We have same microwave and we have problem ... We removed up cover on face and start the microwave ... There are sparks fire at right back ... Is it magnetron there ???
Thanks for your help
If there is spark please do not switch on
unless you have confirmed the fault. It is possible that the Magnetron is
leaking and sparking to the ground. As you have mentioned it was stored, it is
quite possible that insect can get into the oven and create soft spots. When
you switch on these will create a short and make the voltage jump and in the
long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if
so wipe clean and dry, check the magnetron and area clean and use an jet air to
clean off.
Now switch the microwave power on and use a cup of water to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can
be faulty. Replace with same type. If not check the waveguides within the cabin
for food particles that can burn and spark, check for rust that can corrode and
spark when the ceramic paint has worn out.
If there is heating without any issues, you can use the microwave safely

Somtimes the wave guides with food particles can burn and smoke if so replace the wave guide.

Also remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Now keeping clear switch on , use a cup of water inside to test.

The cracking spound is the spark jumping. so if there is spark please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is leaking and sparking to the ground.
