Oven overheats. It doesn't matter to the temperature you set it. The oven temperature goes higher.

Replace oven temperature sensor

350 will be the design max for your oven unless the handbook says for your model is higher rated and is faulty
repair or replace with a higher rated temp oven

It could be the thermostat is defect, an overheat protection is defect and does not close while the temperature is low enough. or the heater is defect.
When the heater and grill are separated, please try the grill. If it does not work I think the thermostat is defect. Most of the time there is no extra fuse in the oven.
When the oven is working on 2 or 3 separate groups, please check if one of the mains fuses has tripped.

500 degrees farenheit is 260 degrees celcius (metric)
any chance the display is set for metric ?

Hello Sonya,
The E0-F2 error code means that the oven temperature was higher than it's supposed to be. Usually the oven overheats because of a defective oven temperature sensor and the sensor should be checked. this is what the sensor looks like...it is located within the oven chamber(usually in the left side) to check it,it needs to unplugged and using a mulitmeter set to measure ohms,check the sensor to be between 1060-1100 ohms at room temp. if the sensor is way lower/higher that 1060-1100 at room temp the sensor is bad and needs to be replaced, if the sensor is within that range then the control board is the problem.

the temparature controller could be faulty or the temparature probe is bad, before rplacement check that the probe is ints possition

There is a temperature switch that shuts the power down if the temperature goes too high. This is to prevent a fire if your thermostat sticks on. Sometimes the switch will become weak and open the circuit at too low of a temperature. Replacing the switch should solve your problem.

If you need more assistance, post a comment with the model and s/n of your stove.

Thanks,

Tim

Bad thermostat, Your thermostat needs to be replaced. That is causing your temperature to go higher then what you call for

Temp probe/thermometer inside oven dirty, or off attachment, or defective. On some models, a small screw head adjustment is provided to calibrate thermometer under dial knob. Else, I would just set dial 50 degrees higher rather than expense of new thermometer or dial.

probably the element. to save wasting money, check continuity with a multimeter
