HOW MICROWAVES WORK Microwave ovens are complex and sophisticated, but they operate on a very simple premise. They warm foods and liquids using microwave-frequency sound, rather than a gas burner or an electric heating element. How microwave energy is produced Why some foods cook better than others Safe, quick, and inexpensive How microwave energy is produced Your microwave oven has a small transmitting antenna, much like a radio station or TV station might use. The microwave oven converts the electricity from the house into an extremely high voltage, which feeds the "magnetron, " which converts the high voltage into radio waves. The radio waves funnel into the cooking area of the oven, which makes the molecules in the food or liquid resonate (vibrate) wildly?which causes friction between the vibrating molecules?which generates the heat for cooking. Why some foods cook better than others Whether a food type is suitable for cooking in a microwave oven has a lot to do with the structure of the food--or the lack of it: Consider bread. It has an internal structure of air pockets. When the microwave gets all of the molecules in the structure vibrating at microwave frequency, the structures break down and the bread becomes tough and inedible if cooked too long. Now consider water. It has no structure. When the microwave frequency gets the water molecules vibrating, they rub against each other creating friction--then heat. Because they have no fragile structures to break down, foods with high water content tend to heat nicely in the microwave--including vegetables, soups, and so on. Safe, quick, and inexpensive Because microwave ovens use radio waves, rather than radiant heat, to heat food, they are considered to be quite safe. Also, they don't introduce anything unnatural into the food, and they are more energy efficient than standard resistance cooking devices. Q - My microwave seems to shut off every once in a while, what might be wrong? A - Make sure you hear the fan is still operating in your microwave. Next is to make sure the air intake grill on your microwave is not plugged up with air borne dust and dirt. Use an old tooth brush to help clean off the grille area. 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. 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 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 went dead when I opened the door ( same problem as closed the door ). A - This often is a stuck or faulty door switch and it has blown the interior microwave fuse. Q - My microwave is completely dead. A - House fuse has blown or interior fuse inside the microwave has blown ( usually a part inside the microwave makes this fuse blow ) Sometimes a bad fuse holder inside the microwave cannot hold the fuse tight enough and the fuse will blow as well. Q - The fan in my microwave oven is not running will this hurt my microwave? A - YES, the fan cools the magnetron and electronics, take the microwave in for service, most fans are not too expensive to replace. Q - My microwave blows the fuse inside itself as soon as I push the start button. A - Usually a shorted high voltage capacitor...see components section. A copy and tip from Prashanth: Description of problem (Maytag CMV1100Q) : Microwave stopped working while cooking. Replaced a 20AMP fuse. When the cook cycle starts, microwave makes a groaning noise and stops. It loses power since the fuse is blown. Solution: High-voltage capacitor shorted. Replaced it and microwave works fine. Its located behind the fan underneath the high-voltage transformer. Remove the vent fan hood Remove the display control panel by removing the screw Take pictures of all the connections behind the control panel. Unhook all connections Remove the connections to fan Remove the fan Remove the screws and connections for interlocking switches. Make sure the high voltage capacitor is discharged! Remove the high voltage capacitor and replace Retrace the steps and put everything back. Microwave works great now. Q - I burnt something in my microwave and now it is dead...help! A - The fuse inside the microwave may have blown, but more commonly the flame/oven thermostat has sensed the over cooked food and the flame/oven/cavity thermostat has opened up - Info on that click on the link below for which u have the doubt http://www.applianceaid.com/micro.html

SOURCE: Inglis electric freestanding range model #IRE3230- Oven no longer working

If the oven and the electric panel no longer work, this is an electronic problem. The burners and the oven light will not be effected, nor will the fuses. The electronics card will need to be replaced by an appliance technician.

If your ignitor looks real dull orange then that is what is wrong. It needs to be bright as the sun or it is weak.

SOURCE: The oven of GE Profile range simply stopped igniting

If it is a ge it would have a glow bar ignitor, either a flat rectangle shaped or a round ignitor. That is want the problem is 95% of the time. It is pretty easy to do. The floor of the stove will come right out and it probably has two screws in the back corners you can see. Remove them and the floor will lift out and you can see the burner and the ignitor.

