Oven will not pre-heat properly

If your Frigidaire oven is not heating up to the high temperature, there could be a few possible causes:

1. The thermostat may be malfunctioning: The thermostat controls the temperature of the oven and if it's not working correctly, it could prevent the oven from reaching the high temperature.
2. The heating element may be malfunctioning: If the heating element is not working properly, the oven may not be able to reach the high temperature.
3. The control board may be malfunctioning: If the control board is not functioning properly, it may not be sending the correct signals to the heating element or thermostat, preventing the oven from reaching the high temperature.
4. The oven may be in a cleaning or self-cleaning cycle: when the oven is in a cleaning cycle, the temperature is raised to a high level to clean the interior of the oven.
5. The oven may be in a energy saver mode: some ovens have a energy saver mode that decrease the temperature by a certain degree to save energy.

It is a common problem with a defective main board. You may re-flow the soldering yourself by this procedure.

Re-Flow Soldering Procedure for Main Board

1.Pre-heat your kitchen oven to 385 degree (No more than 400 degree);

2.Put the main board on a card board (like a pizza box board) in the oven;

3.Heat it for 10 minutes (No more than 10 minutes);

4.Turn the oven off & leave the door open, at this moment, do not touch or move the board until it colds down to the room temperature.

5.Install the board in the TV & try it out.

35 minutes per kg in 180 Celsius oven so 3 and a half hours .
I would add 30 minutes to make sure and pre heat oven before putting in oven .

I have a Kitchen Aid convection wall oven. It takes 6 - 7 minutes to preheat to 325 degrees. You probably have a bad element. There are 2 elements.

Your oven sensor has gone bad and telling the control board/thermostat to keep heating. Find the model number on the range and go to a parts distributor like repairclinic.com or apdepot.com and order you sensor. This is an easy repair.

Hi,
If your electric oven is taking too long to heat or just not heating up right,then check out this tip that will give more detail about your problem.

Oven Problems Electric Oven is Heating Slowly or Poorly

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.

Hi Angela,

There are many different possibilities that can cause this issue. From a faulty thermostat, to placement of the food in the oven, or not giving the oven enough time to pre-heat before placing your food item in the oven to be cooked. I have found that on many ovens they can reach well over 450 degrees during the pre-heating cycle. I had a customer who called because her new oven was burning her brownies on the outside and they were not done on the inside. The customer told me that she would wait for the pre-heat signal beep(oven is ready) before putting the tray of brownies in the oven. When I initially checked the oven tempature using a fluke meter and a thermocouple at the center of the oven I found that the oven was close to 460 degrees when the beep went on to indicate the oven is ready! So that is why she was burning her brownies. It took another 10 minutes after that for the oven to stabalize and keep the tempature at 350. So you might want to give your oven 20 or 30 minutes of pre-heating time before you put your tray of Lasagna in the oven. Always make sure to place the food item at the center most part of the oven. And if you are cooking several trays make sure to stagger their position on each rack so they are not right above/below each other. The positioning is important because it can interrupt the natural flow of heat in the oven. So if you let it pre-heat for a half hour and are still having the burning issue then you should have the oven tested for proper calibration to make sure the thermostat is working properly.

get a new oven

Try shutting off the breaker for about 10 minutes - then bring the power back on
