Oven is baking uneven

If your built-in electric oven is getting to temperature and then quitting during a bake cycle, and the upper heating element is not working during the bake cycle but works on the broil setting, it is possible that the problem is with the bake element. Here are some troubleshooting steps you can take:

1. Check the bake element: The bake element is the heating element located at the bottom of the oven. To check if the bake element is working properly, turn on the oven and set it to bake mode. Open the oven door and look at the bake element. It should be glowing red. If it is not, then the bake element is likely faulty and needs to be replaced.
2. Check the oven temperature sensor: The oven temperature sensor is a small probe that is located inside the oven. Its job is to monitor the temperature inside the oven and communicate that information to the oven's control board. If the sensor is faulty, it may cause the oven to shut off prematurely. You can test the sensor with a multimeter to see if it is working properly. If it is not, then it needs to be replaced.
3. Check the oven control board: If both the bake element and the oven temperature sensor are working properly, then the problem may be with the oven's control board. The control board is responsible for controlling the oven's heating elements and other functions. If it is faulty, it may be shutting off the oven prematurely. In this case, the control board will need to be replaced.

It is recommended to hire a qualified technician to perform these tests and replace any faulty parts to avoid any risks of electrical shock or damage to the oven.

It does sound like the element may be bad. The control will cycle the bake and broil elements to even the heat in the oven. if the element is out the oven won't heat well.

Good Morning Friend,

I understand you want to know how to turn on the oven on your Frigidaire range, model# FGF337GUD. First, make sure you have set the clock. You will do this by pressing the "Clock Set" button and then press and hold down the up or down arrows, until the correct time shows. After you have set the clock, you are ready to turn your oven on.

To set the temperature for your oven, you will press the "Bake" button and three dashes will appear. Press the up and down arrows to change the temperature. Note: The temperature will begin at a default temperature of 350 degrees. Once you have released the up or down arrow, your oven will begin heating to the selected temperature. When your oven reaches the desired temperature, it will beep once.

To cancel the baking function, you will press the "Clear/Off" button.

If you wish to change the temperature after baking has begun, you will press the bake button again, and then change the temperature by pressing the up or down arrows to either increase or decrease the temperature.

I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your air conditioner status has changed successfully. Hope this is helpful.

The bake element
is the heating element that is found at the bottom of the oven. Most electric ovens use both the bake element and the broil element in a bake cycle, with the bake element performing 90% of the heating. If the bake element isn't working, the oven may not heat. To help determine if the bake element is defective you should first do a visual check. If the element is blistered or separated then it should be replaced. If the element appears to look normal, then turn the oven on to a bake function for a minute and then turn it off.

Check the element for signs of heating and if it is still cold then it may be defective. Disconnect the power and then remove the back panel. First check the wires as they may have become loose or corroded. If the element appears to be fine visually, test it for continuity with a multi-meter. ( by placing the each of the meter prongs on each end of the heater element connectors) If the element is burned or no longer has continuity, it will need to be replaced.

The oven safety valve
(also called the gas valve) is the part that ensures that gas is not released until the igniter has reached the correct temperature needed to ignite the gas. While this part can fail, it is uncommon. If the hot surface igniter does not glow you should first verify that you have voltage to the circuit. This is a live voltage check and should be performed by a qualified person. If voltage is lost at the valve terminals then you should verify the continuity of the bi-metal in the valve using a multi-meter.

I will say that is the control board that is not working properly. Have you try to unplugged for phew minutes?, this will reset the current settings. If not, I will star replacing the control board. Good Luck!.

is this 400c or 400f

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!

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

If this is an older oven, check to see if it has a control knob or switch labeled "manual and "hold". Make sure it's set for manual. The hold setting maintains temp at about 140 degrees.
If not the case, is this gas or electric?
