unplug microwave.
Take ALL dishes out of the microwave and do a proper check of the inside the cooking area. If you are sure that's ok put the glass dish back in if it has one.
Test that the oven and grill are still functional.?
Do they heat up? If they do then get one of those microwaveable bowls or dishes and put some water into it. Place it back into the microwave and do the check again on microwave heating.
Does it bang or spark again?
If it does and the other heating is OK then the Magnatron to me sounds as it's on it's last legs.
That does not mean you have to scrap the microwave if it is the Magnatron. as a new one can be purchased and installed.

follow this steps and fix it. God bless you
- Inspect the power cordUnplug
the power cord and check for voltage at the outlet. Also inspect for
damage, shorts, or burn marks that can be a possible safety hazard.
- Bad door switchIf your
microwave does not work at all and you know everything is plugged in
properly and the outlet is functioning, then also check the door hooks
and the door release button. Using a volt-ohm meter on RX1, check your
terminals. When your microwave door is closed you should have a reading
of zero. Once the door is open the reading should change to infinity. If
these readings do not match up, replacement of the door switch is
necessary.
- Blown fusesTo determine
if your fuse has blown out, which may attribute to your microwave not
running, you need to pull the fuse out using a pair of fuse pullers. Lay
it down and using a volt-ohm meter on RX1, check both ends of the fuse
in question. If you do not get a reading of zero, then you will need to
replace the fuse.
- Bad fan motorLocate the
fan and remove the leads. Again using the volt-ohm meter on RX1, check
the terminals. If an infinity reading is displayed, it means that the
fan has gone bad and requires replacement.
- Light bulbIf your
microwave light bulb is not working, perhaps it has blown. The first
step is to replace the bulb and power on the microwave. If this does not
correct the issue, the next step is to check the socket and wiring to
verify if that is the problem.
- Light bulb socket & main control boardIf
your microwave light bulb is not working after the installation of a
new bulb, check the light socket as well as the wiring to ensure they
are properly operating. If these sources are functioning properly, the
next step is to check for a faulty control board as a possible root
cause to your microwave light bulb malfunction.

It could be that the buttons are worn out. You'd need to replace the keypad to fix it, which will likely cost about as much as a new microwave. See if you can get it fixed under warranty, also, try cycling the power, it's always worth a shot.

If
your appliance has absolutely no functions at all, remove it from the
mains supply, remove the case and see where the mains lead goes in to
the appliance and follow the cable until you find the main fuse.
ONLY
USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual
cause of this fuse failure is the door switches are contaminated or
sticking. Check the door switches before putting power back on to the
appliance.
Hope this helps.
