    same problem, the light works but the turntable and heating doesn't

  • mrlandscape Nov 25, 2008

    My Viking micro sounds like the same issue. The turntable works, the fan works and the light is on but will not heat. The general concesus is the magnetron.

My microwave doesn't work, but display works


I would strongly consider replacing the microwave oven, prices have dropped considerably. The problem you are describing is in the keypad controller board.

MY MICROWAVE DOESNT HEAT UP FOOD JUST COOKS


Hi.

The wave emitting part inside the microwave oven is called the magnetron. The waves emitted by the magnetron generate heat in food. When the microwave is running, turntable turns and light comes on but there is no heat it means that either the magnetron is faulty or the magnetron is not getting power. When the magnetron is not getting power parts such as the high voltage diode or capacitor must be tested or replaced. Testing and repair must be carried by a technician.

Frigidaire PLMV168K2 micro wave stopped heating food. Still has turntable and light functions. Seems to have more of a power load after initial start. The buzz is more intense than normal.


A loud buzz is a symptom of a shorted magnetron or high voltage diode. Would recommend that you take it to a qualified repair facility if you want it repaired, but if the magnetron has failed, the part costs can equal that of a new oven.

My microwave starts however food does not heat up.


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

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.

I have a JVM1603BJ03 space saver micro wave. The turn table cracked in two, the plastic support device to turn the glass table has desenigrated into several small pieces. It appears the micro wave is...


Do you cook a lot of popcorn?

Do you place your food items in the center of the turntable as opposed to placing them off-center?

Both can cause repeated heating of the same spot on the turntable, which can stress it and allow it to crack.

You can buy replacement parts here.

I suggest that when you cook popcorn, place a paper plate or two upside-down under the bag and always place your food items off-center on the turntable tray.

Once you have the new parts, I would suggest at least a quick heat test. That is to heat one cup of water on high and it should boil in about 2 to 2-1/2 minutes.

If you would like to perform a more standard heat test, please see my Ask Mr. Microwave page.

If your magnetron is indeed running too hot, then it is probably dying. Sometimes - like a star - they can burn hotter right before they die.

We're happy to help and we appreciate your thoughtful rating of our answer.

Microwave does not heat food placed in the center of the turntable. Leaves a cold spot in the middle of the food.


This is normal. That's why I always recommend to my customers that the food be placed slightly off-center on the turntable. An analogy I refer to is stirring paint: If you stir paint with a stick by simply rotating the stick in the center of the can, it's far less effective than pulling the stick around an imaginary circle halfway bewteen the center and the edge.
