Micro will not heat,blows air ,lites up,takes time commands but n

If you know DMM then only you can fix it. Check magnetron continuity and the transformer continuity. Mostly magnetron blows up. Danger microwave has 5000 volts in it Thanks Discharge capacitors

Yes, take the rack out and recycle it. I do not know why these micro-wave company put racks in the micro wave ovens. You get some insulation on the inside the micro flaking off next the rack.


The mega-tron tube is a very high energy transmitter. The energy will come out of the top inside the micro wave oven in a wave guide. Micro wave energy that generation by the tube is high frequency into Gega Hertz. You have a metal tray in side the micro wave acts like a big capacitor it stores energy in form of heat the next you know it look like Marconi is putting on a lighting display.



Leave the wire tie on a loft of bread and put in you micro wave oven to defrost. The next thing you might see is a load bread burning, instant toast. ----The use of micro wave were invented by the British before WWII. The mega tron tube generation very high frequency radio wave and these wave struck an object 100 miles away some of this beam energy would balance back to a receiver-----You have Radar.... I wish you and your family well being and be careful of micro wave ovens it can burn from inside out. GB you...stewbison

If you open the door of the microwave can you smell an odd odor? if yes the magnetron is probably fried "heats food" the other parts that need to be checked are the high voltage capacitor and diode. I recommend appliance repairman or tv technician to further check with an estimate.

Hi,

Here is a tip that will help you to figure out what is wrong with your Microwave Oven....

Microwave Oven Basic Troubleshooting Tips

Micro wave as the name suggests produces heat when the micro waves aimed at an object causes the water molecules inside the object to vibrate hence producing heat.The gadget responsible is the magnetron. If your magnetron is not receiving ht voltage or receiving but faulty, then your micro wave wont work please take precaution when opening micro wave due to high voltage caps that remain charged sometimes even when it is off.check the high voltage fuse/ diode and capacitor if they are fine and the step up trans former o.k then the only option is to replace the magnetron

micro waves use a tube inside that generates micro waves and like a light bulb they eventually blow out. the tube is not considered replaceable and cheaper to just get new unit.

FIK IT THE HEATING ELEMENT IS STRIGHT FORWORD AND COST IS CHEAP, GO FOR IT .

You will have to remove the micro wave from it's mount. Once you have it down, look at the top of the micro wave. There will be a panel that you will have to move from one place (where it is now) to another. This panel will either be on the top of microwave or if the mounting kit has a top plate, it will be on it. The panel normally has two screws holding it in. When you remove it, you will need to re-install it so that it blocks the air flow from coming out of the front. There should already be screw holes where you are to install it. When you have it moved, re-install the micro wave.
I hope I didn't confuse you. The only reason it's not blowing out the top is because whom ever installed it didn't move the panel. All over the stove micro waves come with this movable panel so you can vent it either way you want. If you have the installation papers, it will explain this better. Good luck.

Replace the HV capacitor

Q - The microwave display counts down and the inside light is on,  but nothing is heating and the fan is not running.
A - This most commonly is a bad door switch, other possible problems are a faulty relay or solder joint on the power module, but a bad door switch is most common.
 Q - My microwave is running and sounds like it is working but will not heat up anything.
A - Many thing can do this but, common things are....loose high voltage wire.....poor solder joint on board.....magnetron.....power relay.....
Q - The microwave makes a loud "hum or buzz" noise but will not heat up the food?
A - 9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section.
