    I had a smilar problem with my microwave but it mad a buzzing noise and then went dead. I replace the 20amp ceramic fuze behind the control panel and got the control panel to come back to life. I did a 1 ssecond test and it made the loud buzzing noise and went dead again again. I am waiting on a diagnosis from this site before I determine if it will be worth it to go any further or just replace the microwave.

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.

Are you sure the plates were Microwave oven safe? Some dishes have metal in the colors of the design. A snap, crackle, pop noise normally means there is metal present in the oven.

Hi, my problem is with my GE advantium speedcook microwave oven. When using 'speedcook' feature, the oven starts, then there is sparking inside the circuit board area, followed by a loud POP, and this...


  • Select the "Options" menu and adjust the clock display settings if the display is blank. Set the clock if the oven won't start. The clock must be set for the oven to work properly, as oven programming is dependent on the clock.
  • Close the door tightly if the oven won't start. The oven won't start if the door isn't closed. You can identify from the lights whether the oven failing to start is related to the door or to the power supply. If the control panel is illuminated and interior lights are on when you open the oven door, you can be sure the oven is receiving power and any starting problems are due to the door not being closed tightly.
  • Press and hold the "Clear/Off" button if the oven performs strangely. Be sure to hold it for a few seconds. This will reset the GE Advantium.
    But as you mentioned that there is /was a loud noise this is a indication of the unit make any usual noise (groaning, gurgling, etc.?) or was / is it either louder or quieter than normal?It may be as simple as the top door switch or its mount or it may be a bad magnetron or shorted diode.

    Microwave not heating


    In all likelihood the mangnetron has failed, or perhaps even the Power Supply. You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

    hello Frank. Sorry to tell you that the magnetron is going bad and making that terrible noise. Since the inside of a microwave, even unplugged has up to 2000 residual and deadly volts of electricity I recommend either calling a pro or replacing the unit.

    Microwave made loud popping noise


    The magnetron is bad. Probably cost about $50 or $60 for the part. Not too easy to replace, but it can be done.

    Sharp microwave


    If it died as soon as you hit the Start pad, it probably has a shorted high-voltage capacitor. If it died a few seconds after you hit Start, it may be a shorted high-voltage transformer. Can you describe in more detail what happened? Have you checked the outlet for power? Have you checked the fuse inside? I'm happy to help you.
