Oven continues to preheat and the temperature does not increase

There are several potential causes for a gas range being slow to preheat. Here are some troubleshooting steps you can try:

1. Check the igniter: While the igniter may be coming on, it may not be getting hot enough to ignite the gas. Make sure the igniter is clean and free from any debris or corrosion. If it is dirty, gently clean it with a soft cloth. If the igniter is damaged or not getting hot enough, it may need to be replaced.
2. Check the gas supply: Make sure that the gas supply is turned on and that the gas pressure is sufficient. If the gas pressure is too low, the oven may take longer to preheat.
3. Check the oven temperature sensor: A faulty temperature sensor can cause the oven to take longer to preheat. Use a multimeter to test the sensor for continuity. If it is not working properly, it may need to be replaced.
4. Check the oven door seal: A faulty oven door seal can cause heat to escape, making it difficult for the oven to reach the desired temperature. Inspect the seal for any cracks or gaps, and replace it if necessary.
5. Check the oven igniter safety valve: The igniter safety valve is responsible for regulating the flow of gas to the oven. If it is faulty, it may be restricting the flow of gas, causing the oven to take longer to preheat.

If you are uncomfortable performing any of these troubleshooting steps yourself, it is best to contact a qualified appliance repair technician for assistance.

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.

One must preheat the oven to the desired baking temperature. If the oven is turned on and the food immediately put in to bake, it will take longer to bake the first batch than the second and subsequent batches, because the oven need a few minutes to heat up.

In other words, the oven isn't at 350 degrees the instant you turn it on. It takes about 15 minutes for the oven to reach 350 degrees. I hope this helps.

Hello,
Your oven will continue to indicate that it is preheat mode until the thermostat senses the proper set temperature. If you are getting no heat then you will need to address that issue. This could be many things but the most notorious would be the heating element. Could be the control panel as well. Some ovens have a knob for preheat, bake and clean with a separate knob to adjust the temperature. Make sure both are set properly.

Most likely the problem is your bake element. When the oven is preheating it uses both the bake and the broil element. When it's done preheating it uses only the bake element, so the broil element is heating it up, and since the bake element is not working the temperature drops until it starts preheating again.

Hi,
It is probably as simple as changing the ignitor...
The ignitor is not working right and is going bad....
have the repair man replace the ignitor, or DIY....

Are both of your heating elements lighting up when you are preheating? It sounds like the oven thinks it is pumping power into both elements and one isn't working. Oven elements are generally easy to remove and replace!

I need to bake in my oven how can I find the button to set the temp to bak?

Cold Stove, you may not be able to. The issue here is that oven manufactures put on their units a fast preheat. However it isn't possible to preheat an oven for 7 to 9 minutes and bake short time bake items properly. Also the oven sensor will respond faster than the absorbation rate of the sheet metal in the oven liner. To preheat an oven properly takes 15 to 20 minutes before putting in the food. I see this will a lot of current ovens. Sounds like a normal format of the control.

Is this a gas unit? If so you might have a weak oven igniter.
