing.

Replacing the Magnetron will fix this heating issue you are having with this microwave. The Magnetron is the device that is responsible for the heating action.

I have a GE Profile Spacemaker model JVM3670WF001, purchased I think in 2003. Pop sound, no Heat. Light goes on, carousel goes around,
