Have a Whirlpool Accubake, when you set the oven temp, it heats up, but gets much hotter, burning whatever I'm attempting to cook.

Could be oven temperature sensor.

with the on switch for the oven the higher the numbers the hotter the oven
the thermostat will do the controlling at the temp you set
If that is not happening replace the switch

I am not sure about this, but sounds like a connector is on backwards or in the wrong place.

Good Afternoon Andrea,

I see that you're having issues with your Frigidaire oven, and the heating element being red hot the entire time you were cooking no matter how much you turned the temperature down.

I suggest giving your appliance a hard reset. You will do this by either unplugging it or cutting the power off at the circuit breaker for at least 2-3 minutes. When power is restored to your oven, you will need to set the clock by entering in the time and pressing start. Preheat the oven, to whatever desired temperature, and if it is still running hotter than it should be, I suggest you contact your local authorized technician. I hope this is helpful.

-Best Regards-

possible thermostat problem in the switch
call the technician or get the part from tyhe servide agent spares

What do you mean that it wont stay on? Does it turn off and on during cooking? Does it just go off and wont come back on? The oven thermostat regulates the heat in the oven and the oven element and the oven indicator light will turn off and on during cooking. If it stayed on constantly on full oven element power everything would burn.

Hi, your oven will not heat if the temp sensor is faulty or damaged. this code represents a non-responsive oven temp sensor.

Replace Oven temperature sensor (RTD)

You should always preheat oven to operating temperature before cooking anything.
Do not put too much in oven, leave plenty af space for good air circulation.
Do not place any reflective foil or the like on the bottom of oven or shelves, as this reflects heat, and you will get uneven cooking.
Make sure fan is working efficiently if it is fan assisted.

electric oven heats to correcect temp then drops and does not get back too appropriate temp. For example, set at 400, gets there then drops to 275-300
