When using the BAKE setting, the desired temperature is input and the oven begins a preheating phase. The temp will only rise to one degree less than the desired setting, and the oven never reaches the set temperature. For example, when 425 degrees is input, the oven will show that it is preheating up to 424, then it just sits there.

More than likely there is an issue with one of the temp sensors. you will need to press and hold clear then upper on off at the same time then release them then immed. press clear 3 times and hold on the 3rd till the service screen appears. on the right side you will see internal temp and catalyst temp they should be equal or very close. ill bet one of them is alot higher than the other if so the sensor will need replace but depends which one is bad as there are 2 of them. if the problem is on the lower just repeat above but use lower instead of upper

How to preheat oven

Hello, Cristina -

Since you have not stated the make and model of your oven, all I can advise is for you to turn your oven on and set it to the desired temperature and wait for 10 - 15 minutes until the oven comes up to the full heat temperature.

You can read the instructions here, if you wish:

Best wishes.

General Electric oven how to reset thermostat

First of all, most oven thermometers move very slowly compared to the electronic sensors and controls on the oven. To make sure you are getting an accurate reading, the thermometer should be in the center of the oven, the oven should be preheated, then wait another 20 minutes after the preheat beep. If the temperature is less than 35 degrees higher or lower at this point, it can be adjusted via the controls. Usually on GE ovens you press and hold bake and broil at the same time until SF comes up in the display. Then press bake, then use the arrow keys to raise or lower the temperature setting. If the temperature is more than 35 degrees off, you may have a bad sensor, bad control board, or other problem.

How close should the temp control hold the temp

Generally the oven temperature will fluctuate as much as 30 degrees above or below the set temperature. The longer the oven is on, the less the temperature fluctuates. If you measure the highest and lowest temperatures readings with a thermometer after the oven has been preheated at least 20 minutes, you should come up with an average temperature somewhere within about 10 degrees of the set temperature. You can calibrate most ovens up to 35 degrees higher or lower if it is off. Any more than that requires replacing parts.

I dont know how to use the oven properly. when i need to bake or roast something i want to put in my own temperature, but there is no option for me to do that. when i turn on the stove all i have is the...

Hello,

There should be a plus/minus sign OR a up/down arrow to adjust the temp.on the control/touch panel. The default setting is usually 350 and can adjusted up or down accordingly,the display starts at 120 and is supposed to rise as temp. increases.
The bigger issue though is to have it serviced and see why it doesnt rise above 200

Oven warms to desired temp then cools down

Check your bake element. Unually ovens use both bake and broil elements to preheat and just bake element to keep temperature. Your bake element is probably burned out.

If you are monitoring the oven temperature with an analog style thermometer you may actually be ok, but seeing the thermometers slow reaction time.
Some newer ovens actually do pre-heat beep prior to reaching temp in an effort to conserve eelectricity.
A good home test is to try your oven at several different temps to see if there is any variation in internal temperature. Try it one day on 300, the next at 375 and another day at 450. Give your analog style thermometer time to catch up (usually just about 15 min) and leave it on for a half an hour to see if the temp maintains.
Also Beware of aluminum foil AND THE NEW OVEN LINER MATS as they can alter oven performance bay absorbing and blocking the ovens natural heat radiation and convection air flow currents that happen in all ovens, not just convection models.
Another interesting fact is that older ovens used a thermostat in them that operated much like your thermometer and was very slow to react making the oven typically about 100 degrees hotter than where the customer set it. This was just a fact of life before the advent of electronic temperature management and became noticeable when people began trying to bake older "hand me down" recipes in the newer ovens with less than stellar results.
You can mimic the older oven performance by preheating the oven about a hundred degrees higher than called for and after it reaches temp, re-set it to the correct temperature and put the items in right away.
If you find your temperatures fluctuating ask your servicer to replace first the temp sensor and as a last resort the control board as this part is usually pretty expensive.
Good Luck with this!

When I cook my Victoria sponge cake it does not rise is my oven

Well, your temp seems about right, but you may need to experiment. A good thermometer helps in gauging temp, ovens are notoriously inaccurate. All oven are different, but it is usually recommended to go down 25 (15C) degrees from the recipe if you use convection. The type of pan you use has an effect. Glass needs to be 25 degrees less, and nonstick/dark pans brown faster than the insulated type. Make sure that you fully preheat as well, or the bottom may burn. Other than that, convection cook times are less if the bake time exceeds 15 or 20 minutes. Thanks for your question, sorry I can't give a more precise recommendation.

I have a whirlpool range. During preheating the

sounds like you may have a bad bake element. try to see if the unit will get hot when set to broil. if it does then try the bake again. if you get no red hot heat from the bake element then you may need to replace it.
when an element is working properly it will heat to a red hot glow.

Amana Convection oven not controlling temp

I have just checked the baking guide in the manual and have found that it may not be us after all. (Maybe this is why they telll us to read the whole manual. Well, I never have) According to the cooking time for Baking, the range is very extensive. For example, an angel cake at 350 could take from 28-50 minutes, buscuits at 375-400 could take 8-16 minutes, layer cakes at 350-375 could take 25-40 minutes, pound cakes at 325-350 could take 45-70 minutes and fresh pies at 400-450 could take 35-60 minutes. Basically, the baking directions on the box means absolutely nothing to use Amana oven owners. We have no choice but to cook our food or baked goods until they are cooked, whenever that may be. :) Linda