Bottom oven isn't heating to desired temp. Considering swapping the heating elements to see if one is faulty - thoughts?


try thermostat first. verify heating elements operational, if so check if tstats are same. swap if so, If not jump out tstat and see if higher temp achieved.

My oven is not heating up properly, it either doesn't heat up or it takes a very long time to heat up. The range top works fine and the broiler works, but when i set it to bake it doesn't or takes long.


There are two possibilities for problems with the range. If it has a "timed bake" setting for the oven then it's possible that the last person who used it neglected to return the setting to the manual mode. In "timed bake" mode, the oven will heat to approx. 160 - 185 degrees, what is called a "keep warm" temp. It will maintain that heat setting regardless of what you set the oven temp control to, as long as you're not in the time frame that it's set to bake. This will make trying to bake anything a very difficult procedure.
The second possibility is that the oven glo coil igniter is cracked and will not heat to the proper temp to allow the electricity to flow through it to the oven gas safety valve to allow it to open and let the gas flow to the burner. These things are ceramic and for some reason crack in normal use. If it has a top broiler, that unit is obviously good. Unfortunately, the igniters are seldom interchangeable. You would need a tech to check the igniter with an ohmmeter.

Oven does not maintain a consistent temperature


Is this oven gas or electric? If it is gas then it can be normal to see 30 to 50 degrees difference in tempature. The tempature in a gas oven works on the average tempature. For example: The oven tempature may rise all the way up to 370 degrees. Then the burner will shut off. And then the tempature can drop all the way to 330 degrees. Then take 330 and add that to 370 then divide that number by two and the average tempature will be 350. If your oven is electric then the tempature should be much more consistant but can have a 10 to 15 degree variance. Also the standard oven tempature guage that you put in the oven or even the temp guage built into the oven are not very accurate. We us a Fluke meter with a thermocouple to calibrate an oven. So to check your oven for proper tempature regulation you will first need to let the oven pre-heat for about 15 minutes. Then place the thermocouple in the center of the oven. If the oven is electric the take a temp reading every 5 minutes and average them out. If the oven is gas then you will need to take a temp reading when the tempature reaches it's highest and lowest points. Take at least 5 consectutive readings and average them out. You should get an average within 10 degrees of set temp(350 degrees). If it is off by 35 degrees or less you can usually caluibrate the thermostat back to proper temp. This procedure can be different for each range model. If it is more than 35 degrees off or you are getting irratic readings then the thermostat or thermostat components might need to be replaced.

Viking oven only one burner will light


http://www.vikingrange.com/MEDIA_CustomProductCatalog/m20127_f20254.pdf
Go to this web site. It has a manual on Viking ovens.
Usually, when the set temp is reached, the flame will cycle down to what is called "Minimum Blaze". This is to put heat into the unit at the rate that it leaves the unit. It helps to hold temp rather than cycle off and on. It cycles high when temp goes below set and then cycles down when set temp is reached.

Oven won't heat up at all.


broiler on top of oven?? if so it might have a second ignitor that is working. Most units now with gas have an electric ignitor to start gas ovens. What they do is send electric current through an electric "wire", when enough current is flowing through wire to open gas valve the wire is hot enough to ignite the gas flowing over it. When you turn on the oven look at the burner and after 1 imute or so you should be able to see an Orange glow in bottom of oven if not I'm sure its the ignitor, if glows then probably oven valve is bad. I'd guess ignitor because most oven makers use this ignitor to mantain a warming temp (around 100 degree's) so since your display doesnt register over inital "start" temp of 75, i'd bet ingitor not coming on at all

G E oven temp fluctuation


No, that is just fine. As a matter of fact, older ranges often had 50 to 60 degree swings in temp. Your oven temp (assuming your thermometer is dead on accurate) is 347 + 365 / 2 = 356 degrees when set at 350. I never mess with ovens which are within 10 degrees of set temp. (when checking the temps, make sure to take the readings after the oven has cycled on and off at least three times, and use a good digital oven calibration thermometer)

Oven does not maintain temp.


It sounds like a thermocouple problem. While using the broiler, you gave the gas set to full and the thermostat is basically out of the loop.
