When the F3 code flashes on your GE oven, this indicates that there is a fault with the oven temperature sensor. There are a few parts that could be causing the fault. These include the wire harness, control board or the oven temperature sensor itself.
In order to locate the source of the error, it is important to take it one step at a time. An ohmmeter can be used to test the resistance of the temperature sensor. You should also test the wire harness and control board for any possible problems or loose wires. Diagnosing the fault requires an understanding of the intricate nature of the appliance as well as the right tools. Improper techniques or tools can cause more harm than good.
The problem could be caused by something as simple as a loose connection. Alternatively, a part might need to be replaced. After determining the cause of the fault, a technician needs to perform the replacement. Attempting the part replacement or repair yourself can result in additional damage. More damage results in more delays and higher repair costs.
If your GE oven is still under warranty, you should contact the manufacturer to report the fault. If your appliance is out of warranty, you should choose a reliable and reputable local appliance repair technician. Any trustworthy repair technician should offer a guarantee for the work performed.
In some cases, you might notice that your oven flashes F2 and F3 error codes back and forth. This is another indication of a temperature sensor fault and the solution involves the same steps mentioned above.
