How do I troubleshoot an F2 error on my GE Oven F20?

Start by measuring the temperature sensor's resistance at room temperature, which should be approximately 1100 Ω. If the reading is significantly higher (e.g., 1600 Ω), the sensor may be faulty. Also inspect the wiring between the sensor and the Electronic Range Control (ERC) for any defects, corrosion, or loose connections that could add resistance.
