It certainly sounds like something is wrong. My first GE microwave was like this and it wasn't advertised as anything special. After a long life I replaced it with a Sharp (makes most all microwaves) and was disappointed at the cycling on and off. Now Panasonic makes what they call Inverter microwaves with continuous power. I recently bought a GE (probably made by Panasonic) with this Inverter technology and am very pleased with it. Make sure the microwave you have says AccuWave on it, if it does, it sounds like the magnetron may have been replaced with a non-continuous type of magnetron. Was it bought refurbished/returned/clearanced? I think when I was researching this that it MAY have something to do with the type of power supply to the magnetron and not so much the magnetron itself.

Whirlpool Microwave Ovens - Consumer Affairs

All microwaves make some noise when running. Cooling fans, exhaust fans, turntable motor, transformer, and magnetron all make noise. I assume you mean some unusual noise. I need to know more about what kind of noise it is - a loud roar, a rattling sound, a high-pitch squealing sound, a "clunk-clunk" sound or what? By the way, a "klunk-klunk" sound is frequently caused by small debris stuck to the wheels of the turntable support tray. Try cleaning those wheels and the track they roll in.

should be a cover inside the unit,where you can gain access to the bulb.

<- With a full model number from the tag on or in the oven, I may have been able to give you specific help. Without that essential information, I can only give more general advice. I would ask for additional information, but FixYa no longer notifies us experts when such inquiries have been answered. F7 on a Whirlpool microwave is usually a problem with the inverter or other high voltage component. There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components. There's a video here showing how to remove a typical over the range control panel assembly in under 5 minutes.

Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if the switch contact are not good then it will not trigger the processor to switch on the waveguides. If the lights or fan work without any display or action of program being triggered to start then it can be a possible fault on the main board or the processor. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean, solder and reset the board. Now identify the parts by clicking this link: http://www.espares.co.uk/advice/microwave/a/5/141/identifying-microwave-parts.html

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also 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. Check the wave guide covers, if food had deposited then it must be checked or replaced. See link: http://www.espares.co.uk/advice/microwave/a/5/1146/how-to-replace-a-microwave-guide-cover.html

Now keeping clear of the microwave, switch on; use a cup of water inside 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 there is heating without any issues, you can use the microwave safely

Refer to your owner's manual.

If the door is loose the interlocking switches will not engauge properly and the fail safe systen will deni access.
