Frigidaire Microwave Over the Range

Our Microwave just quit cooking last night. I had been heating a bowl of food. The light inside comes on and the times ticks down but nothing else happens. What is the potential problem? We did unplug it to try to do a "reset" on it. Didn't do any good. The microwave is 3 years old and only used for defrosting and re-heating primarily.

    Appreciate the input but I suppose the only way to know for sure which part would need to be replaced is to have someone look at it. Unless you can tell me how we definitely figure that out.

It could be one of several things. A defective diode, triode, high-voltage capacitor, or even a faulty magnetron. Find your appliance model number, go to, http://www.apwagner.com and put your number in the model search. They should have breakdowns of many most current models. This way you can know what is what and what to look for. Good luck

After 5 years of service, there could have been a magnetron failure but the door interlock (latch) could have failed which would acccount for the turntable failure.

Microwaves and how they work.

--> ­T­he microwave oven is one of the great inventions of the 20th century -- millions of homes in America have one. Just think about how many times you use a microwave every day:

­You're running late for work, so there's no time to fix breakfast at home. On your way to the office, you stop to gas up your car. Inside the quickie-mart, you grab a frozen breakfast burrito and pop it in the microwave on the counter. Later that day, you have to work through lunch. By 3:00 p.m., you're starving, so you grab a snack-pa­ck of microwaveable popcorn from the vending machine and pop that in the break-room microwave. That night, after a really long day at work, you're simply too tired to grill out, so you dish up last night's lasagna and heat it up in the microwave...
As you can see, microwave ovens are popular because they cook food in an amazingly short amount of time. They are also extremely efficient in their use of electricity because a microwave oven heats only the food -- and nothing else. In this article, we'll discuss the mystery behind the magic of "meals in a minute" with microwave cooking.

­A m­icrowave oven uses microwaves to heat food. Microwaves are radio waves. In the case of microwave ovens, the commonly used radio wave frequency is roughly 2,500 megahertz (2.5 gigahertz). Radio waves in this frequency range have an interesting property: they are absorbed by water, fats and sugars. When they are absorbed they are converted directly into atomic motion -- heat. Microwaves in this frequency range have another interesting property: they are not absorbed by most plastics, glass or ceramics. Metal reflects microwaves, which is why metal pans do not work well in a microwave oven.

Microwave cooking ­You often hear that microwave ovens cook food "From the inside out." What does that mean? Here's an explanation to help make sense of microwave cooking.
Let's say you want to bake a cake in a conventional oven. Normally you would bake a cake at 350 degrees F or so, but let's say you accidentally set the oven at 600 degrees instead of 350. What is going to happen is that the outside of the cake will burn before the inside even gets warm. In a conventional oven, the heat has to migrate (by conduction) from the outside of the food toward the middle. You also have dry, hot air on the outside of the food evaporating moisture. So the outside can be crispy and brown (for example, bread forms a crust) while the inside is moist.

In microwave cooking, the radio waves penetrate the food and excite water and fat molecules pretty much evenly throughout the food. No heat has to migrate toward the interior by conduction. There is heat everywhere all at once because the molecules are all excited together. There are limits, of course. Radio waves penetrate unevenly in thick pieces of food (they don't make it all the way to the middle), and there are also "hot spots" caused by wave interference, but you get the idea. The whole heating process is different because you are "exciting atoms" rather than "conducting heat."
In a microwave oven, the air in the oven is at room temperature, so there is no way to form a crust. That is why microwavable pastries sometimes come with a little sleeve made out of foil and cardboard. You put the food in the sleeve and then microwave it. The sleeve reacts to microwave energy by becoming very hot. This exterior heat lets the crust become crispy as it would in a conventional oven.

May Spacemaker XL1800 stop heating food. Was working fine. Then just stop


Is this an over the stove type unit? I have had a few problems with my over the range spacesaver. I think the heat from cooking gets up into the microwave and damages it. The steam from me boiling things on the stove had mine quit heating and I purchased a new one. The parts to replace the faulty ones can be quite expensive over $150.00, so its better to purchase a new microwave.

My frigadare microwave runs normal but wont heat the food


From the description you have provided, the magnetron has shorted. This a job for a professional because there is lethal voltages present that will kill.

Frigidaire microwave not heating over the range


Hello

Try to cook something simple such as microwave popcorn. If the unit does not light up or turn on, check the outlet with another appliance to make sure the outlet is functioning correctly.


Check the fuses or circuit breakers in you house. If the outlet does not work after testing it with another appliance, try to plug the microwave in a different outlet.


Check the hinges and door hooks to make sure the door is closing properly. Look to see whether a small piece of food is clinging to the door, preventing it from closing all the way. Check the release mechanism and the rotating plate to make sure they can move freely as well.


Plug in the microwave and start it a the bag of microwave popcorn inside. If the lights go on but it is not producing heat, listen and try to hear whether the unit sounds the way it usually does. If it does not, there might be problems with the circuit board. This will need to be repaired by a certified Frigidaire professional.


Check the display that shows the time and power. If the display is flickering but it does not alter the operation of the microwave, it is not a problem. If, however, the lights flicker and your food is not heating, there may be a problem in the microwave cabinet.


Listen for buzzing sounds. If there is a buzzing sound and no heat is being produced, you may have to get a new magnetron, power diode, or high-voltage capacitor. These can be purchased from a Frigidaire retailer.


Look at the handle on the door. The most common complaint about all models of the Frigidaire microwave, according to Consumeraffairs.com, was cracked or broken door handles. Frigidaire will replace faulty handles while the oven is under warranty. In many cases, they will replace the handle even after the warranty expires for a "reasonable" amount of time.

Microwave seems to run, but won't heat.


We have a similar problem! It sounds like a problem with the microswitch inside the unit that the door is suppose to engage when closed. If not engaged properly, it will not cook. We had the switch replaced last March but it has started acting up again. We can press in on the door and/or lift it slightly and it will cook. Try putting time on the counter and hit start. It the word "cook" appears then try moving the door slightly and see if the turntable starts turning. If not, then you may have a more serious problem. Good luck!

Not heating anything, very loud


Sounds like the magnetron has failed. This is the component that produces the microwave that heats the food. The cost of the magnetron is about 95% of the cost of a microwave . Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing. There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.
