Two problems. The bottom oven now won't heat up to proper temperature. Also, when cooking at high temp in the top oven, the control panel will stop working until i cools down

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.

Hello. In most ovens with an electronic control, the temperature is regulated by 2 things--the sensor and the oven control board. The sensor is simply an electrically resistive device that changes resistance as the temperature increases or decreases. It is connected to the main control board by 2 wires(just a "pigtail") and the main board is supposed to be calibrated to adjust properly. Most control boards have a built-in program by which you can adjust the calibration +/- 35 degrees. If your oven is outside that range, and you're sure that the sensor is good, the connections are good, etc., then the oven control board temp control circuit has gone bad. Keep in mind, when you turn on an electronically controlled oven, the first time it heats up is USUALLY hotter by about 50 degrees--this allows the floor, walls, and ceiling to reach proper temperature. This is called the initial spike. In gas ovens, the user must wait approximately 8-10 minutes AFTER the oven beeps to cook anything. In an exposed-element electric oven, the user waits approximately 10-15 minutes after the beep. In the hidden bake element models, waiting 20-25 minutes after the beep is normal!
Also, keep in mind, ovens can have 60 degree temp swings higher and lower(as long as the midpoint is close to the chosen temp) I hope I've helped you!

Stick a thermometer inside the oven. Compare the them inside the oven to the temp you see on the control panel; are they the same?
You must do this first. You will note a disrepancy. If the oven temp and yours do not match, that you have solved the problem.
Your oven sensor or thermostat might be at fault.

The temperature sensor in the oven needs to be replaced. Here is the part to order. As far as the top element, lift the top up and look for lose or broken wires on the element. Keep me posted.

You have a bad control board and oven temperature sensor. I highly recommend disconnecting the power source until the repair is made.

Also the fact it is a convection oven could mean the oven temperature sensor is not picking up the oven temp. it is not telling the machine it is there by the board seeing its resistance, the unit will shut off as a safety feature. The oven sees temperature by reading the value of a temperature dependent resistor. As the temperature changes so does the value of the component ( oven temp sensor) that way the unit determines the temperature inside the unit. Sometimes those sensors will break since they are in the area with the heat and moisture, they get old and break.

If both elements are not working properly then the problem is either the temperature probe or the control board.

Replace the temp probe first.

I have just checked the baking guide in the manual and have found that it may not be us after all. (Maybe this is why they telll us to read the whole manual. Well, I never have) According to the cooking time for Baking, the range is very extensive. For example, an angel cake at 350 could take from 28-50 minutes, buscuits at 375-400 could take 8-16 minutes, layer cakes at 350-375 could take 25-40 minutes, pound cakes at 325-350 could take 45-70 minutes and fresh pies at 400-450 could take 35-60 minutes. Basically, the baking directions on the box means absolutely nothing to use Amana oven owners. We have no choice but to cook our food or baked goods until they are cooked, whenever that may be. :) Linda

hi,
F2
Oven over temp - exceeded 590F with door in unlocked position or 990F with door locked - If actual temp condition occurred, look for welded relay contacts or high resistance connection or any cause in the oven temperature sensor circuit

F2
Note: Also see fan thermal switches - Indicates that oven is over temperature in one of the following modes within either a cooking or clean mode of operation.
· Control senses oven temperature above 650 degrees F with the door circuit in the unlock mode.
· Control senses oven temperature above 935 degrees F with the door in the locked mode.
· Stalled cooling fan or airflow problem.

· Look for welded relay contacts. (Heating elements on in off mode).
· Look for open thermal switch in lock motor circuit. Switch is normally closed and will open if area overheats due to fan not operating. Look for cause - fan thermal switch not closing, fan stalled, etc.
· Look for high resistance in the oven temperature sensor circuit due to high contact resistance (poor terminal crimp, deformed terminals, loose connection) or intermittent solder joint on control or intermittent oven temperature sensor.

Most modern gas ovens and many broilers use a "glow-bar" style of igniter that glows red-hot to ignite the gas. If the igniter doesn't reach the proper temperature, the gas valve won't open. You may need to replace the igniter.
