Most of the time, restarting the unit can resolve some significant problems with your oven. It is advisable to try restarting your oven whenever facing a bug before calling a repairer.

You can restart your oven by pressing the power button for 10 seconds. Once the oven is turned off, you can switch off the power button on the board and unplug it from the wall socket.

After unplugging the unit, you must let it rest for at least 5 minutes. This will help cool down the oven’s internal temperature and correct any bugs in it.

Once done, plug the oven back into the socket and turn it on. Most of the time, you will see the error disappear after you have restarted the unit. You can try other repair techniques to solve the problem if the error is still there.

2. Claiming Your Warranty

As an F3 error represents a problem with the sensor, you must check whether it is functioning well. You can locate the temperature sensor in the appliance by checking the manufacturer’s guide.

Primarily, the sensor is located at the rear wall on the inside of the oven cavity. It is visible as a small mounting plate fixed to the wall by two screws. This help to keep the sensor in its place.

At first, you will need to clean the temperature sensor nicely in order to remove any debris or food particles accumulating over it. Next, you can check the wiring of the sensor. Make sure it is not broken or damaged.

You can also check the cables attached to the oven temperature sensor and look for any issues with them. If the wiring is loose, damaged, or broken, you must consider repairing it as soon as possible. Since the damaged wiring can provoke the risk of any other electrical danger, such as a spark or fire, it is recommended not to turn on the oven until the wiring is repaired.

4. Replacing the Sensor

If the temperature sensor is in a very pathetic condition and seems to be irreparable, you can replace it with a new one.

For that, you will need to perform the following steps:

  • Turn off the power to the oven and unplug it from the wall socket.
  • Remove the oven racks from the inside.
  • Locate the temperature sensor and remove the mounting screws.
  • Pull the temperature sensor inwards to access the wire connector.
  • Use a needle-nose plier to remove the wire connector from the wiring plug.
  • Connect the new temperature sensor in place of the previous one by connecting the wire connections in place.
  • Use a nut screwdriver to tighten the new temperature sensor in its place.
  • Restore the power to the oven and check the performance of the new sensor.

If you have no experience repairing electrical appliances yourself, do not perform the replacement on your own. Dealing with wires and electric cords is an extremely sensitive task and must be done by an experienced person. Otherwise, the problem can worsen and get difficult to handle.
