    • First check to see if the interior of the microwave is dirty. Food or tin foil could be the reason that the microwave is sparking.

    • If the interior of the microwave is dirty, clean it. A spotless interior is recommended. The interior should look like the example in the picture.

    • If the microwave continues to spark after the interior has been cleaned, that could indicate that the diode may be broken. The diode is what attaches the capacitor to the back of the microwave.

    • A multimeter can be used to measure the resistance of the diode. The multimeter must be on the resistance setting or the diode check setting. If the diode reads zero in both directions, then it is broken.

    • Sparking inside of the microwave may also be the result of a broken or misaligned magnetron. If this is the case, it is recommended to take the microwave to a qualified professional or completely discarding the unit and purchasing a new one.

    • Fixing the magnetron without the aid of a qualified professional is NOT recommended. The magnetron is an emitter of microwave radiation and tampering with it may lead to serious injury or death.

Is the magnetron the failing component if you have this microwave or perhaps a 1983-1985 model quasar brand and the microwave doesn’t turn on after hitting “start”, a timer goes but no microwave heating is engaged?
