At what temperatures can an oven bag resist without burning or leaking?

I suggest cooking food into oven bags at maximum 180 degrees celsius to prevent leakage, and for less than one hour. However it's always a good idea to put a tray or container under the bag so that in case there is some leakage, the sauce can be retrieved and it won't burn on the oven's floor. Another solution to prevent leakage is putting two bags one into the other, so to provide double protection.
In any case, whatever temperature you cook at or for however long, never put the bag too close to the sides of the oven or too close to its top or bottom. Closeness to very hot surfaces raises the chances of melting the plastic and therefore causing leakage.

You sound like you have a temp sensor error. Without knowing your exact model I'd say that you can open the door with a coat hangar , the latch is at the top in the center it is locked to the right (facing the front of the door), and it is spring loaded

Remove the temp sensor and take a ohm reading.
Appliance Tip of the Day: Oven Temperature Sensors Demystified Everyone knows what thermostats do: turn something on and off based on temperature. If your range has an electronic range control (ERC) board with the digital LED display, it doesn't have a thermostat. You know what I'm talking about, most ERCs look something like this.
Ranges with ERCs use a sensor to "feel" the temperature in the oven cavity and sends that information to the ERC. The ERC then makes decisions about about heating the oven and controls the burner (in gas ovens) or heating elements (in electric ovens). Typical styles of range temperature sensors are shown
Inevitably, your range will one day start acting goofy and you'll need to check the oven sensor to see if it's causing a problem. On most ranges, a big clue that the sensor is the problem is if you're getting an F1 error code in your ERC display. So how do you check the sensor? Keep reading.
Oven sensors sense the temperature is the oven cavity by increasing their internal resistance, measured in ohms as the oven's temperature increases. This change in ohm resistance tells the ERC the oven cavity temperature and it turns the heating elements or burner on and off, as needed. Now, hang with me, grasshopper, 'cuz we're getting to the good part.
At room temperature, 70°F, the resistance of the most common sensors used today is 1000-1100 ohms. What this means is that if you pull those sensor wires to measure the sensor's resistance and it reads slap-a$$ open, why, it don't take a rocket scientist like myself to figger out that you got yourself a bad sensor! Wasn't that easy?
Just for grins, I've included the table below to show you the sensor resistance reading at various temperatures. Viva la resistance!

The bag can be made from plastic or nylon. It has to be a material that can reach high temperatures without being affected.

OK, what has happen here is, the actual temp sensor has failed during the cleaning process, this has cause a temp that reached a dramatic high range(above 915F-930F). At these temps, there will be major damage that will weld the contacts on the door lock switch mechanism and control board.

If actual over temperature condition occurred: Look for welded relay contacts. If this happens, replace oven control (also called clock or ERC).

If no over temperature condition occurred: Look for a high resistance connection or any other cause of high resistance in the oven temperature sensor circuit.

Check door lock switches for faults as well(welded contacts and burned wiring harness)

Remember: Oven control (ERC) measures resistance of sensor circuit , not actual oven temperature.

The F10 indicates that the electronic oven control board senses a runaway temperature condition in the oven through the oven sensor circuit.
This can be caused by a faulty oven temperature sensor probe or a failed electronic control board.
Oven temperature is detected by the control board as it monitors the resistance through the oven temperature sensor circuit.
You could have a failed oven temperature sensor, a wiring harness failure, an open thermal switch or a failed electronic oven control board that would cause this problem.
The first component to check would normally be the oven temperature sensor probe.
If you have a volt/ohm meter, you can shut off the breaker for the range and remove the screws that mount this sensor to the back wall of the oven.
Carefully pull the wire harness into the oven cavity until you get to the wire harness disconnect plug.
You should have enough slack to pull it this far into the oven.
Disconnect the sensor but do not let the wire harness retract back through the back wall of the oven or it will be hard to reconnect.
Measure the resistance of the oven temperature sensor with your volt/ohm meter. At room temperature, the resistance should measure around 1100 ohms.
The resistance chart is shown in the image below.

If the resistance is above 2200 ohms at room temperature, then the sensor probe is causing the F10 error code and will need to be replaced.

You can order a new sensor probe from the Sears PartsDirect website. The part number for the sensor is 316217002.

If the resistance is normal, then one of the other causes mentioned above is producing your F10 code.
You would need to access the electronic oven control board (Timer) in the console and check the resistance at the sensor circuit connection to the control board as the next step in troubleshooting this problem.
