Oven not working properly

How to change lower element in DeLonghi Airstream Convectio Oven??

Preheat ovens only when necessary. With conventional ovens, keep the preheating time to a minimum. Unless you're baking breads or pastries, you may not need to preheat the oven at all.

Food cooks more quickly and efficiently in ovens when air can circulate freely. Don't lay foils on racks. If possible, stagger pans on upper and lower racks to improve air flow.

Use glass or ceramic pans in ovens. You can turn down the temperature about 25°F and cook foods just as quickly.

Do not open the oven door often to preview the food. Each time you open the door the oven temperature drops by 25°F. Watch the clock or use a timer instead.

Full-size ovens are not very efficient for cooking small- to medium-sized meals, it generally pays to use toaster ovens or microwave ovens.

Check to be sure the oven door gasket is tight. Adjust or replace gaskets as required.

If you have a self-cleaning oven, consider using the self-cleaning feature immediately after regular baking when the oven is still hot. Less energy will be required to reach the cleaning temperature. Try not to use the self-cleaning feature too often.

Keep range-top burners and reflectors clean; they will reflect the heat better and save energy.

Match the size of the pan to the heating element; more heat will get to the pan and less will be lost to the surrounding air. A 6-inch pan on a 8-inch burner will waste over 40% of the energy.

On electric stove-tops, use only flat-bottomed pans that make full contact with the element. A warped or rounded pan will waste most of the heat.

When cooking with a gas range-top burner, use moderate flame settings to conserve gas. Also make sure the pilot light is burning efficiently, with a blue flame. A yellowish flame indicates an adjustment is needed because the gas is burning inefficiently.

Whenever possible, use a pressure cooker. By cooking food at a higher temperature and pressure, cooking time is reduced dramatically and energy use is cut by 50-75%.

I think the burner coil is damaged or needs to be replaced. Check it if its damaged then you should replace it then it will work surely at definite time.

On any gas appliance there is a high and a low limit temp stat which could be indipendant or on the gas valve it's self, that is faulty.
When the oven reaches temp, it cuts out. sounds like faulty over heat stat.

Seems the Thermocouple (instrument that lets the oven know the gas is lit) is not working properly. Your ignitor is working thus allowing the gas to burn...but the heat is not moving down the thermo line to register as being lit. Thus the oven thinks gas is being pumped but not burning and turns off as a safety precaution. THere must be a thermostat sensor...usually a wire or tube that allows the heat from the burning flame travel towards a sensor...this is faulty...remove and replace.

Start earlier?
>> check all elements for current,
check seals
check temperature calibration (allowed to be 15% ie 180 can be 153 or 207 Celsius!) no wonder Margs' scones cook faster at her house :-)

The sensor on the burner is not sensing the flame. It could be the sensor itself or its' controller. You need to call for service.

This is what I would do: I would unplug the range and connect my test cord to your range cord. I use an ammeter along with my test cord to read the amp draw of the bake ignitor. If it cannot get above 3.5 amps I know the ignitor is bad or weak. Since the oven is working that means there is a good circuit. In order for the safety bi-metal to open the amp draw must reach 3.5 amps or better. So to me I am thinking bad ignitor. To get to it I remove the door oven racks and bottom, I then remove the flame spreader and unplug the quick connect to the ignitor. I remove the burner and ignitor and replace the ignitor on a work bench. I am too old to be bending over and trying to do any parts replacement inside an oven. LOL. I have a training film which shows how the silicone carbide ignitor works HERE. Post a model number and I may have a service manual, do not forget to rate the answer.

Hi there, it is possible of the pilot being too close, but usually does not have that effect, unless the pilot is too small. But if you replaced the pilot, it should be clean, so next I would look at the gas pressure, if this is too low, the flame won't have proper burning speed, and strength, and could get drawn out. The control valve may be of the type that has a regulator built in, you may need someone skilled at gas pressure measuring, to do this, your gas supplier, appliance professional, plumber, should be able to do this.

Let us know, and thank you.
