It bips and flashes
If the oven has a built in temperature gauge, then you should read that for the correct heat. If it does not, I suggest you buy a thermometer that is made to withstand oven heat and use that to tell when it is hot enough.
the oven indicator light stays on and the temperature light but i turn the oven nob on and the oven heat up then i turn off . it gos out tell the temperature cools down. then it come back 0n.
just put the oven on the temperature that the directions tell you,and it'll preheat on it's on. give it about ten minutes before putting anything in it.
The general meaning of "sensor cooking" usually involves using a microwave compatible temperature probe to cook with. Some microwaves have a thermocouple temperature probe that can be plugged into a jack in the cavity of the oven. This (temperature) sensor can tell the control unit in the microwave when the internal temperature of the food item has reached a preset point. Only the factory sensor should be used with a given oven to avoid problems. There are some generic replacements are available and they will work properly and safely if they are the "correct" ones. Consult a microwave technical expert for advice.
i can tell you right now there have been many to acomlish that
In my experience the temperature of the oven makes no difference, but it is how you make them that makes them chewy or not. Most brownie mixes tell you how to mix it to make them cake like or chewy.
If the temperature only has measurements or settings to 250, it has to be Celsius.
The oven's instruction manual will tell you how to do this. The procedure is different for every model of oven.
not during take-off or landing, the captin should tell you when the plane has reached stabilaty and/or the right elavation
Unplug the oven/stove.
it impossible to tell genetics vary
Ovens work because heat is kept confined to a small area. If the oven door is left open, it disrupts the way an oven works. An open oven door will prevent food from being baked evenly. If a recipe calls for say, 375 degrees for 2 hours, the oven temperature will never reach 375 degrees OR stay consistently at 375 degrees for the duration of baking. Plus, you will waste considerable energy, whether the oven is gas or electric. You should repair the oven door, or buy a new stove/oven, and tell others to not keep opening the oven door to 'check' food.
